See Engine Compartment Overview for the location of the engine air cleaner/filters.

Notice: If you spray water into the engine air cleaner/filter intake and water enters the engine air cleaner/filter housing, you could damage your vehicle's engine. The repairs would not be covered by your warranty. Do not spray water into the engine air cleaner/filter intake and/or housing.

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 (80 000 km) interval. See Scheduled Maintenance 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.

To inspect or replace the filters:

  1. Some XLR-V vehicles, have a single piece black cover that snaps over the entire air cleaner assembly. For vehicles with this cover, simply pull it's left/right sides toward the outside of the vehicle and lift up to remove cover. Reinstall the cover when you are finished inspecting/replacing the filters.

  2. Object Number: 1863185  Size: B3
  3. For vehicles that do not have a single piece black cover, move the clasps on the top of the engine air cleaner/filter cover forward to unlatch the cover.
  4. 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.
  5. Remove the engine air cleaner/filter and any loose debris that might be found in the air cleaner base.
  6. Inspect or replace the filter.
  7. Repeat the procedure for the second air cleaner/filter.

Reverse the procedure to reinstall the engine air cleaner/filter.

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 the engine, which will damage it. Always have the air cleaner/filter in place when you are driving.
