carried.


Say, for example, you have a 318 kg (700 lb) snow plow. The total weight of all occupants and cargo inside the cab should not exceed 135 kg (300 lb). This means that you may only be able to carry one passenger. But, even this may be too much if there is other equipment already adding to the weight of the vehicle.

Driving and Operating


Here are some guidelines for safely carrying a snow plow on the vehicle: . Make sure the weight on the front and rear axles does not exceed the axle rating for each. For the front axle, if more cargo or passengers must be carried, appropriate counter ballast must be installed rear of the rear axle. Counter ballast must be properly secured so it will not move during driving. Follow the snow plow manufacturer's recommendations regarding rear ballast. Rear ballast may be required to ensure a proper front and rear weight distribution ratio, even though the actual weight at the front axle may be less than the front axle rating.


The snow plow manufacturer or installer can assist you in determining the amount of rear ballast required, to help make sure the snowplow/vehicle combination does not exceed the GVW rating, the front and rear axle ratings, and the front and rear weight distribution ratio. The total vehicle must not exceed the GVW rating.


Front axle reserve capacity is the difference between the Gross Axle Weight Rating (GAWR) and the front axle weight of the vehicle with full fuel and passengers. Basically, it is the amount of weight that can be added to the front axle before reaching the front GAWR. The front axle reserve capacity for the vehicle can be found in the lower right corner of the Certification/Tire label, as shown.

In order to calculate the amount of weight any front accessory, such as a snow plow, is adding to the front axle, use the following formula:


(W x (A + W.B.)) /W.B.= Weight the accessory is adding to the front axle. Where:


W = Weight of added accessory A = Distance that the accessory is in front of the front axle W.B. = Vehicle Wheelbase


Driving and Operating

For example, adding a 318 kg (700 lb) snow plow actually adds more than 318 kg (700 lb) to the front axle. Using the formula, if the snow plow is 122 cm (4 ft) in front of the front axle and the wheel base is 305 cm (10 ft), then:


W = 318 kg (700 lb) A = 122 cm (4 ft) W.B. = 305 cm (10 ft)


(W x (A + W.B.))/W.B. = (318 x (122 + 305))/305 = 445 kg (980 lbs) So, if the front axle reserve capacity is more than 445 kg (980 lbs), the snow plow could be added without exceeding the front GAWR. Heavier equipment can be added on the front of the vehicle if it is compensated for by carrying fewer passengers, less cargo, or by positioning cargo toward the rear. This has the effect of reducing the load on the front. However, the front GAWR, rear GAWR, and the Gross Vehicle Weight Rating (GVWR) must never be exceeded.


{ WARNING


On some vehicles that have certain front mounted equipment, such as a snow plow, it may be possible to load the front axle to the front gross axle weight rating (GAWR) but not have enough weight on the rear axle to have proper braking performance. If the brakes cannot work properly, you could have a crash. To help the brakes work properly when a snow plow is installed, always follow the snow plow manufacturer or installer's recommendation for rear ballast to ensure a proper front and rear weight distribution ratio, even though the actual front weight may be less than the front GAWR, and the total vehicle weight is less than the gross vehicle weight rating (GVWR). Maintaining a proper front and

rear weight distribution ratio is necessary to provide proper braking performance.


Total vehicle reserve capacity is the difference between the GVWR and the weight of the truck with full fuel and passengers. It is the amount of weight that can be added to the vehicle before reaching the GVWR. Keep in mind that reserve capacity numbers are intended as a guide when selecting the amount of equipment or cargo the truck can carry. If unsure of the vehicle's front, rear, or total weight, go to a weigh station and weigh the vehicle. Your dealer can also help with this.


The total vehicle reserve capacity for the vehicle can be found in the lower right corner of the Certification/Tire label as shown previously. See your dealer for additional advice and information about using a snow plow on the vehicle. Also, see Vehicle Load Limits on page 9‑15. Emergency Roof Lamp Provisions Vehicles with the RPO VYU snow plow prep package also have an emergency roof lamp provision package, RPO TRW. Wiring for the emergency roof lamp is provided above the overhead console. See Auxiliary Roof-Mounted Lamp on page 6‑6 for switch location.


Pickup Conversion to Chassis Cab We are aware that some vehicle owners might consider having the pickup box removed and a commercial or recreational body installed. Owners should be aware that, as manufactured, there are differences between a chassis cab and a pickup with the box removed which could affect vehicle safety. The components necessary to adapt a pickup to permit its safe use with a specialized body should be installed by the body builder.

Checking Engine Oil It is a good idea to check the engine oil level at each fuel fill. In order to get an accurate reading, the vehicle must be on level ground. The engine oil dipstick handle is a loop. See Engine Compartment Overview on page 10‑5 for the location of the engine oil dipstick. Obtaining an accurate oil level reading is essential: 1.


If the engine has been running recently, turn off the engine and allow several minutes for the oil to drain back into the oil pan. Checking the oil level too soon after engine shutoff will not provide an accurate oil level reading.


{ WARNING


The engine oil dipstick handle may be hot; it could burn you. Use a towel or glove to touch the dipstick handle.


2. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.


When to Add Engine Oil


If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” in this section for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 12‑2. Notice: Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful

to the engine. If you find that you have an oil level above the operating range, i.e., the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. You should drain out the excess oil or limit driving of the vehicle and seek a service professional to remove the excess amount of oil. See Engine Compartment Overview on page 10‑5 for the location of the engine oil fill cap. Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through. Selecting the Right Engine Oil Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants on page 11‑12.

Specification Use and ask for licensed engine oils with the dexos1® approved certification mark. Engine oils meeting the requirements for the vehicle should have the dexos™1
approved certification mark. This certification mark indicates that the oil has been approved to the dexos1
specification.


Notice: Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. Check with your dealer or service provider on whether the oil is approved to the dexos1 specification.


Viscosity Grade SAE 5W-30 is the best viscosity grade for the vehicle. Do not use other viscosity grade oils such as SAE 10W-30, 10W-40, or 20W-50. Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29°C (−20°F), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. When selecting an oil of the appropriate viscosity grade, always select an oil of the correct specification. See “Specification” earlier in this section for more information. Engine Oil Additives/Engine Oil Flushes Do not add anything to the oil. The recommended oils with the dexos specification and displaying the dexos certification mark are all that is needed for good performance and engine protection.


Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty. What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil.

engine oil and filter must be changed at least once a year and, at this time, the system must be reset. For vehicles without the CHANGE ENGINE OIL SOON message, an oil change is needed when the OIL LIFE REMAINING percentage is near 0%. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level. If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change. Remember to reset the oil life system whenever the oil is changed.


Vehicle Care

How to Reset the Engine Oil Life System Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the system on most vehicles: 1. Display the OIL LIFE


REMAINING on the DIC. If the vehicle does not have DIC buttons, the vehicle must be in P (Park) to access this display. See Driver Information Center (DIC) on page 5‑29.


2. Press and hold the SET/RESET


button on the DIC, or the trip odometer reset stem if the vehicle does not have DIC buttons, for more than five seconds. The oil life will change to 100%.


Engine Oil Life System


When to Change Engine Oil This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions, engine temperature, and miles driven. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed. On some vehicles, when the system has calculated that oil life has been diminished, a CHANGE ENGINE OIL SOON message comes on to indicate that an oil change is necessary. See Engine Oil Messages on page 5‑40. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not necessary for up to a year. The

On all vehicles, the Engine Oil Life System can be reset as follows: 1. Turn the ignition to ON/RUN with


the engine off.


2. Fully press the accelerator pedal


slowly three times within five seconds.


3. Display the OIL LIFE


REMAINING on the DIC. If the display shows 100%, the system is reset. See Driver Information Center (DIC) on page 5‑29.


If the vehicle has a CHANGE ENGINE OIL SOON message and it comes back on when the vehicle is started and/or the OIL LIFE REMAINING is near 0%, the engine oil life system has not been reset. Repeat the procedure.


Automatic Transmission Fluid (4-Speed Transmission)


When to Check and Change Automatic Transmission Fluid A good time to check the automatic transmission fluid level is when the engine oil is changed. Change the fluid and filter at the intervals listed in Maintenance Schedule on page 11‑3 and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 11‑12. How to Check Automatic Transmission Fluid Because this operation can be a little difficult, it may be best to have this done at the dealer service department. If not taken to the dealer, be sure to follow all the instructions here or a false reading on the dipstick could result.


Notice: Too much or too little fluid can damage the transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if checking the transmission fluid. Wait at least 30 minutes before checking the transmission fluid level if you have been driving: . When outside temperatures are


above 32°C (90°F).


. At high speed for quite a while. In heavy traffic — especially in hot weather.


. While pulling a trailer. To get the right reading, the fluid should be at normal operating temperature, which is 82°C to 93°C (180°F to 200°F).


Chevrolet Silverado Owner Manual - 2013 - crc2 - 8/13/12


Black plate (11,1)


Get the vehicle warmed up by driving about 24 km (15 miles) when outside temperatures are above 10°C (50°F). If it is colder than 10°C (50°F), drive the vehicle in 3 (Third) until the engine temperature gauge moves and then remains steady for 10 minutes. A cold fluid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 10°C (50°F) or more. If it is colder than 10°C (50°F), the engine may have to idle longer. Should the fluid level be low during this cold check, the fluid must be checked when hot before adding fluid. Checking the fluid hot will give you a more accurate reading of the fluid level.


Checking the Fluid Level Prepare the vehicle as follows: 1. Park the vehicle on a level


place. Keep the engine running.


2. With the parking brake applied, place the shift lever in P (Park).


3. With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in P (Park).


4. Let the engine run at idle for


three minutes or more.


Then, without shutting off the engine, follow these steps:


1. Locate the transmission dipstick handle with this graphic which is located at the rear of the engine compartment, on the passenger side of the vehicle. See Engine Compartment Overview on page 10‑5 for more information on location.


Vehicle Care


10-11


2. Flip the handle up, then pull out


the dipstick and wipe it with a clean rag or paper towel.


3. Push it back in all the way, wait


three seconds and then pull it back out again.


4. Check both sides of the dipstick,


and read the lower level. The fluid level must be in the COLD area, below the cross-hatched area, for a cold check or in the HOT or cross-hatched area for a hot check. Be sure to keep the dipstick pointed down to get an accurate reading. If the fluid level is in the acceptable range, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place.

Consistency of Readings Always check the fluid level at least twice using the procedure described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If readings are still inconsistent, contact the dealer. How to Add Automatic Transmission Fluid Refer to Recommended Fluids and Lubricants on page 11‑12 to determine what kind of transmission fluid to use. Using a funnel, add fluid down the transmission dipstick tube only after checking the transmission fluid while it is hot. A cold check is used only as a reference. If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It does not take much fluid, generally less than 0.5 Liter (1 Pint). Do not overfill.


Notice: Use of the incorrect automatic transmission fluid may damage the vehicle, and the damages may not be covered by the vehicle warranty. Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants on page 11‑12. . After adding fluid, recheck the fluid level as described under “How to Check Automatic Transmission Fluid,” earlier in this section.


. When the correct fluid level is


obtained, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place.


Automatic Transmission Fluid (6-Speed Transmission)


When to Check and Change Automatic Transmission Fluid It is usually not necessary to check the transmission fluid level. The only reason for fluid loss is a transmission leak or overheated transmission. If a small leak is suspected, then use the following checking procedures to check the fluid level. However, if there is a large leak, then it may be necessary to have the vehicle towed to a dealer service department and have it repaired before driving the vehicle further. Notice: Use of the incorrect automatic transmission fluid may damage the vehicle, and the damages may not be covered by the vehicle warranty. Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants on page 11‑12.


Chevrolet Silverado Owner Manual - 2013 - crc2 - 8/13/12


Black plate (13,1)


Change the fluid and filter at the scheduled maintenance intervals listed in Maintenance Schedule on page 11‑3. Be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 11‑12. How to Check Automatic Transmission Fluid Notice: Too much or too little fluid can damage the transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if checking the transmission fluid.


Before checking the fluid level, prepare the vehicle as follows: 1. Start the engine and park the


vehicle on a level surface. Keep the engine running.


2. Apply the parking brake and


place the shift lever in P (Park).


3. With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, move the shift lever back to P (Park).


4. Allow the engine to idle (500 – 800 rpm) for at least 1 minute. Slowly release the brake pedal.


5. Keep the engine running and


press the Trip/Fuel button or trip odometer reset stem until TRANS TEMP (Transmission Temperature) displays on the Driver Information Center (DIC).


Vehicle Care

6. Using the TRANS TEMP


reading, determine and perform the appropriate check procedure. If the TRANS TEMP reading is not within the required temperature ranges, allow the vehicle to cool, or operate the vehicle until the appropriate transmission fluid temperature is reached.


Cold Check Procedure Use this procedure only as a reference to determine if the transmission has enough fluid to be operated safely until a hot check procedure can be made. The hot check procedure is the most accurate method to check the fluid level. Perform the hot check procedure at the first opportunity. Use this cold check procedure to check fluid level when the transmission temperature is between 27°C and 32°C (80°F and 90°F).

opportunity after the transmission reaches a normal operating temperature between 71°C to 93°C (160°F to 200°F). If the fluid level is in the acceptable range, push the dipstick back in all the way, then flip the handle down to lock the dipstick in place.


Hot Check Procedure Use this procedure to check the transmission fluid level when the transmission fluid temperature is between 71°C and 93°C (160°F and 200°F). The hot check is the most accurate method to check the fluid level. The hot check should be performed at the first opportunity in order to verify the cold check. The fluid level rises as fluid temperature increases, so it is important to ensure the transmission temperature is within range.

When to Check and What to Use


The brake/hydraulic clutch fluid reservoir cap has this symbol on it. The common hydraulic clutch and brake master cylinder fluid reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview on page 10‑5 for reservoir location. How to Check and Add Fluid Visually check the brake/clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The brake/ hydraulic clutch fluid system should be closed and sealed.


Do not remove the cap to check the fluid level or to top‐off the fluid level. Remove the cap only when necessary to add the proper fluid until the level reaches the MIN line.


Engine Air Cleaner/Filter If the vehicle has a diesel engine, see “Pickup Models” under “Engine Air Cleaner/Filter” in the Duramax® Diesel Supplement for the correct inspection and replacement procedures. See Engine Compartment Overview on page 10‑5 for the location of the engine air cleaner/filter. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the scheduled maintenance intervals and replace it at the first oil change after each 80 000 km (50,000 mi) interval. See Maintenance Schedule on page 11‑3 for more information.


If driving on dusty/dirty conditions, inspect the filter at each engine oil change. How to Inspect the Engine Air Cleaner/Filter To inspect the air cleaner/filter, remove the engine air cleaner/filter from the vehicle by following Steps 1 through 6. When the engine air cleaner/filter is removed, lightly shake it to release loose dust and dirt. If the engine air cleaner/filter remains covered with dirt, a new filter is required. Never use compressed air to clean the filter.

An electric engine cooling fan can start even when the engine is not running. To avoid injury, always keep hands, clothing, and tools away from any engine cooling fan.


{ WARNING


Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.


Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 50 000 km (30,000 mi) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL (silicate-free) coolant in the vehicle.


Engine Coolant The cooling system in the vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in the vehicle for 5 years or 240 000 km (150,000 mi), whichever occurs first. The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating on page 10‑21. What to Use


{ WARNING


Adding only plain water or some other liquid to the cooling system can be dangerous. Plain water and other liquids, can boil before the proper coolant mixture will. The coolant warning system is set for the proper coolant mixture. With plain water or the wrong

WARNING (Continued)


mixture, the engine could get too hot but you would not get the overheat warning. The engine could catch fire and you or others could be burned. Use a 50/ 50 mixture of clean, drinkable water and DEX-COOL coolant.


Use a 50/50 mixture of clean, drinkable water and DEX-COOL coolant. If using this mixture, nothing else needs to be added. This mixture: . Gives freezing protection down


to −37°C (−34°F), outside temperature


. Gives boiling protection up to


129°C (265°F), engine temperature


. Protects against rust and


corrosion


. Will not damage aluminum parts


. Helps keep the proper engine

Notice: If improper coolant mixture, inhibitors, or additives are used in the vehicle cooling system, the engine could overheat and be damaged. Too much water in the mixture can freeze and crack engine cooling parts. The repairs would not be covered by the warranty. Use only the proper mixture of engine coolant for the cooling system. See Recommended Fluids and Lubricants on page 11‑12. Never dispose of engine coolant by putting it in the trash, pouring it on the ground, or into sewers, streams, or bodies of water. Have the coolant changed by an authorized service center, familiar with legal requirements regarding used coolant disposal. This will help protect the environment and your health.

Checking Coolant The coolant surge tank is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 10‑5 for more information on location. The vehicle must be on a level surface when checking the coolant level. Check to see if coolant is visible in the coolant surge tank. If the coolant inside the coolant surge tank is boiling, do not do anything else until it cools down. If coolant is visible but the coolant level is not at or above the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant at the coolant surge tank, but be sure the cooling system is cool before this is done.

Vehicle Care


{ WARNING


If no coolant is visible in the surge tank, add coolant as follows:


You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine.


Notice: This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause the engine to overheat and be severely damaged.


{ WARNING


Steam and scalding liquids from a hot cooling system can blow out and burn you badly. Never turn the cap when the cooling system, including the surge tank pressure cap, is hot. Wait for the cooling system and surge tank pressure cap to cool.


1. Remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one full turn. If a hiss is heard, wait for that to stop. A hiss means there is still some pressure left.


2. Keep turning the pressure cap


slowly, and remove it.


The coolant level should be at or above the FULL COLD mark. If it is not, there may be a leak in the cooling system. How to Add Coolant to the Coolant Surge Tank for Gasoline Engines If the vehicle has a diesel engine, see “Cooling System” in the Duramax Diesel Supplement for the proper coolant fill procedure.

mixture to the coolant surge tank until the level reaches the FULL COLD mark.


5. Replace the pressure cap tightly. 6. Verify coolant level after the


engine is shut off and the coolant is cold. If necessary, repeat coolant fill procedure Steps 1 through 6.


Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured.


Engine Overheating If the vehicle has the Duramax® Diesel engine, see the Duramax Diesel Supplement for more information. The vehicle has several indicators to warn of engine overheating. There is a coolant temperature gauge on the vehicle's instrument panel. See Engine Coolant Temperature Gauge on page 5‑15.


Vehicle Care


10-21


In addition, there are ENGINE OVERHEATED STOP ENGINE, ENGINE OVERHEATED IDLE ENGINE, and ENGINE POWER IS REDUCED messages in the Driver Information Center (DIC) on the instrument panel. See Engine Cooling System Messages on page 5‑39 and Engine Power Messages on page 5‑41. If the decision is made not to lift the hood when this warning appears, get service help right away. See Roadside Assistance Program (Mexico) on page 13‑7 or Roadside Assistance Program (U.S. and Canada) on page 13‑11. If the decision is made to lift the hood, make sure the vehicle is parked on a level surface. Then check to see if the engine cooling fans are running. If the engine is overheating, both fans should be running. If they are not, do not continue to run the engine and have the vehicle serviced.


3. Fill the coolant surge tank with the proper mixture to the FULL COLD mark.


4. With the coolant surge tank


pressure cap off, start the engine and let it run until the engine coolant temperature gauge indicates approximately 90°C (195°F). By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper

Notice: Running the engine without coolant may cause damage or a fire. Vehicle damage would not be covered by the warranty. See Overheated Engine Protection Operating Mode on page 10‑23 for information on driving to a safe place in an emergency. If Steam is Coming from the Engine Compartment { WARNING


Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood.


(Continued)


WARNING (Continued)


If you keep driving when the vehicles engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop the engine if it overheats, and get out of the vehicle until the engine is cool. See Overheated Engine Protection Operating Mode on page 10‑23 for information on driving to a safe place in an emergency.


If No Steam is Coming from the Engine Compartment The ENGINE OVERHEATED STOP ENGINE or the ENGINE OVERHEATED IDLE ENGINE message, along with a low coolant condition, can indicate a serious problem.


If there is an engine overheat warning, but no steam is seen or heard, the problem may not be too serious. Sometimes the engine can get a little too hot when the vehicle: . Climbs a long hill on a hot day . Stops after high-speed driving Idles for long periods in traffic Tows a trailer; see Trailer Towing on page 9‑77.


If the ENGINE OVERHEATED STOP ENGINE or the ENGINE OVERHEATED IDLE ENGINE message appears with no sign of steam, try this for a minute or so: 1. Turn the air conditioning off. 2. Turn the heater on to the highest


temperature and to the highest fan speed. Open the windows as necessary.


Chevrolet Silverado Owner Manual - 2013 - crc2 - 8/13/12

3.


If stopped in a traffic jam, apply the brake, shift to N (Neutral); otherwise, shift to the highest gear while driving — D (Drive) or 3 (Third).


If the temperature overheat gauge is no longer in the overheat zone or an overheat warning no longer displays, the vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes. Keep a safe vehicle distance from the vehicle in front. If the warning does not come back on, continue to drive normally. If the warning continues, pull over, stop, and park the vehicle right away. If there is no sign of steam, idle the engine for five minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Also, see “Overheated Engine Protection Operating Mode” later in this section.


Overheated Engine Protection Operating Mode If an overheated engine condition exists and the ENGINE POWER IS REDUCED message displays, an overheat protection mode which alternates firing groups of cylinders helps to prevent engine damage. In this mode, a loss in power and engine performance will be noticed. This operating mode allows the vehicle to be driven to a safe place in an emergency. Driving extended km (mi) and/or towing a trailer in the overheat protection mode should be avoided. Notice: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life system. See Engine Oil on page 10‑6.


Vehicle Care


10-23


Engine Fan If the vehicle has a clutched engine cooling fan, when the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, the fan speed increases as the clutch more fully engages, so an increase in fan noise may be heard. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch disengages. This fan noise may also be heard when starting the engine. It will go away as the fan clutch partially disengages.

Black plate (24,1)


10-24


Vehicle Care


If the vehicle has electric cooling fans, the fans may be heard spinning at low speed during most everyday driving. The fans may turn off if no cooling is required. Under heavy vehicle loading, trailer towing, high outside temperatures, or operation of the air conditioning system, the fans may change to high speed and an increase in fan noise may be heard. This is normal and indicates that the cooling system is functioning properly. The fans will change to low speed when additional cooling is no longer required.


Power Steering Fluid


See Engine Compartment Overview on page 10‑5 for reservoir location.


When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless there is a leak suspected in the system or an unusual noise is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. How to Check Power Steering Fluid To check the power steering fluid: 1. Turn the key off and let the


engine compartment cool down. 2. Wipe the cap and the top of the


reservoir clean.


3. Unscrew the cap and wipe the


dipstick with a clean rag.


4. Replace the cap and completely


tighten it.


5. Remove the cap again and look at the fluid level on the dipstick.


The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark. What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 11‑12. Always use the proper fluid. Notice: Use of the incorrect fluid may damage the vehicle and the damages may not be covered by the vehicle's warranty. Always use the correct fluid listed in Recommended Fluids and Lubricants on page 11‑12.


Washer Fluid


What to Use When windshield washer fluid needs to be added, be sure to read the manufacturer's instructions before use. Use a fluid that has sufficient protection against freezing in an area where the temperature may fall below freezing.


Chevrolet Silverado Owner Manual - 2013 - crc2 - 8/13/12


Black plate (25,1)


Adding Washer Fluid The vehicle has a low washer fluid message on the DIC that comes on when the washer fluid is low. The message is displayed for 15 seconds at the start of each ignition cycle. When the WASHER FLUID LOW ADD FLUID message displays, washer fluid will need to be added to the windshield washer fluid reservoir.


Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 10‑5 for reservoir location.


Notice


. When using concentrated


washer fluid, follow the manufacturer instructions for adding water.


. Do not mix water with


ready-to-use washer fluid. Water can cause the solution to freeze and damage the washer fluid tank and other parts of the washer system.


. Fill the washer fluid tank only


three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full.


. Do not use engine coolant


(antifreeze) in the windshield washer. It can damage the windshield washer system and paint.

Brakes This vehicle has front disc brakes and could have rear drum brakes or rear disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time the vehicle is moving, except when applying the brake pedal firmly.


{ WARNING


The brake wear warning sound means that soon the brakes will not work well. That could lead to a crash. When the brake wear warning sound is heard, have the vehicle serviced.


Notice: Continuing to drive with worn-out brake pads could result in costly brake repair.

Black plate (26,1)


10-26


Vehicle Care


Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque specifications in Capacities and Specifications on page 12‑2. If the vehicle has rear drum brakes, they do not have wear indicators, but if a rear brake rubbing noise is heard, have the rear brake linings inspected immediately. Rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. Drum brakes have an inspection hole to inspect lining wear during scheduled maintenance. When the front brake pads are replaced, have the rear brakes inspected, too.


Brake linings should always be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service might be required. Brake Adjustment Every time the brakes are applied, with or without the vehicle moving, the brakes adjust for wear. Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. The vehicle was designed and tested with top-quality brake parts. When parts of the braking system are replaced, be sure to get new, approved replacement parts. If this is not done, the brakes might not work properly. For example,


installing disc brake pads that are wrong for the vehicle, can change the balance between the front and rear brakes — for the worse. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed.


Brake Fluid


The brake master cylinder reservoir is filled with DOT 3 brake fluid. See Engine Compartment Overview on page 10‑5 for the location of the reservoir.


Chevrolet Silverado Owner Manual - 2013 - crc2 - 8/13/12


Black plate (27,1)


Vehicle Care


10-27


There are only two reasons why the brake fluid level in the reservoir might go down:


The brake fluid level goes down because of normal brake lining wear. When new linings are installed, the fluid level goes back up.


. A fluid leak in the brake


hydraulic system can also cause a low fluid level. Have the brake hydraulic system fixed, since a leak means that sooner or later the brakes will not work well.


Do not top off the brake fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove brake fluid, as necessary, only when work is done on the brake hydraulic system.


{ WARNING


If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system. See “Checking Brake Fluid” in this section.


When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light on page 5‑24. Refer to the Maintenance Schedule to determine when to check the brake fluid. See Maintenance Schedule on page 11‑3. Checking Brake Fluid Check brake fluid by looking at the brake fluid reservoir. See Engine Compartment Overview on page 10‑5.


The fluid level should be above MIN. If it is not, have the brake hydraulic system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark.


What to Add Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 11‑12.

Vehicle Care


Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir.


{ WARNING


With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake fluid.


Notice


. Using the wrong fluid can


badly damage brake hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake hydraulic system can damage brake hydraulic system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of fluid.


. If brake fluid is spilled on the


vehicle's painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on the vehicle. If you do, wash it off immediately.


Battery If the vehicle is a Hybrid, see the Hybrid Supplement for more information. This vehicle has a maintenance free battery (or batteries). Refer to the replacement number on the original battery label when a new battery is needed. See Engine Compartment Overview on page 10‑5 for battery location.
