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 before working on electrical components.

2. Address Fluid Leaks

Identify and clean any fluid leaks found during inspection.
For oil leaks: Replace any damaged gaskets or seals (e.g., valve cover gasket, oil pan gasket).
For coolant leaks: Replace any defective hoses or the water pump as necessary.

3. Replace Worn Belts or Hoses

Remove the serpentine belt if damaged.
- Use a socket set to loosen the tensioner and slide the belt off.
Install a new belt, ensuring it is properly aligned with all pulleys.
Inspect and replace any damaged hoses, using hose clamps to secure them firmly.

4. Brake System Inspection and Repair

Remove the wheel to access brake components.
- Use a socket set to remove the lug nuts and take off the wheel.
Inspect brake pads; replace any that are worn down to the indicators.
Check brake rotors for warping or overheating signs; replace if necessary.

5. Address Overheating Issues

If the coolant level is low, fill it with the appropriate coolant type.
Inspect the radiator and replace any damaged components.
Test the thermostat by placing it in boiling water to see if it opens. Replace if faulty.
