Solution

1. Preparation

Gather tools: socket set, oil filter wrench, torque wrench, oil catch pan, clean rags, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Remove the Oil Filter

Place an oil catch pan under the oil filter to catch any residual oil.
Use an oil filter wrench to unscrew the oil filter. Turn it counterclockwise until it is removed.
Check the rubber gasket on the old oil filter; if it remains stuck to the engine, remove it.

3. Inspect and Clean

Inspect the oil filter mount for any debris or old oil.
Clean the mount surface with a clean rag to ensure a proper seal for the new filter.

4. Install New Oil Filter

Apply a small amount of new oil to the rubber gasket of the new oil filter. This helps ensure a good seal.
Screw the new oil filter onto the mount by hand until snug; then, tighten it according to the manufacturer's specifications (usually about 3/4 turn after the filter contacts the mount).

Inspect oil cooler lines and connections for leaks. Tighten or replace as necessary.
If any lines are damaged, remove the old line and install a new one according to the manufacturer's specifications.

6. Refill Engine Oil

If necessary, refill the engine oil to the proper level. Use the recommended oil type specified in the owner's manual.
Start the engine and let it idle for a few minutes while checking for leaks around the filter and oil cooler lines.
