Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Drive Belts

Tools Required: Socket set, belt tensioner tool.
Remove the engine cover (if applicable) to access the drive belts.
Inspect belts for signs of wear, cracks, or melting.
If damaged, loosen the belt tensioner and remove the old belt.
Install the new belt, ensuring proper alignment with pulleys, and tighten the tensioner according to manufacturer specifications.

3. Check and Replace Hoses

Tools Required: Pliers, hose clamps, coolant.
Inspect hoses for signs of wear or leaks.
If any hoses are cracked or melted, remove the clamps and the old hose.
Install the new hose, ensuring a secure fit and reattach the clamps.

4. Brake Component Inspection

Tools Required: Jack, jack stands, socket set, torque wrench.
Safely raise the vehicle and secure it on jack stands.
Remove the wheel to access the brake assembly.
Inspect brake pads, rotors, and calipers for signs of excessive wear or overheating.
Replace any worn or damaged components, ensuring proper torque specifications during reassembly.

5. Electrical Component Review

Tools Required: Multimeter.
Inspect wiring for any signs of damage, particularly near the engine or wheel wells.
Use a multimeter to check for shorts or grounding issues.
Repair or replace damaged wiring as needed.
