Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

Tools Required:

Socket set
Torque wrench
Oil catch pan
Clean rags
UV light (if dye is used)

2. Drain Engine Oil

Place an oil catch pan under the oil pan.
Remove the drain plug using a socket wrench and allow the oil to fully drain into the catch pan.
Replace the drain plug and torque it to the manufacturer's specifications (typically around 15-25 ft-lbs).

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, ensuring it is hand-tightened.

4. Repair or Replace Leaking Components

If the oil pan is damaged, remove it by loosening the bolts and carefully prying it off.
Clean the mating surface and replace with a new oil pan or sealant as necessary.
If the valve cover gasket is leaking, remove the valve cover by detaching the bolts and replace the gasket with a new one.

5. Refill Engine Oil

Fill the engine with new oil through the oil fill cap, using the recommended oil type (typically 5W-20 for this model).
Check the oil level with the dipstick and add oil as necessary.

6. Final Checks

Reconnect the battery.
Start the engine and let it idle for a few minutes while checking for leaks around the oil filter, drain plug, and any replaced gaskets.
