- Remove oil filter using the 24mm (or 15/16″) socket, extension and ratchet
- With the oil filter cap removed, remove and replace housing o ring and filter
- Reinstall oil filter with housing and torque to 18 ft lbs
- Reinstall and torque oil drain plug to 20 ft lbs
- Fill just under 5 quarts of engine oil with oil fill funnel and reinstall oil fill cap
- Start engine to let the engine build oil pressure so the dipstick level will be accurate and shut engine back down
