Engine Air Cleaner/Filter Checking or Replacing the Engine Air Cleaner/Filter 1. Remove the two clamps, on the duct, with a flathead screwdriver. 2. Remove the duct. 3. Unlatch the two hooks on top of the engine air cleaner/filter housing. 4. Remove and replace the engine air cleaner/filter. 5. Align the tabs located on the bottom of the panel with the slots at the bottom of the housing. 6. Latch the hooks to secure the panel in place. If the panel moves easily, check that the tabs are seated correctly in the slots. 7. Put the duct back on and replace the clamps. The engine air cleaner/filter is located at the front of the engine compartment on the driver's side of the vehicle, under the engine coolant reservoir. See "Engine Compartment Overview" in the Index for more information on location. CAUTION: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn't there, and the engine backfires, you could be burned. Don't drive with it off, and be careful working on the engine with the air cleaner/filter off. 6-16
