Solution

1. Preparation

Gather necessary tools: OBD-II scanner, mechanic's stethoscope, oil catch pan, wrenches, and sockets.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before starting any work on the engine.

2. Change Engine Oil

Drain Old Oil
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow oil to completely drain.
Replace Oil Filter
- Use an oil filter wrench to remove the old oil filter.
- Apply a small amount of new oil to the rubber gasket of the new filter and install it.
Add New Oil
- Reinstall the drain plug and tighten to manufacturer specifications (usually around 30-40 ft-lbs).
- Add the recommended type and amount of new engine oil (typically 0W-20 for this model).

3. Inspect and Replace Components

Engine Components Inspection
- Visually inspect and, if necessary, replace worn or damaged engine mounts.
- Check the timing chain/belt for signs of wear; replace if necessary.
Tensioner Replacement
- If the timing chain tensioner is noisy, remove it and replace it with a new one, ensuring correct torque specifications are followed.

4. Reassemble and Test

Reconnect the battery and start the engine.
Listen for any remaining knocking noises. If absent, take the vehicle for a test drive to ensure normal operation.
