Do not clean the filter elements by bumping or tapping them. Do not use filter elements with damaged pleats, gaskets or seals. Engine damage can result. Make sure the cleaned filter elements are completely dry before installing into the filter housing. Water remaining in the elements can cause false indications of contamination in Scheduled Oil Sampling test results. |
- When you clean the inside pleats and the outside pleats, direct the air along the pleats or direct the water along the pleats.
The element can be washed in a solution that consists of warm water and of nonsudsing household detergent. Fully rinse the pleats. Allow the filter to air dry completely.
Engine air filter primary elements may be wet for three days. During this time, install a new primary element or install a dry, cleaned element. Store the dry element for installation at the next service.

Place a light bulb inside the filter element. Discard the filter element if you find any of the following conditions:
- Holes of light that are pin hole size
- Areas of paper that appear thin
- Holes of light that are pin hole size

- Cover the clean filter elements. Store the elements in a clean, dry location.
A primary element may be cleaned for a maximum of six times. Also replace the primary element if the primary element has been used for one year.
- Install a clean primary filter element over the engine air filter secondary element. Apply firm pressure to the end of the primary element as you gently rock the filter element. This seats the primary element.
- Clean the cover for the air cleaner housing. Align the slot on the cover with the pin on the air cleaner housing. Install the cover.
- Reset the air cleaner service indicator.
If the yellow piston in the filter element indicator moves into the red zone after starting the engine, or the exhaust smoke is still black after installation of a clean primary filter element, install a new primary filter element.
After six cleanings, the primary element should be replaced. Replace the element annually.
