Prepare & Safety First

Park on level ground, engage parking brake. Allow engine to cool for at least 30 minutes. Have drain pan and proper tools ready.

Remove Old Filter

Use a filter wrench to loosen and remove the existing filter. Let residual fluid drain completely into your pan.

Prep New Filter

Apply a thin coat of clean oil or fuel to the new filter's gasket seal. This ensures a proper, leak-free seal.

Install & Torque

Thread the new filter on by hand until gasket contacts, then tighten 3/4 to 1 full turn. Do NOT over-torque.

Start & Verify

Start the engine and let it idle for 2–3 minutes. Check for leaks. Check fluid level and top off if needed.
