Engine Air Cleaner/Filter The engine air cleaner/filter is located on the driver's side of the engine compartment. See "Engine Compartment Overview" in the Index for more information on location. To check or replace the engine air cleaner/filter do the following: 1. Loosen the two clips on the top of the engine air cleaner/filter housing and lift the filter cover tabs out of the housing. 2. Push the filter cover housing toward the engine, compressing the duct convolutes. 3. Pull out the filter. 4. Check or install a new engine air cleaner/filter. See "Normal Maintenance Replacement Parts" in the Index. 5. To reinstall the cover, position the tabs through the slots on the housing. A notch on the sides of the filter cover will indicate the correct engagement. Re-clip the two clips on the top of the housing when you are finished. Refer to the Maintenance Schedule to determine when to replace the air filter. See "Scheduled Maintenance Services" in the Index. 6-19
