For 1990-2009 cars

## Explanation of Scheduled Services Delete

The following text and illustrations describe the details of the required scheduled maintenance services.

For time and/or mileage intervals of scheduled maintenance items, refer to Maintenance Schedule .

For information on the proper fluids and lubricants to use, refer to Fluid and Lubricant Recommendations .

### Engine Oil and Filter Change

Change both the engine oil and the filter according to the maintenance schedule intervals.

Clean the gasket sealing area on the engine oil filter mounting surface. Lightly oil gasket with clean oil and install filter. After the oil filter gasket contacts the oil filter mounting surface, tighten 3/4 to 1 full turn. when necessary, use a cap type wrench, AC Delco OF16W or equivalent or strap type wrench with swivel handle to insure proper installation. With engine oil level at proper level, run engine three minutes and thoroughly check filter area for leaks.

For time and/or mileage intervals of scheduled maintenance items, refer to Maintenance Schedule .

#### Engine Oil Quality

Oils recommended for the vehicle can be identified by looking for the Starburst symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API).

#### Engine Oil Viscosity

Notice: Using oils of any viscosity other than those recommended could result in engine damage. When choosing an oil, consider the range of temperatures the vehicle will be operated in before the next oil change. Then, select the recommended oil viscosity.

The recommended oil viscosity for this vehicle is 5W-30.

However, SAE 10W-30 can be used if it is going to be -18°C (0°F) or above.

Engine oil viscosity (thickness) has an effect on the fuel economy and the cold-weather operation (starting and oil flow). Lower viscosity engine oils can provide better fuel economy and cold-weather performance. However, higher temperature weather condition require higher viscosity engine oils for satisfactory lubrication. If the vehicle will be in an area where the temperature falls below -29°C (-20°F), consider using either an SAE 5W-30 synthetic oil or an SAE 0W-30 synthetic oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. Do not use other viscosity oils, such as SAE 20W-50.

### Chassis Lubrication

Notice: Do not lubricate the parking brake cables. Lubrication destroys the plastic coating on the cable.

Lubricate the transaxle shift linkage. Lubricate the underbody contact points and linkage.

### Tire and Wheel Inspection and Rotation

Rotate the tires to equalize the wear and obtain maximum tire life. Refer to Tire Rotation in Tires and Wheels.

Check the tires for abnormal wear or damage. If irregular or premature tire wear exists, refer to Tire Diagnosis - Irregular or Premature Wear in Tires and Wheels.

### Brake System Inspection

Inspect the brake lines and hoses for binding leaks, cracks or chafing. Refer to Brake Hose Inspection in Hydraulic Brakes. Inspect the disc brake pads for wear. Refer to Brake Pad Inspection in Disc brakes. Inspect the rotors for poor surface condition. Inspect other brake system components, including the brake calipers and the parking brake. Check the parking brake adjustment. The brakes may need to be inspected more often if the customer's driving habits or conditions result in frequent braking.

### Drive Belt Inspection

Inspect the belt for the following:

• | Cracks

• | Fraying

• | Wear

• | Proper tension

Replace accessory drive belt as needed. (Belts can have many small cracks in individual ribs without affecting the performance).

### Transaxle Service

Change both the fluid and the filter according to the maintenance schedule intervals.

For time and/or mileage intervals of scheduled maintenance items, refer to Maintenance Schedule .

For information on the proper fluids and lubricants to use, refer to Fluid and Lubricant Recommendations .

### Cooling System Service

Drain, flush and refill the cooling system with new coolant. Refer to Draining and Filling Cooling System in Engine Cooling.

### Spark Plug Replacement

Replace the spark plugs according to the maintenance schedule intervals.

For time and/or mileage intervals of scheduled maintenance items, refer to Maintenance Schedule .

### Spark Plug Wire Inspection

Clean the spark plug wires and inspect for burns, cracks or other damage. Check the wire boot fit at the coils and at the spark plugs. Replace spark plug wires as needed.

### Air Cleaner Filter Replacement

Replace the air cleaner filter according to the maintenance schedule intervals.

For time and/or mileage intervals of scheduled maintenance items, refer to Maintenance Schedule .

### Fuel Tanks, Cap and Lines Inspection

Inspect the following components for damage or leaks:

• | The fuel tank

• | The fuel cap

• | The fuel lines

• | The fuel rails

• | The fuel injection assemblies

Inspect the fuel cap gasket for an even filler neck imprint and any damage. Replace parts as needed.

Periodic replacement of the fuel filter is not required.
