Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery negative terminal to ensure safety during work.

2. Engine Oil Check

Remove the dipstick and wipe it clean with a cloth.
Reinsert the dipstick, then remove it again to check the oil level.
If low, add the recommended engine oil type (5W-30 or as specified in the owner's manual).
Inspect the oil for debris or a burnt smell, indicating possible internal damage.

3. Inspect Timing Belt/Chain

Remove the engine cover (if applicable) using a socket set.
Visually inspect the timing belt or chain for wear, fraying, or misalignment.
If damaged, replace with a new belt/chain and ensure proper tensioning according to manufacturer specifications.

4. Check Exhaust System

Inspect the exhaust system for loose heat shields or components.
Tighten any loose bolts or replace damaged heat shields as necessary.
Ensure that the exhaust manifold is securely attached to prevent rattling noises.

5. Reassemble and Reconnect Battery

Reinstall any components removed during inspection.
Ensure all fasteners are torqued to the manufacturer’s specifications.
Reconnect the battery negative terminal securely.
