Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during inspection.

2. Inspect Engine Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick, then remove it again to check the oil level.
- If oil is low, add the manufacturer's recommended oil type until the correct level is reached.
If the oil is dirty or contaminated, proceed to the next step.

3. Change Engine Oil and Filter

Place a drain pan beneath the oil pan.
Use a socket set to remove the oil drain plug and allow the oil to drain completely.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug with a torque value of approximately 25 Nm (18 lb-ft).
Fill the engine with the appropriate engine oil (refer to the owner's manual for specifications).

4. Inspect and Replace Serpentine Belt (if necessary)

Loosen the tensioner using a socket wrench to relieve tension on the serpentine belt.
Remove the serpentine belt from the pulleys.
Inspect the belt for signs of wear (cracks, fraying).
If damaged, install a new belt by routing it around the pulleys according to the belt routing diagram.
Reapply tension using the tensioner.

5. Tighten Loose Components

Visually inspect and tighten any loose bolts or screws on the engine mounts or related components.
Ensure that any heat shields or brackets are firmly secured.

6. Reconnect Battery and Start Engine

Reconnect the negative terminal of the battery.
Start the engine and listen for any remaining noises.
