Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery negative terminal to avoid electrical issues.

2. Inspect and Replace Oil Filter

Remove the old oil filter using an oil filter wrench.
Ensure the rubber O-ring from the old filter is removed from the engine.
Apply a small amount of new oil to the O-ring on the new filter.
Install the new oil filter hand-tight, ensuring it is secure but not over-tightened.

3. Check Oil Level and Condition

Using the dipstick, remove it, clean it, and reinsert it to check the oil level.
If oil is low, add the manufacturer-recommended oil type until the correct level is reached.
If the oil appears dirty or contaminated, perform an oil change using fresh oil.

4. Reconnect Battery and Clear Codes

Reconnect the battery negative terminal.
Use the OBD-II scanner to clear any existing trouble codes.
Start the engine and allow it to idle for a few minutes to check for leaks and ensure normal operation.
