Installation Guide

1. Ensure the engine is off and has had time to cool down.
2. Place an adequately sized oil drain pan beneath the old oil filter.
3. Using an oil filter wrench, turn the old filter counter-clockwise to loosen and remove it.
4. Carefully wipe the filter mounting surface on the engine block to ensure it is clean and free of old gasket material.
5. Apply a thin, clean film of new engine oil to the gasket of the new filter.
6. Screw the new filter onto the threaded mount by hand until the gasket makes firm contact with the engine block.
7. Tighten the filter an additional 3/4 to one full turn by hand. Do not use a wrench to tighten, as this can cause damage.

9. Start the engine and let it run for a minute, carefully checking for any leaks around the new filter.
10. Turn the engine off, wait several minutes for the oil to settle, then re-check the oil level on the dipstick and top off if needed.
