When to Inspect the Engine Air Cleaner/Filter Inspect the engine air cleaner/filter every 15,000 miles (25 000 km) and replace it every 30,000 miles (50 000 km). If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change. {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 helps to stop flames if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off. Notice: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/filter in place when you are driving. How to Inspect the Engine Air Cleaner/Filter To inspect the engine air cleaner/filter remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required. To inspect or replace the filter, do the following: 1. Remove the screws and lift off the cover. 2. Inspect or replace the engine air cleaner/filter. 3. Put the cover back on tightly and tighten the screws. See Part A: Scheduled Maintenance Services on page 374 for replacement intervals. 282
