Engine Air Cleaner/Filter See Engine Compartment Overview on page 6-12 for the location of the engine air cleaner/filters. To inspect or replace the filters, do the following: When to Inspect the Engine Air Cleaner/Filters Inspect the air cleaner/filters at the Maintenance II intervals and replace them at the first oil change after each 50,000 mile (83 000 km) interval. See Scheduled Maintenance on page 7-4 for more information. If you are driving in dusty/dirty conditions, inspect the filters at each engine oil change. How to Inspect the Engine Air Cleaner/Filters To inspect the air cleaner/filters, remove the filters from the vehicle and lightly shake the filters to release loose dust and dirt. If the filters remain caked with dirt, new filters are required. 1. Flip the clasps on the top of the engine air cleaner/filter cover forward to unlatch the cover. 2. Lift the front of the cover at an angle and remove. This is necessary due to the four tabs located on the rear of the cover. 3. Remove the engine air cleaner/filter element and any loose debris that may be found in the air cleaner base. 4. Inspect or replace the filter. 5. Repeat the procedure for the second air cleaner/filter. 6-18
