Solution

1. Preparation

Safety Warning: Ensure the vehicle is on a level surface and the engine is cool before starting work.
Gather necessary tools and parts.

Tools Required: Oil filter wrench
Remove the oil filter using the wrench. Check for any rubber O-ring residue on the engine.
Install a new oil filter, ensuring the O-ring is lubricated and properly seated.
