Chevrolet Traverse 2009 - 2013  | 3.6 V6 Fluid level checks

  • time 5 to 30 minutes
  • difficulty 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

1 The engine oil level is checked with a dipstick that extends through a tube and into the oil pan at the bottom of the engine (see below)
2 Engine oil dipstick (A) and oil filler cap (B). To prevent dirt from contaminating the engine, always make sure the area around the cap is clean before removing it
3 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 engine components, resulting in an inaccurate reading on the dipstick
4 Pull the dipstick out of the tube and wipe all the oil from the end with a clean rag or paper towel. Insert the clean dipstick all the way back into the tube, then pull it out again. Note the oil at the end of the dipstick
5 The oil level must be maintained within the cross-hatched zone at all times - it takes about one quart of oil to raise the level from the bottom of the zone to the top of the zone
6 Do not overfill the engine by adding too much oil since this may result in oil-fouled spark plugs, oil leaks or oil seal failures
7 Oil is added to the engine after unscrewing a cap from the valve cover. A funnel will help to reduce spills
8 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 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. Rinse off spills immediately with plenty of water. Antifreeze is highly toxic if ingested. Never leave antifreeze lying around in an open container or in puddles on the floor; children and pets are attracted by its sweet smell and may drink it. Check with local authorities on disposing of used antifreeze. Many communities have collection centers that will dispose of antifreeze safely
Caution: Never mix green-colored ethylene glycol antifreeze and orange-colored DEX-COOL silicate-free coolant because doing so will destroy the efficiency of the DEX-COOL coolant, which is designed to last for 100,000 miles or five years
Note: Non-toxic antifreeze is now manufactured and available at auto parts stores, but even this type should be disposed of properly
1 All vehicles covered by this manual are equipped with a coolant reservoir that is connected by a hose to the radiator filler neck
2 The coolant reservoir is located on the right side of the engine compartment
3 The coolant level in the reservoir should be checked regularly
Warning: Never unscrew the expansion tank cap when the engine is warm. Only remove the cap when the engine and cooling system is cool
4 When the engine is cold, the coolant level must be up to the COLD FILL mark
5 To add coolant, open the cap and add a 50/50 mixture of DEX-COOL coolant and water until the level is up to the COLD FILL mark (see the Caution at the beginning of this section)
6 Drive the vehicle and recheck the coolant level. 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. Do not use rust inhibitors or additives
7 If the coolant level drops consistently, there may be a leak in the system. Inspect the radiator, hoses, filler cap, drain plugs and water pump. If no leaks are noted, have the radiator cap tested by a service station
8 Check the condition of the coolant as well. 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, so it must be replaced at the specified intervals. If the system is filled with standard green coolant/water, it must be flushed and replaced more frequently than if the original DEX-COOL coolant is retained

Windshield washer fluid

1 Fluid for the windshield washer tank is located in a plastic reservoir
2 The tank is located at the left front corner of the engine compartment
3 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: Don’t use cooling system antifreeze - it will damage the vehicle's paint
4 To help prevent icing in cold weather, warm the windshield with the defroster before using the washer

Battery electrolyte

These vehicles are equipped with a battery which is permanently sealed (except for vent holes) and has no filler caps. Water doesn’t have to be added to these batteries at any time. If a maintenance-type battery is installed, the caps on the top of the battery should be removed periodically to check for a low electrolyte level. If the level is low, add only distilled water until the level is above the plates

Brake fluid

1 The brake master cylinder is mounted on the upper left of the engine compartment firewall
2 The translucent plastic reservoir allows the fluid inside to be checked without removing the cap
3 The brake fluid reservoir is located at the left side of the firewall. Wipe the top of the reservoir cap with a clean rag to prevent contamination of the brake system before removing it
4 When adding fluid, pour it carefully into the reservoir to avoid spilling it on surrounding painted surfaces. Be sure the specified fluid is used, since mixing different types of brake fluid can cause damage to the system. See Recommended lubricants and fluids at the bottom of the page or your owner’s manual
Warning: Brake fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling or pouring it. Do not use brake fluid that has been standing open or is more than one year old. Brake fluid absorbs moisture from the air. Moisture in the system can cause a dangerous loss of brake performance
5 At this time, the fluid and master cylinder can be inspected for contamination. The system should be drained and refilled if deposits, dirt particles or water droplets are seen in the fluid
6 After filling the reservoir to the proper level, make sure the cap is installed tight to prevent fluid leakage
7 The brake fluid level in the master cylinder will drop slightly as the pads at the front wheels wear down during normal operation. If the master cylinder requires repeated additions to keep it at the proper level, it’s an indication of leakage in the brake system, which should be corrected immediately. Check all brake lines and connections
8 If, upon checking the master cylinder fluid level, you discover the reservoir empty or nearly empty, the brake system should be bled and thoroughly inspected
