Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before starting any electrical work.

2. Inspect and Correct Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
- If the oil level is low, add the recommended oil type (consult the owner’s manual for specifications).
- If the oil level is excessively high, siphon out the excess oil.

Use an oil filter wrench to remove the oil filter.
Inspect the rubber gasket on the old filter for damage; ensure it did not stick to the engine.
Install a new oil filter, ensuring the gasket is lubricated and properly seated.

4. Inspect Oil Drain Plug

Place a drain pan under the oil pan.
Use a socket wrench to check the oil drain plug for tightness.
- If loose, tighten it to the manufacturer’s specification (typically around 25 Nm, but consult the manual).
- If leaking, replace the drain plug washer and retighten.

5. Reconnect Battery and Reset Check Engine Light

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any error codes and reset the check engine light.
