Solution

1. Preparation

Gather tools and parts necessary for inspection and repair.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Safety gear: gloves and safety glasses.

2. Inspect and Replace Engine Belts

Sub-steps:
1. Open the hood and visually inspect all engine belts for damage.
2. If any belts are damaged, loosen the tensioner using a ratchet and socket.
3. Remove the damaged belt and replace it with a new one, ensuring proper routing.
4. Tighten the tension to manufacturer specifications (usually around 20-25 Nm).

3. Check and Replace Tires

Sub-steps:
1. Inspect each tire for uneven wear, bulges, or objects embedded in the tread.
2. If tires are worn out or damaged, replace them with new tires of the correct size.
3. Ensure all tires are inflated to the recommended PSI as specified in the owner’s manual.

4. Inspect Electrical Components

Sub-steps:
1. Locate and inspect wiring harnesses for any signs of melting or damage.
2. If damaged wires are found, replace them with appropriate gauge wiring.
3. Check fuse boxes and relays for any signs of overheating or failure.
