Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Worn Belts

Inspect the Serpentine Belt:
- Remove any covers obstructing the serpentine belt.
- Check for cracks, fraying, or signs of glazing.
Replace if Necessary:
- Use a belt tool to relieve tension and remove the old belt.
- Install the new serpentine belt following the routing diagram located near the engine bay.
- Reconnect battery and start the engine to check for proper operation.

3. Check and Replace Worn Hoses

Inspect Hoses:
- Look for cracks, leaks, or signs of wear on coolant and other hoses.
Replace if Necessary:
- Drain coolant if necessary and remove the damaged hose using pliers or hose clamps.
- Install the new hose, securing it with the appropriate clamps and refilling coolant to the required level.

4. Brake Inspection

Inspect Brake Components:
- Remove the wheel to access brake components.
- Check the brake pads and rotors for excessive wear or overheating signs.
Replace if Necessary:
- If the pads are worn, remove caliper bolts and replace the pads with new ones. Ensure proper torque specifications are followed.
- Inspect rotors for warping and replace if necessary.

5. Tire Inspection

Check Tire Condition:
- Inspect tires for uneven wear patterns or damage.
