GM Service Manual Online
For 1990-2009 cars only

The services shown in this schedule up to 192 000 km (120,000 miles) should be repeated after 192 000 km (120,000 miles) at the same intervals for the life of this vehicle.

Footnotes

The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emissions warranty or limit recall liability prior to the completion of the vehicle's useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.

At Each Fuel Fill

It is important to perform these underhood checks at each fuel fill.

Engine Oil Level Check

Check the engine oil level and add the proper oil if necessary. See Engine Oil.

Notice: It is important to check the engine oil regularly and keep it at the proper level. Failure to keep the engine oil at the proper level can cause damage to the engine not covered by the vehicle warranty.

Engine Coolant Level Check

Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant.

Windshield Washer Fluid Level Check

Check the windshield washer fluid level in the windshield washer fluid reservoir and add the proper fluid if necessary. See Washer Fluid.

Hood Latch Operation Check

Pull the primary hood latch release handle inside the vehicle. The secondary latch should keep the hood from opening all the way when the primary latch is released. Make sure the hood closes firmly. See Hood.

At Least Once a Month

Tire Inflation Check

Inspect the tires and make sure the tires are inflated to the correct pressures. Do not forget to check the spare tire. See Tires.

At Least Twice a Year

Wiper Blade Check

Inspect wiper blades for wear, cracking, or contamination. Clean the windshield and wiper blades, if contaminated. Replace wiper blades that are worn or damaged. See Wiper Blade Replacement and Exterior Care for more information.

Weatherstrip Lubrication

Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather more frequent application may be required. See Recommended Fluids and Lubricants.

Fluid Level Check

Check the power steering pump, rear axle, transfer case, and automatic or manual transmission fluid levels and add as needed. See Automatic Transmission Fluid or Manual Transmission Fluid. Check for leaks. A fluid loss in these systems could indicate a problem. Have the system inspected and repaired at once.

At Least Once a Year

Key Lock Cylinders Service

Lubricate the key lock cylinders with the lubricant specified in Recommended Fluids and Lubricants.

Seat Operation Check

Make sure the head restraints stay in position and all seat latches lock. Check that the recliner holds by pushing and pulling the seatback while it is reclined.

Body Lubrication Service

Lubricate all hood latch assembly, secondary latch, pivots, spring anchor, release pawl, hood and body door hinges, rear compartment, and any folding seat hardware. Recommended Fluids and Lubricants tells you what to use. More frequent lubrication might be required when exposed to a corrosive environment.

Starter Switch Check

See Starter Switch Check.

Automatic Transmission Shift Lock Control System Check

Caution: When you are doing this inspection, the vehicle could move suddenly. If the vehicle moves, you or others could be injured.

  1. Before starting this check, be sure there is enough room around the vehicle. It should be parked on a level surface.
  2. Firmly apply the parking brake. See Parking Brake.
  3. Be ready to apply the regular brake immediately if the vehicle begins to move.

  4. With the engine off, turn the ignition to ON/RUN, but do not start the engine. Without applying the regular brake, try to move the shift lever out of P (Park) with normal effort. If the shift lever moves out of P (Park), contact your dealer/retailer for service.

Ignition Transmission Lock Check

While parked, and with the parking brake set, try to turn the ignition to LOCK/OFF in each shift lever position.

    • For automatic transmission vehicles, the ignition should turn to LOCK/OFF only when the shift lever is in P (Park).
    • For manual transmission vehicles, the ignition should turn to LOCK/OFF only if you push the ignition key in farther, while turning it toward LOCK/OFF.

Contact your dealer/retailer if service is required.

Parking Brake and Automatic Transmission P (Park) Mechanism Check

Caution: When you are doing this check, the vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of the vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.

Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake.

    • To check the parking brake's holding ability: With the engine running and transmission in N (Neutral), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only.
    • To check the P (Park) mechanism's holding ability: With the engine running, shift to P (Park). Then release the parking brake followed by the regular brake.

Contact your dealer/retailer if service is required.

Underbody Flushing Service

At least every spring, use plain water to flush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect.

Periodic Maintenance Inspections

These inspections and services should be performed at least twice a year, for instance, each spring and fall. You should let your dealer/retailer do these jobs. Make sure any necessary repairs are completed at once.

Proper procedures to perform these services can be found in a service manual. See Service Publications Ordering Information.

    • Inspect the front and rear suspension and steering system for damaged, loose, or missing parts or signs of wear. Inspect power steering cables for proper hook-up, binding, cracks, chafing, etc. Clean and then inspect the drive axle boot seals for damage, tears, or leakage. Replace seals if necessary.
    • Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken, damaged, missing, or out-of-position parts as well as open seams, holes, loose connections, or other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes into the vehicle. See Engine Exhaust.
    • Inspect the complete fuel system for damage or leaks.
    • Inspect the cooling system hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps; replace as needed. Clean the outside of the radiator and air conditioning condenser. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year.
    • Inspect the throttle system for interference or binding, and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator and cruise control cables.
    • Inspect the complete brake system. Inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc. You may need to have your brakes inspected more often if your driving habits or conditions result in frequent braking.
