Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect Engine Oil

Remove the oil dipstick and wipe it clean, then reinsert and remove it again to check the oil level.
If oil is low, add the manufacturer-recommended oil type.
If oil is dirty or contaminated, proceed to change the oil and replace the oil filter.

3. Replace Serpentine Belt (if worn)

Loosen the tensioner using a socket wrench.
Remove the old serpentine belt from the pulleys and inspect pulleys for damage.
Route the new serpentine belt according to the belt routing diagram, ensuring it sits properly in the grooves.
Reapply tension using the tensioner and check for proper alignment.

4. Tighten Loose Components

Inspect and tighten any loose bolts or fasteners on the heat shields and exhaust system.
Use a torque wrench to ensure bolts are tightened to manufacturer specifications.

5. Test Drive

Reconnect the negative battery terminal.
Start the engine and listen for any abnormal noises.
Take the vehicle for a short test drive to monitor for any remaining issues.
