Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Tire Inspection and Replacement (if necessary)

Sub-steps:
1. Inspect all tires for wear patterns, bulges, or damage.
2. Check tire pressure using a tire pressure gauge, and inflate to the manufacturer’s recommended PSI.
3. If tires are worn or damaged, replace them with new ones.

3. Brake Inspection and Service

Sub-steps:
1. Remove the wheels to access the brake components.
2. Inspect brake pads for excessive wear; replace if less than 3mm thick.
3. Check brake rotors for warping or excessive heat marks; replace if necessary.
4. Ensure calipers are functioning properly without sticking.

4. Engine Belt Inspection and Replacement (if necessary)

Sub-steps:
1. Locate the serpentine belt; visually inspect for cracks or fraying.
2. Check the tension on the belt; replace if loose or worn.
3. If a new belt is needed, remove the old belt by loosening the tensioner pulley and install the new belt according to the routing diagram.

5. Clean Up and Reassemble

Sub-steps:
1. Clean any debris or residue from the inspected areas.
2. Reinstall the wheels and torque lug nuts to the manufacturer’s specifications.
3. Reconnect the battery and start the vehicle to ensure all systems are functioning correctly.
