Air Cleaner Housing: Testing and Inspection

Inspection
Visually inspect the air cleaner element and the air cleaner cover and body for signs of dust or dirt leaking through holes in the filter media or past the end seals. Place a light on the inside (clean side) of the air cleaner element and look through the filter media at the light. Even the smallest hole is cause for replacement.

Also check the air cleaner element for deformed seals or brittle spots that could fail under engine operation and cause a hole.
- Discoloration only is not cause for replacement.

NOTE: Cleaning the Air Filter Element is NOT recommended.

Refer to the Maintenance Schedule for the recommended air cleaner element maintenance mileage interval. The air cleaner element should be replaced at the specified mileage intervals.
