When you call, tell the towing service: That your vehicle cannot be towed from the rear with sling-type equipment. That your vehicle has rear-wheel drive. The make, model, and year of your vehicle. Whether you can still move the shift lever. If there was an accident, what was damaged.

When the towing service arrives, let the tow operator know that this manual contains detailed towing instructions and illustrations. The operator may want to see them.

I

When your vehicle is being towed, have he ignition key off. The steering wheel should be clamped in a straight-ahead position, with a clamping device designed For towing service. Do not use the vehicle’s steering column lock for this. The transmission should be in “Neutral” and the parking brake released. Don’t have your vehicle towed on the rear wheels unless you must. If the vehicle must be towed on the rear wheels, don’t go more than 35 mph (55 kmh) or farther than 50 miles (80 km) or your transmission will be damaged. Go slow mer rough ground, and position one wheel at a time (angled 45”) if you have to go over curbs and rises. Wheels at the lifted end should be at least four inches (1 00 mm) above the ground. If these limits must be exceeded, then the rear wheels have to be supported on a dolly.

Engine Overheating

You will find a engine coolant temperature gauge on the instrument cluster and a low coolant light on the Driver Information Center.

NOTICE: Towing a vehicle over rough surfaces could damage a vehicle. Damage can occur from vehicle-to-ground or vehicle-to-wheel-lift-equipment. To help avoid damage, install a towing dolly and raise vehicle until adequate clearance is obtained between the ground and/or wheel-lift equipment.

[f you no longer have the overheat warning, you can drive. Just to be safe, hive slower for about ten minutes. If the warning doesn’t come back on, you can drive normally. [f the warning continues, pull over, stop, and park your vehicle right away. [f there’s still no sign of steam, you can idle the engine for two or three minutes while you’re parked, to see if the warning stops. But then, if you still have the warning, TURN OFF THE ENGINE AND GET EVERYONE OUT OF THE VEHICLE until it cools down. You may decide not to lift the hood but to get service help right away.

NOTICE: If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty.

If No Steam Is Coming from Your Engine: If you get the overheat warning but see 0 1 hear no steam, the problem may not be too serious. Sometimes the engine can ge a little too hot when you: 0 Climb a long hill on a hot day. 0 Stop after high speed driving. 0 Idle for long periods in traffic. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. Turn off your air conditioner. 2. Turn on your heater to full hot at the

highest fan speed and open the window as necessary.

3. If you’re in a traffic jam, shift to “ N ’

(Neutral).

Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see on the LTl engine: 1. Coolant recovery tank 2. Coolant high fill reservoir with

pressure cap

3. Electric engine fans

Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see on the LT5 engine: 1. Coolant recovery tank 2. Coolant high fill reservoir with

pressure cap

3. Electric engine fans

If the coolant inside the coolant recovery tank is boiling, don’t do anything else until it cools down. When it is cool, remove the coolant recovery tank cap and look at the dipstick. The coolant level should be at or above “COLD.” If it isn’t, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.

I NOTICE: I Engine damage from running your

engine without coolant isn’t covered by your warranty.

If there seems to be no leak, check to see if the electric engine fans are running. If the engine is overheating, both fans should be running. If they aren’t, your vehicle needs service.

. . -152

How to Add Coolant to the Coolant Recovery Tank If you haven’t found a problem yet, but the coolant level isn’t at or above the “COLD, mark, add a 50150 mixture of clean water (preferably distilled) and a proper antifreeze at the coolant recovery tank. (See “Engine Coolant” in the Index for more information about the proper coolant mix.)

NOTICE: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recom- mended coolant.

When the coolant in the coolant recovery tank is at or above the “COLD” mark, start your vehicle. If the overheat warning continues, there’s one more thing you can try. You can add the proper coolant mix directly to the coolant high fill reservoir, but be sure the cooling system is cool before you do it.

Turn the pressure cap slowly to the left until it first stops. (Don't press down while turning the pressure cap.) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.

How to Add Coolant to the Coolant High Fill Reservoir - LT1 Only

NOTICE: The LT1 engine (Code P) has a specific coolant high fill reservoir fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged.

1. You can remove the coolant high fill

reservoir pressure cap when the cooling system, including the coolant high fill reservoir pressure cap and upper radiator hose, is no longer hot.

If a tire goes flat, the next section shows how to use your jacking equipment to change a flat tire safely. If your vehicle has Extended Mobility Tires (tires with “EMT” molded on the sidewalls), see “Extended Mobility Tires” in the Index. Changing a Flat Tire If a tire goes flat, avoid further tire damage by driving slowly to a level place. Turn on your hazard warning flashers.

If a Tire Goes Flat

It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to’ leak out slowly. But if you should ever have a ”blowout,” here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well qff the road if possible.

The following steps will tell you how to use the jack and change a tire. Your Corvette wheel lock key has a unique registration number. The registration number is printed on a card included in your locknut package. Also on this card is lost key replacement information. This number is NOT recorded by GM or your dealer, so be sure not to lose this card. You will need the information if you ever lose your wheel lock key. If you have someone else remove your wheels, make sure you give them the special wheel nut socket and wheel lock key. They are under the jack in the rear storage compartment behind the passenger’s seat. The socket can be used with an air or torque wrench. NOTICE: Your wheels could be damaged if the wheel nut socket is not used to remove your Corvette’s wheels.

Always use the wheel nut socket when you use the wheel wrench provided with your Corvette.

- The equipment you’ll need is behind the driver’s seat and in the rear storage compartment behind the passenger’s seat. Move the driver’s seat all the way forward and fold the seatback forward. The wheel wrench is on the floor behind the seat. Loosen the wingnuts and slide the wheel wrench out of the clamps.

The jack, wheel nut socket and wheel ock key are in the rear storage :ompartment behind the passenger’s seat. ]pen the compartment door and remove ,he plastic tray. Lift the jack, wheel nut socket and wheel lock key out of the foan container. You should have a jack, wheel wrench, socket and a wheel lock key.

The spare tire is on a tire carrier Q-ay mder the rear end of your vehicle,. To lower the tray, use the socket end of :he wheel wrench to turn the latch bolt :ounterclockwise. Lower the trag- about an inch. Don’t loosen the latch bplt too much, or the tray could

fall.

NOTICE: Your Corvette’s radio receiver box is in the rear storage compartment. To help avoid damage, carefully place the jack, socket and wheel lock key into the foam container in the compartment. Do not toss or place the items against the radio receiver box or any wiring.

The “LOWELAT TIRE” or “SERVICE LTPWS” light will stay on as long as you ire using the compact spare tire. It should 50 out when the original tire is replaced. 9fter you have the flat tire repaired or eeplaced, install the plastic nut caps and lighten them to 22 pound-inches :2.5 Nom). Put the jack, wheel nut socket and wheel .ock key in the rear storage compartment 3ehind the passenger’s seat. Make sure :he parts are stored properly in the foam Zontainer. Position the jack in the Zontainer so that you can read the yellow CAUTION label from the driver’s seat. Replace the plastic tray and close the storage compartment.

Storing a Flat Tire (Except ZR-1 Rear Tires) The road tire is larger than the spare, so you must adjust the tray to its lower position. Lift and push the tire carrier tray toward the front of the vehicle. The tray will drop to its lower position.

Put the flat road tire on the tray. Lift the latch bolt, push it toward the front of the vehicle, and the bolt will drop down to the lower position.

Put the hooked end of the wheel wrench into the slot in the tray. Lift the tray using the wheel wrench and insert the latch bolt into the notch in the tray. To raise the tray, use the socket end of the wheel wrench to turn the latch bolt clockwise. Turn the latch bolt until it is snug. Put the wheel wrench back in its place under the driver's seat. Be sure to tighten the wingnuts.

167 :. .

Problems on the Road

Storing a Flat Tire (ZR-1 Rear Tires) A ZR-1 rear tire will not fit in the tray, so you must put it on the floor of the rear area. Put the flat tire in the storage bag provided. Place the tire on the rear area floor. Use the luggage straps to hold the tire in place. Loosen the straps, then attach each end of the longer strap to the rear cargo hooks. Attach the other strap to the hook behind the console.

righten the straps by pulling on the loose ends. When the tire is stored in the rear cargo area, you can’t store a removable roof panel. It will not fit into the latches properly. Put the wheel wrench back in its place under the driver’s seat. Be sure to tighten the wingnuts.

Raise the tire carrier tray to its upper position and tighten the latch bolt until it is snug.

Compact Spare Tire Although the compact spare was fully inflated when your vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inflated. The compact spare is made to perform well at posted speed limits for distances up to 3,000 miles (5 000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again.

NOTICE: Tire chains won’t fit your compact spare. Using them will damage your vehicle and destroy the chains too. Don’t use tire chains on your compact spare. If You’re Stuck: In Sand, Mud, Ice or Snow

What you don’t want to do when your vehicle is stuck is to spin your wheels. The method known as “rocking” can help you get out when you’re stuck, but .you must use caution.

169 ...

- NOTICE: Don’t take your compact spare through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle.

Don’t use your compact spare on some other vehicle. And don’t mix your compact spare or wheel with other wheels or tires. They won’t fit. Keep your spare and its wheel together.

Problems on the Road

Rocking your vehicle to get it out: First, turn your steering wheel left and ight. That will clear the area around your front wheels. You should turn your ASR system off. (See “ASR System” in the [ndex.) Then shift back and forth between “R’ (Reverse) and a forward gear (or with 9 manual transmission, between First or Second gear and Reverse), spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. If that doesn’t get you out after a few tries, you may need to be towed out. If you do need to be towed out, see “Towing Your Vehicle” in the Index.

NOTICE: Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transmission back and forth, you can destroy your transmission.

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper Chevrolet Service Manual. It tells you much more about how to service your Corvette than this manual can. To order the proper service manual, see “Service Publications” in the Index. Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air Bag-Equipped Corvette” inthe Index. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index.

I NOTICE: I If you try to do your own service

work without knowing enough about it, your vehicle could be damaged.

Service

Your Chevrolet dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. We hope you’ll want to keep your GM vehicle all GM. Genuine GM parts have one of these marks.

. . .172

Fuel

Use premium unleaded gasoline rated at 91 octane or higher. You may use middle grade or regular unleaded gasolines, but your vehicle may not accelerate as well. The gasoline you use should meet specifications ASTM D4814 in the U.S. and CGSB 3.5-92 in Canada. These fuels should have the proper additives, so you should not have to add anything to the fuel. In the U.S. and Canada, it’s easy to be sure you get the right kind of gasoline (unleaded). You’ll see “UNLEADED’ right on the pump. And only unleaded nozzles will fit into your vehicle’s filler neck. Be sure the posted octane for premium is at least 91 (at least 89 for middle grade and 87 for regular). If the octane is less than 87, you may get a heavy knocking noise when you drive. If it’s bad enough, it can damage your engine. If you’re using fuel rated at 91 octane or higher and you still hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal and you don’t have to

buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem. What about gasoline with blending materials that contain oxygen (oxygenates), such as MTBE or alcohol? MTBE is “methyl tertiary-butyl ether.’’ Fuel that is no more than 15% MTBE is fine for your vehicle. Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more than 10% ethanol is fine for your vehicle. Methanol is methyl or wood alcohol.

NOTICE: Fuel that is more than 5% methanol is bad for your vehicle. Don’t use it. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your warranty. And even at 5% or less, there must be “cosolvents” and corrosion preventers in this fuel to help avoid these problems.

Gasolines for Cleaner Air Your use of gasoline with deposit control additives will help prevent deposits from forming in your engine and fuel system. That helps keep your engine in tune and your emission control system working properly. It’s good for your vehicle, and you’ll be doing your part for cleaner air. Many gasolines are now blended with oxygenates. General Motors recommends that you use gasolines with these blending materials, such as MTBE and ethanol. By doing so, you can help clean the air, especially in those parts of the country that have high carbon monoxide levels. In addition, some gasoline suppliers are now producing reformulated gasolines. These gasolines are specially designed to reduce vehicle emissions. General Motors recommends that you use reformulated gasoline. By doing so, you can help clean the air, especially in those parts of the country that have high ozone levels. You should ask your service station operators if their gasolines contain deposit control additives and oxygenates, and if they have been reformulated to reduce vehicle emissions.

173 ...

Service and Appearance Care Fuels in Foreign Countries If you plan on driving in another country outside the U.S. or Canada, unleaded fuel may be hard to find. Do not use leaded gasoline. If you use even one tankful, your emission controls won’t work well or at all. With continuous use, spark plugs can get fouled, the exhaust system can corrode, and your engine oil can deteriorate quickly. Your vehicle’s oxygen sensor will be damaged. All of that means costly repairs that wouldn’t be covered by your warranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving. You can also write us at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN). General Motors Overseas Distribution

Engine Oil If you have the LTl engine, it’s a good idea to check your engine oil level every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. Turn off the engine and give the oil a few minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level.

5.7L LT5 (Code J) f you have the LT5 engine, the best time 3 check your engine oil is when the ngine is cold. If you run the engine, the ngine oil won’t drain back into the pan ast enough. Give the oil two hours to rain tl le oi :vel. It

When to Add Oil: If the oil is at or below the “ADD’ mark, you’ll need to add some oil. But you musl use the right kind. This section explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index.

NOTICE: Don’t add too much oil. If your engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, your engine could be damaged.

Just fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through.

What Kind of Oil to Use Look for two things:

GM4718M The Corvette engine requires a special oil meeting GM Standard GM47 18M. Oils meeting this Standard may be identified as synthetic. However, not all SYNTHETIC oils will meet this GM Standard. You should look for and use only an oil that meets GM Standard GM47 18M.

(See the manufacturer’s warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

Substitute Oil (LT1 Only): When adding oil to maintain engine oil level, if an oil meeting GM Standard GM4718M is not available, you can use oil designated either SAE 5W-30 API Service SH or SG at all temperatures, or SAE 1OW-30 API Service SH or SG at temperatures above 0°F (-18°C). This oil should not be used for an oil change. Substitute Oil (LT5 Only): When adding oil to maintain engine oil level, if an oil meeting GM Standard GM4718M is not available, you can use oil designated SAE 1OW-30 API Service SH or SG at all temperatures. This oil should not be used for an oil change.

The engine is at low speed most of the time (as in stop-and-go traffic). Most trips are through dusty places.

If any one of these is true for your vehicle, you need to change your oil and filter every 3,000 miles (5 000 km) or 3 months - whichever comes first. (See “Engine Oil Life Monitor” in the Index.) If none of them is true, change the oil every 7,500 miles ( 12 500 km) or 12 months - whichever comes first. Change the filter at the first oil change and at every other oil change after that. (See “Engine Oil Life Monitor” in the Index.)

Engine Oil Additives Don’t add anything to your oil. Your Chevrolet dealer is ready to advise if you think something should be added.

When to Change Engine Oil See if any one of these is true for you:

Most trips are less than 4 miles (6 km). It’s below freezing outside and most trips are less than 10 miles (16 km).

Automatic Transmission Fluid

When to Check and Change 4 good time to check your automatic :ransmission fluid level is when the mgine oil is changed. Refer to the Maintenance Schedule to determine when co change your fluid. See “Scheduled Maintenance Services” in the Index.

How to Check Because this operation can be a little iifficult, you may choose to have this done at a Chevrolet dealership Service Department. [f you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.

NOTICE: Too much or too little fluid can dam- age your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system, starting a fire. Be sure to get an accurate reading if you check your transmission fluid.

Wait at least 30 minutes before checking the transmission fluid level if you have been driving: 0 When outside temperatures are above

90°F (32°C).

0 At high speed for quite a while. 0 In heavy traffic - especially in hot

weather.

To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93°C). To check transmission fluid hot: Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it’s colder than 50°F (10°C)’ drive the vehicle in “D’ (Third Gear) until the engine temperature gage moves and then remains steady for ten minutes. Then follow the hot check procedures. To check transmission fluid cold: A cold check is made after the vehicle has been sitting for eight hours or more with the engine off and is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50” F ( 1 OOC) or more. If it’s colder than 50°F ( 10°C)’ you may have to idle the engine longer. Should the fluid level be low during a

Park your vehicle on a level place. With the parking brake applied, place the shift lever in “P” (Park). 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). Let the engine run at idle for three minutes or more.

Then, without shutting off the engine, Follow these steps: 1. Pull out the dipstick and wipe it with a

clean rag or paper towel.

2. Push it back in all the way, wait three

seconds and then pull it back out again.

3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the cold area for a cold check or in the “HOT” area or cross-hatched area for a hot check. 4. If the fluid level is in the acceptable range, push the dipstick back in all the way.

How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. If the fluid level is low, add only enough of the proper fluid to bring the level up to the cold area for a cold check or the “HOT” area for a hot check. It doesn’t

Then, follow these steps: 1. Remove the filler plug. 2. Check that the lubricant level is up to

the bottom of the filler plug hole. 3. If the fluid level is good, install the plug and be sure it is fully seated. If the fluid level is low, add more fluid as described in the next steps.

How to Add Fluid: Here’s how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. 1. Remove the filler plug.

2. Add fluid at the filler plug hole. Add

only enough fluid to bring the fluid level up to the bottom of the filler plug hole.

3. Install the filler plug. Be sure the plug

is fully seated.

How to Check and Add Fluid The clutch master cylinder is under the Engine Control Module (ECM) in the left rear area of the engine compartment. To check the fluid, look at the area between the ECM and the battery. To add fluid, remove the ECM unit.

Hydraulic Clutch The clutch linkage in your vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid. It isn’t a good idea to “top off’ your clutch fluid. Adding fluid won’t correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

When to Check and What to Use Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid.

Remove the nut on the outboard side of the unit. Then loosen the front and inboard nuts. For the LT5 engine, loosen the two inboard nuts. Move the ECM unit to either side. Fluid should be added if the fluid level is at or below the “ADD” mark on the reservoir. There are additional instructions on the reservoir cap. When returning the ECM to its proper position, make sure the bolts are aligned with the slots in the bracket. Then gently push down on the unit. When replacing the unit, be careful not to over-tighten the nuts -just tighten them until they are snug.

Rear Axle When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Periodic Maintenance Inspections” in the Index.

How to Check Lubricant If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole.

. . * 188

What to Use: To add lubricant when the level is low, use Axle Lubricant (GM Part No. 12345977) or SAE 8OW-90 GL-5 gear lubricant. To completely refill after draining, add 4 ounces (1 18 ml) of Limited-Slip Differential Lubricant Additive (GM Part No. 1052358). Then fill to the bottom of the filler plug hole with Axle Lubricant (GM Part No. 12345977) or SAE 8OW-90 GL-5 gear lubricant. Engine Coolant The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating or if you need to add coolant to your high fill reservoir, see “Engine Overheating” in the Index. The proper coolant for your Corvette will:

Give freezing protection down to -34°F (-37°C). Give boiling protection up to 262°F (128°C). Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights work as they should.

What to Use: Use a mixture of one-half clean water (preferably distilled) and one-half antifreeze that meets “GM Specification 1825-M,” which won’t damage aluminum parts. You can also use a recycled coolant conforming to GM Specification 1825-M with a complete coolant flush and refill. If you use this mixture, you don’t need to add anything else.

NOTICE: If you use an improper coolant mix, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mix can freeze and crack the engine, radiator, heater core and other parts.

Adding Coolant I’o Check Coolant When your engine is ;old, check the dipstick on the cap of the ;oolant recovery tank. The coolant level should be at “COLD,” or a little higher. When your engine is warm, the level on the dipstick should be up to “HOT,” or a little higher. Your Corvette also has a coolant high fill reservoir located at the right rear of the engine compartment.

189 ...

Service and Appearance Care

Thermostat Engine coolant temperature is controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature. When you replace your thermostat, an AC@ thermostat is recommended.

If you need to add more coolant, add the proper mix at the coolant recovery tank, but only when your engine is cool. If the tank is very low or empty, also add coolant to the coolant high fill reservoir. See “Engine Overheating” in the Index for information.

Add coolant mix at the recovery tank, but be careful not to spill it.

NOTICE: 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. Don’t spill coolant on a hot engine.

For complete drain, flush and refill of the engine, contact your Chevrolet jealer or the procedure may be found in 3 Chevrolet Corvette Service Manual. To purchase a service manual, see “Service Publications” in the Index.

Brake Master Cylinder Your brake master cylinder is here. It is filled with DOT-3 brake fluid. There are only two reasons why the brake fluid level in your master cylinder might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all. So, it isn’t a good idea to “top off’ your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

When your brake fluid falls to a low level, your brake warning light, “SERVICE ABS” light and “SERVICE ASR” light will come on. Also, the anti-lock brake and Acceleration Slip Regulation systems are disabled. See “Brake System Warning Light” in the Index.

What to Add: When you do need brake fluid, use only DOT-3 brake fluid - such as Delco- Supreme 1 l@ (GM Part No. 1052535). Use new brake fluid from a sealed container only, and always clean the brak fluid reservoir cap before removing it.

193 ...

Service and Appearance Care

NOTICE:

Don’t let someone put in the wrong kind of fluid. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Brake fluid can damage paint, so be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

Brake Wear Your Corvette has four-wheel 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 may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly).

. . .I94

I NOTICE: I Continuing to drive with worn-out

brake pads could result in costly brake repair.

Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. 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 of brake trouble.

Brake Adjustment As you make brake stops, your disc brakes automatically adjust for wear.

Replacing Brake System Parts The braking system on a modern 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. Vehicles we design and test have top-quality GM brake parts in them, as your Corvette does when it is new. When you replace parts of your braking system - for example, when your brake linings wear down and you have to have new ones put in - be sure you get new genuine GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change, for the worse. The braking performance you’ve come to expect can change in many other ways if someone puts in the wrong replacement brake parts.

Contact your dealer to learn how to prepare your vehicle for longer storage periods.
