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

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

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

For the 4.3L engine oil and filter changing procedure, refer to Engine Oil and Oil Filter Replacement in Engine Mechanical-4.3L.

For the 4.8L, 5.3L, and 6.0L engine oil and filter changing procedure, refer to Engine Oil and Oil Filter Replacement in Engine Mechanical-4.8L, 5.3L, and 6.0L.

Notice: Use only engine oil with the American Petroleum Institute Certified for Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by the warranty.

The STARBURST symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry the STARBURST symbol.

Notice: If you use oils that don't have one of these designations either CH-4 or CG-4, you can cause engine damage which is not covered by the warranty.

Oils designated as API CH-4 or CG-4 are best. The CH-4 or CG-4 designations may appear either alone, together or in combination with other API designations, such as API CH-4/SJ, CG-4/SH or CH-4/CG-4/SJ.

These letters show American Petroleum Institute (API) levels of quality.

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.

Important: If your vehicle is operated in an area where the temperature falls below -29°C (-20°F), consider using a SAE 5W-30 synthetic oil or a SAE 0W-30. Both will provide easier cold starting and better protection for the engine at extremely low temperatures.

Engine oil viscosity, thickness has an effect on fuel economy and the cold-weather operation, engine starting and oil flow. Lower viscosity engine oils can provide better fuel economy and cold-weather performance. However, higher temperature weather conditions require higher viscosity engine oils for satisfactory lubrication.

SAE 5W-30 is best for your vehicle. However, use 10W-30 if the outside temperature is higher than 18°C (0°F). Do not use other viscosity oils, such as SAE 20W-50.

Important: As shown in the viscosity chart, SAE 15W-40 is best for your vehicle. However, you can use SAE 10W-30 if it is going to be colder than (0°C) 32°F before your next oil change. When it is very cold, below (-18°C) 0°F, you should use SAE 10W-30 to improve cold starting. SAE 30 may be used at temperatures above freezing, (0°C) 32°F.

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

Refer to the illustrations for the locations of the lubrication points for the chassis. Lubricate transmission shift linkage. Lubricate the park brake guides, underbody contact points and linkage.

Lubricating Joints that have Grease Fittings

Important: Wipe off all dirt from the grease fitting before lubricating the joint. Ball joints should not be lubricated unless their temperature is (-12°C) 10°F or higher. During cold weather, the ball joint should be allowed to warm up as necessary before being lubricated. Use a low-pressure grease gun on all joints to prevent seal damage.

Refer to the illustration for the location of the grease fittings.
