Caution (Continued)

attempting any repair. Repair the cause of coolant loss, change the oil, and reset the oil life system. See Engine Oil 0 363.

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. 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. The electric engine cooling fans may run after the engine has been turned. off. This is normal and no service is required.

Power Steering Fluid (1500 Series) The vehicle has electric power steering and does not use power steering fluid.

Power Steering Fluid (2500/3500 Series)

See Engine Compartment Overview 0 358 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.

Wait for the power steering system to cool, with the engine off, before checking the fluid. 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 between the ADD and FULL marks. If necessary, add only enough fluid to bring the level up to the hashed area between the ADD and FULL marks.

Vehicle Care

379

What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants 0 466. Always use the proper fluid.

Caution

Use of the incorrect fluid may damage the vehicle and the damages may not be covered by the vehicle warranty. Always use the correct fluid listed in Recommended Fluids and Lubricants 0 466.

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.

Vehicle Care

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 0 358 for reservoir location.

Caution

Caution (Continued)

. Do not use washer fluid that

contains any type of water repellent coating. This can cause the wiper blades to chatter or skip.

. Do not use engine coolant

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

. 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.

. When using concentrated

washer fluid, follow the manufacturer instructions for adding water.

. 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.

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.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9159338) - 2016 - crc - 7/24/15

Caution

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

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 0 472. 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 may be required.

Replacing Brake System Parts Always replace brake system parts with new, approved replacement parts. If this is not done, the brakes may not work properly. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed or parts are improperly installed.

Brake Fluid

The brake master cylinder reservoir is filled with DOT 3 brake fluid. See Engine Compartment Overview 0 358 for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir may go down:

Vehicle Care

381

. Normal brake lining wear. When

new linings are installed, the fluid level goes back up. . A fluid leak in the brake

hydraulic system. Have the brake hydraulic system fixed. With a leak, the brakes will not work well.

Always clean the brake fluid reservoir cap and the area around the cap before removing it. 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 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.

382

Vehicle Care

Warning (Continued)

Add brake fluid only when work is done on the brake hydraulic system.

When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light 0 142. Brake fluid absorbs water over time. Replace brake fluid at the specified intervals to prevent increased stopping distance. See Maintenance Schedule 0 456. Checking Brake Fluid Check brake fluid by looking at the brake fluid reservoir. See Engine Compartment Overview 0 358.

{ Warning

The wrong or contaminated brake fluid could result in damage to the brake system. This could result in the loss of braking leading to a possible injury. Always use the proper brake fluid.

Caution

If brake fluid is spilled on the vehicle's painted surfaces, the paint finish can be damaged. Immediately wash off any painted surface.

Battery - North America The original equipment battery is maintenance free. Do not remove the cap and do not add fluid. Refer to the replacement number shown on the original battery label when a new battery is needed. See Engine Compartment Overview 0 358 for battery location.

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 MIN but not over the MAX mark.

What to Add Use only GM approved DOT 3
brake fluid from a clean, sealed container. See Recommended Fluids and Lubricants 0 466.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9159338) - 2016 - crc - 7/24/15

Infrequent Usage: Remove the black, negative (−) cable from the battery to keep the battery from running down. Extended Storage: Remove the black, negative (−) cable from the battery or use a battery trickle charger.

. When the differential is at

operating temperature (warm), add enough lubricant to raise the level to the bottom of the fill plug (1) hole.

What to Use Refer to Recommended Fluids and Lubricants 0 466 to determine what kind of lubricant to use.

Rear Axle

When to Check Lubricant It is not necessary to regularly check rear axle fluid unless a leak is suspected or an unusual noise is heard. A fluid loss could indicate a problem. Have it inspected and repaired. All axle assemblies are filled by volume of fluid during production. They are not filled to reach a certain level. When checking the fluid level on any axle, variations in the readings can be caused by factory fill differences between the minimum and the maximum fluid volume. Also, if a vehicle has just been driven before checking the fluid level, it may appear lower than normal because fluid has traveled out along the axle tubes and has not drained back to the sump area. Therefore, a reading taken

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9159338) - 2016 - crc - 7/24/15

five minutes after the vehicle has been driven will appear to have a lower fluid level than a vehicle that has been stationary for an hour or two. The rear axle assembly must be supported on a flat, level surface to get a true reading. How to Check Lubricant

Vehicle Care

393

Headlamp Wiring An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off. Windshield Wipers If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart. Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.

A fuse puller is available in the left instrument panel fuse block. The vehicle may not be equipped with all of the fuses, relays, and features shown.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9159338) - 2016 - crc - 7/24/15

394

Vehicle Care

Fuses The wiring circuits in the vehicle are protected from short circuits by fuses. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as you can.

Engine Compartment Fuse Block If the vehicle has a diesel engine, see the Duramax diesel supplement. The engine compartment fuse block is in the engine compartment, on the driver side of the vehicle.

Lift the cover to access the fuse block.

Caution

Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.

. Replace any tires that

the same danger as overloaded tires. The resulting crash could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when the tires are cold.

. Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact — such as when hitting a pothole. Keep tires at the recommended pressure.

. Worn or old tires can cause a crash. If the tread is badly worn, replace them.

(Continued)

have been damaged by impacts with potholes, curbs, etc. Improperly repaired tires can cause a crash. Only the dealer or an authorized tire service center should repair, replace, dismount, and mount the tires.

. Do not spin the tires in

excess of 56 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the tires to explode.

All-Season Tires This vehicle may come with all-season tires. These tires are designed to provide good overall performance on most road surfaces

and weather conditions. Original equipment tires designed to GM's specific tire performance criteria have a TPC specification code molded onto the sidewall. Original equipment all-season tires can be identified by the last two characters of this TPC code, which will be “MS.” Consider installing winter tires on the vehicle if frequent driving on snow or ice-covered roads is expected. All-season tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter tires on snow or ice-covered roads. See Winter Tires 0 402.

Winter Tires This vehicle was not originally equipped with winter tires. Winter tires are designed for increased traction on snow and ice-covered roads. Consider installing winter tires on the vehicle if frequent driving on ice or snow covered roads is expected. See your dealer

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9159338) - 2016 - crc - 7/24/15

for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires 0 419. With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After changing to winter tires, be alert for changes in vehicle handling and braking. If using winter tires: . Use tires of the same brand and

tread type on all four wheel positions.

. Use only radial ply tires of the

same size, load range, and speed rating as the original equipment tires.

Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y, and ZR speed rated tires. If winter tires with a lower speed rating are chosen, never exceed the tire's maximum speed capability.

Low-Profile Tires If the vehicle has P275/55R20, P285/50R20, or P285/45R22
size tires, they are classified as low-profile tires.

Caution

Low-profile tires are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like potholes, or sharp edged objects, or when sliding into a curb. The warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and when possible, avoid contact with curbs, potholes, and other road hazards.

Vehicle Care

403

All-Terrain Tires This vehicle may have all-terrain tires. These tires provide good performance on most road surfaces, weather conditions, and for off-road driving. See Off-Road Driving 0 259. The tread pattern on these tires may wear more quickly than other tires. Consider rotating the tires more frequently than at 12 000 km (7,500 mi) intervals if irregular wear is noted when the tires are inspected. See Tire Inspection 0 416.

Tire Sidewall Labeling Useful information about a tire is molded into the sidewall. The examples show a typical passenger and light truck tire sidewall.

Tire Designations

Tire Size The examples show a typical passenger vehicle and light truck tire size.

Passenger (P-Metric) Tire

(1) Passenger (P-Metric) Tire : The United States version of a metric tire sizing system. The letter P as the first character in

the tire size means a passenger vehicle tire engineered to standards set by the U.S. Tire and Rim Association. (2) Tire Width : The three-digit number indicates the tire section width in millimeters from sidewall to sidewall. (3) Aspect Ratio : A two-digit number that indicates the tire height-to-width measurements. For example, if the tire size aspect ratio is 75, as shown in item C of the tire illustration, it would mean that the tire's sidewall is 75 percent as high as it is wide. (4) Construction Code : A letter code is used to indicate the type of ply construction in the tire. The letter R means radial ply construction; the letter D means diagonal or bias ply construction; and the letter B means belted-bias ply construction.

(5) Rim Diameter : Diameter of the wheel in inches. (6) Service Description : These characters represent the load index and speed rating of the tire. The load index represents the load carrying capacity a tire is certified to carry. The speed rating is the maximum speed a tire is certified to carry a load.

Light Truck (LT-Metric) Tire

(1) Light Truck (LT-Metric) Tire : The United States version of a metric tire sizing system. The letters LT as the first two characters in the tire size mean a light truck tire engineered to standards set by the U.S. Tire and Rim Association.

(2) Tire Width : The three-digit number indicates the tire section width in millimeters from sidewall to sidewall. (3) Aspect Ratio : A two-digit number that indicates the tire height-to-width measurements. For example, if the tire size aspect ratio is 75, as shown in item 3 of the light truck (LT-Metric) tire illustration, it would mean that the tire's sidewall is 75 percent as high as it is wide. (4) Construction Code : A letter code is used to indicate the type of ply construction in the tire. The letter R means radial ply construction; the letter D means diagonal or bias ply construction; and the letter B means belted-bias ply construction. (5) Rim Diameter : Diameter of the wheel in inches. (6) Load Range : Load Range.

(7) Service Description : The service description indicates the load index and speed rating of a tire. If two numbers are given as in the example, 120/116, then this represents the load index for single versus dual wheel usage (single/dual). The speed rating is the maximum speed a tire is certified to carry a load.

Tire Terminology and Definitions Air Pressure : The amount of air inside the tire pressing outward on each square inch of the tire. Air pressure is expressed in kPa (kilopascal) or psi (pounds per square inch). Accessory Weight : The combined weight of optional accessories. Some examples of optional accessories are automatic transmission, power windows, power seats, and air conditioning.
