Chevrolet Corvette 1997 - 2013  | 6.2 V8 Fluid level checks

  • time 5 to 30 minutes
  • difficulty 1
1 Fluids are an essential part of the lubrication, cooling, brake and windshield washer systems. Because the fluids gradually become depleted and/or contaminated during normal operation of the vehicle, they must be periodically replenished. See Recommended lubricants and fluids at the bottom of the page before adding fluid to any of the following components
Note: The vehicle must be on level ground when fluid levels are checked

Engine oil

2 The oil level is checked with a dipstick
3 On all engine models except 6.2L (Z52), 6.2L (LS9) and 7.0L (LS7) engines, the dipstick is attached to the engine block. The dipstick extends through a metal tube down into the oil pan. Engine oil dipstick (A) and oil filler cap (B) locations (5.7L [LS1] V8 engine)
4 On 6.2L (Z52), 6.2 (LS9) and 7.0L (LS7) engine models, the dipstick is mounted onto an external dry sump engine oil tank on the right side of the engine compartment. The dipstick extends directly into the oil tank
5 The oil level should be checked before the vehicle has been driven, or about 5 minutes after the engine has been shut off. If the oil is checked immediately after driving the vehicle, some of the oil will remain in the upper part of the engine, resulting in an inaccurate reading on the dipstick
Note: On 6.2L (Z52), 6.2 (LS9) and 7.0L (LS7) engine models, the oil level must be checked when the engine is warm. The oil level in the dry sump oil tank may not give an accurate reading when the engine is cold
6 Pull the dipstick out of the tube or tank and wipe all the oil from the dipstick with a clean rag or paper towel. Insert the clean dipstick all the way back into the tube or tank and pull it out again. Note the oil at the end of the dipstick or cross-hatched area. At its highest point, the level should be between the MIN and MAX marks on the dipstick (see illustration) or in between the cross-hatch area
6a The oil level should be in the safe range - if it’s below the MIN or ADD mark (A), add enough oil to bring it up to or near the MAX or FULL mark (B)
7 It takes one quart of oil to raise the level from the MIN mark to the MAX mark on the dipstick. Do not allow the level to drop below the MIN mark or oil starvation may cause engine damage. Conversely, overfilling the engine (adding oil above the MAX mark) may cause oil fouled spark plugs, oil leaks or oil seal failures
8 To add oil on all engine models except 6.2L (Z52), 6.2 (LS9) and 7.0L (LS7) engine models, remove the filler cap from the valve cover on 6.2L (Z52), 6.2 (LS9) and 7.0L (LS7) engine models, remove the filler cap from the top of the dry sump oil tank. After adding oil, wait a few minutes to allow the level to stabilize, then pull out the dipstick and check the level again. Add more oil if required. Install the filler cap and tighten it by hand only
9 Checking the oil level is an important preventive maintenance step. A consistently low oil level indicates oil leakage through damaged seals, defective gaskets or past worn rings or valve guides. If the oil looks milky in color or has water droplets in it, the cylinder head gasket(s) may be blown or the head(s) or block may be cracked. The engine should be checked immediately. The condition of the oil should also be checked. Whenever you check the oil level, slide your thumb and index finger up the dipstick before wiping off the oil. If you see small dirt or metal particles clinging to the dipstick, the oil should be changed

Engine coolant

Warning: Do not allow antifreeze to come in contact with your skin or painted surfaces of the vehicle. Flush contaminated areas immediately with plenty of water. Don’t store new coolant or leave old coolant lying around where it’s accessible to children or pets - they’re attracted by its sweet smell. Ingestion of even a small amount of coolant can be fatal! Wipe up garage floor and drip pan spills immediately. Keep antifreeze containers covered and repair cooling system leaks as soon as they’re noticed
Warning: Do not remove the expansion tank cap when the engine is warm
10 10 All vehicles covered by this manual are equipped with a pressurized coolant recovery system. A plastic coolant expansion tank is located at the right side fender (2004 and earlier models) or left side fender (2005 and later models) of the engine compartment and is connected by hoses to the cooling system. As the engine heats up during operation, the expanding coolant fills the tank. On 2004 and earlier models, the coolant expansion tank is located at the right side of the engine compartment
11 The coolant level in the tank should be checked regularly. The level in the tank varies with the temperature of the engine. When the engine is cold, the coolant level should be at the FULL COLD mark on the reservoir. If it isn’t, remove the cap from the tank and add a 50/50 mixture of DEX-COOL antifreeze and water
Warning: Do not remove the expansion tank cap to check the coolant level when the engine is warm
12 Drive the vehicle, let the engine cool completely and then recheck the coolant level. Don’t use rust inhibitors or additives. If only a small amount of coolant is required to bring the system up to the proper level, water can be used. However, repeated additions of water will dilute the antifreeze and water solution. In order to maintain the proper ratio of antifreeze and water, always top up the coolant level with the correct mixture. An empty plastic milk jug or bleach bottle makes an excellent container for mixing coolant
Warning: Never remove the expansion tank cap when the engine is running or has just been shut down, because the cooling system is hot. Escaping steam and scalding liquid could cause serious injury. If it is necessary to open the expansion tank cap, wait until the system has cooled completely, then wrap a thick cloth around the cap and slowly unscrew it. If you hear hissing or any steam escapes, wait until the system has cooled further, then remove the cap
13 If the coolant level drops within a short time after replenishment, there may be a leak in the system. Inspect the radiator, hoses, expansion tank cap, drain plugs, and water pump. If no leak is evident, have the expansion tank cap pressure tested
14 When checking the coolant level, always note its condition. It should be relatively clear. If it is brown or rust colored, the system should be drained, flushed and refilled. Even if the coolant appears to be normal, the corrosion inhibitors wear out with use, so it must be replaced at the specified intervals
15 Do not allow antifreeze to come in contact with your skin or painted surfaces of the vehicle. Flush contacted areas immediately with plenty of water

Brake and clutch fluid

16 The brake master cylinder is mounted on the front of the power booster unit in the engine compartment. The hydraulic clutch master cylinder reservoir used on manual transmission vehicles is next to the brake booster
17 The brake master cylinder and the clutch master cylinder have their own reservoirs. To check the fluid level of either system, simply look at the MAX and MIN marks on the brake fluid reservoir (arrowed)
18 If the level is low, wipe the top of the reservoir cover with a clean rag to prevent contamination of the brake system before lifting the cover
19 Add only the specified brake fluid to the reservoir (refer to Recommended lubricants and fluids in your owner’s manual). Mixing different types of brake fluid can damage the system. Fill the reservoir only to the MAX line
Warning: Use caution when filling the reservoir - brake fluid can harm your eyes and damage painted surfaces. Do not use brake fluid that is more than one year old or has been left open. Brake fluid absorbs moisture from the air. Excess moisture can cause a dangerous loss of braking
20 While the reservoir cap is removed, inspect the master cylinder reservoir for contamination. If deposits, dirt particles or water droplets are present, the system should be drained and refilled
21 After filling the reservoir to the proper level, make sure the lid is properly seated to prevent fluid leakage
22 The fluid in the brake master cylinder will drop slightly as the brake pads at each wheel wear down during normal operation. If the master cylinder requires repeated replenishing to keep it at the proper level, this is an indication of leakage in the brake or clutch system, which should be corrected immediately. If the brake system shows an indication of leakage, check all brake lines and connections, along with the calipers and booster (see for more information). On manual transmission vehicle, also check all clutch lines and connections, along with the clutch release cylinder
23 If, upon checking the brake fluid level, you discover the reservoir empty or nearly empty, the systems should be bled

Windshield washer fluid

24 Fluid for the windshield washer system is stored in a plastic reservoir located at the left rear of the engine compartment
25 In milder climates, plain water can be used in the reservoir, but it should be kept no more than 2/3 full to allow for expansion if the water freezes. In colder climates, use windshield washer system antifreeze, available at any auto parts store, to lower the freezing point of the fluid. Mix the antifreeze with water in accordance with the manufacturer’s directions on the container
Caution: Do not use cooling system antifreeze - it will damage the vehicle’s paint

Power steering fluid

26 Check the power steering fluid level periodically to avoid steering system problems, such as damage to the pump
Caution: DO NOT hold the steering wheel against either stop (extreme left or right turn) for more than five seconds. If you do, the power steering pump could be damaged
27 The power steering reservoir, located at the left front of the engine (see illustration) , is checked with a dipstick attached to the cap. For the check, the front wheels should be pointed straight ahead and the engine should be off.
27 The power steering reservoir, located at the left front of the engine (arrowed), is checked with a dipstick attached to the cap. For the check, the front wheels should be pointed straight ahead and the engine should be off
28 Use a clean rag to wipe off the reservoir cap and the area around the cap. This will help prevent any foreign matter from entering the reservoir during the check
29 Twist off the cap and check the temperature of the fluid at the end of the dipstick with your finger
30 Wipe off the fluid with a clean rag, reinsert it, then withdraw it and read the fluid level
30a Use the HOT line on the power fluid steering level dipstick when its hot and . . .
30b . . . the FULL COLD line on the dipstick when the fluid is cold
31 Add small amounts of fluid until the level is correct
Caution: Do not overfill the reservoir. If too much fluid is added, remove the excess with a clean syringe or suction pump
32 Check the power steering hoses and connections for leaks and wear
