Book Excerpt: 1999-2006 Chevrolet Silverado, GMC Sierra Pick-ups, Tahoe, Suburban, Yukon, Denali, Avalanche Repair Manual ENGINE OIL and FILTER CHANGE

1. Frequent oil changes are the most important preventive maintenance procedures that can be done by the home mechanic. As engine oil ages, it becomes diluted and contaminated, which leads to premature engine wear.
2. Although some sources recommend oil filter changes every other oil change, we feel that the minimal cost of an oil filter and the relative ease with which it is installed dictate that a new filter be installed every time the oil is changed.
3. Gather together all necessary tools and materials before beginning this procedure (see illustration).
4. You should have plenty of clean rags and newspapers handy to mop up any spills. Access to the under side of the vehicle may be improved if the vehicle can be lifted on a hoist, driven onto ramps or supported by jackstands. Warning: Do not work under a vehicle which is supported only by a bumper, hydraulic or scissors-type jack.
5. If this is your first oil change, familiarize yourself with the locations of the oil drain plug and the oil filter.
6. Warm the engine to normal operating temperature. If the new oil or any tools are needed, use this warm-up time to gather everything necessary for the job. The correct type of oil for your application can be found in Recommended lubricants and fluids at the end of this Chapter.
7. With the engine oil warm (warm engine oil will drain better and more built-up sludge will be removed with it), raise and support the vehicle. Make sure it's safely supported!
8. Move all necessary tools, rags and newspapers under the vehicle. Set the drain pan under the drain plug. Keep in mind that the oil will initially flow from the pan with some force, position the pan accordingly.
9. Being careful not to touch any of the hot exhaust components, use a wrench to remove the drain plug near the bottom of the oil pan (see illustration). Depending on how hot the oil is, you may want to wear gloves while unscrewing the plug the final few turns.
10. Allow the oil to drain into the pan. It may be necessary to move the pan as the oil flow slows to a trickle. ...continue with steps 11 through 30.
