- Use an oil filter wrench (cap or band type) to loosen the filter, then spin it off by hand.
- Make sure the old rubber gasket comes off with the old filter (not stuck to the engine).
Step 6: Install the new oil filter
- Wipe the engineās filter sealing surface clean with shop rags.
- Lightly oil the new filterās rubber gasket using a dab of fresh oil on a gloved finger.
- Spin the new filter on by hand until the gasket touches, then tighten.
- If you can fit your torque wrench (10-80 Nm range) with the correct adapter for your oil filter wrench (cap type): Torque to 12 Nm (9 ft-lbs)
- If you canāt torque it: tighten by hand about 3/4 turn after gasket contact.
Step 7: Reinstall the undertray
- Reposition the undertray and start all screws/clips by hand.
- Use a Phillips screwdriver and flat trim clip tool to secure all fasteners snugly.
Step 8: Add new engine oil
