Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent accidental electrical shorts.

2. Check Oil Level

Remove the dipstick and wipe it clean with a lint-free cloth.
Reinsert the dipstick fully, then remove it again to check the oil level.
If the oil is low, add the appropriate type of oil until it reaches the full mark.

3. Inspect Oil Filter

Use an oil filter wrench to remove the oil filter.
Inspect the oil filter gasket for proper sealing; replace the filter if damaged.
Apply a thin layer of new oil on the gasket of the new filter before installation.
Install the new oil filter and tighten it according to the manufacturer’s specifications.

4. Check for Leaks

After ensuring all components are securely installed, start the engine and let it run for a few minutes.
Inspect the oil filter and drain plug for any signs of oil leaks.
If leaks are present, tighten the components or replace damaged parts.

5. Reset Check Engine Light

Reconnect the battery and use the OBD-II scanner to clear the error codes.
If the check engine light persists, further diagnosis may be required.
