Lexus 90915-20003 Oil Filter Sub-Assembly

Frequent oil changes are the best preventive maintenance for the engine, as aging oil becomes diluted and contaminated, leading to premature engine wear. Before starting the procedure, ensure that you have all the necessary tools, such as a drain pan, rubber gloves, breaker bar, socket, and filter wrench. Access to the underside of the vehicle is improved if it can be lifted on a hoist, driven onto ramps, or supported by jack stands. Familiarize yourself with the location of the oil drain plug before getting under the vehicle. Park the vehicle on a level spot, start the engine, and let it reach its normal operating temperature. Turn off the engine and remove the filler cap. Raise the vehicle and support it securely on jack stands. Place the drain pan under the drain plug and remove the plug using the proper size wrench or socket. Allow the old oil to drain into the pan and inspect it for metal shavings. Wipe off the drain plug and clean the area around the drain plug opening. Reinstall and tighten the plug securely. Move the drain pan under the oil filter and loosen the filter using an oil filter wrench. Unscrew the filter by hand, wipe off the mounting surface on the block, and ensure no old gasket remains. Smear engine oil on the rubber gasket of the new filter and screw it into place. Remove all tools and lower the vehicle. Add new oil to the engine through the oil filler cap and pour three quarts of fresh oil. Wait for the oil to drain into the pan and check the level on the dipstick. If necessary, add enough oil to bring it to the full mark. Allow the engine to run for about a minute and check for leaks at the drain plug and oil filter. Tighten if necessary. Recheck the oil level and add more if needed. After an oil change, check for leaks and proper oil level during the first few trips. The old oil should be discarded at an oil reclamation center or other suitable disposal site.

First of all, oil changes are key for preventing engine wear. Remove the oil filler cap, raise the vehicle, and locate the oil drain plug. Also, check for metal shavings, clean the plug, and reinstall. Place the pan under the filter, loosen it, and unscrew it. Lubricate the new filter's gasket and install it.

Dispose of the old oil at an oil reclamation center or designated facility for proper recycling.
