Solution

1. Preparation

Tools Required: Socket set, screwdrivers, OBD-II scanner, multimeter, coolant tester
Ensure the engine is cool to avoid burns.
Disconnect the battery to prevent electrical shorts during inspection.

2. Inspect and Replace Worn Components

Serpentine and Accessory Belts
1. Locate the serpentine belt tensioner and relieve tension using a wrench.
2. Remove the belt and inspect for cracks, fraying, or signs of melting.
3. Replace with a new belt if damage is noted, ensuring proper routing.
Hoses
1. Check all rubber hoses in the engine bay for signs of wear or melting.
2. Replace any damaged hoses with OEM or quality aftermarket replacements.

3. Address Fluid Leaks

Coolant and Oil Leaks
1. Inspect the engine and undercarriage for fluid leaks.
2. Fix any leaking gaskets or seals; replace fluids as necessary.
3. Use a coolant tester to check for proper coolant levels and quality.

4. Cooling System Check

Radiator and Thermostat Inspection
1. Inspect the radiator for blockages or damage.
2. Test the thermostat operation by checking if it opens and closes correctly at the specified temperature.
3. Replace the thermostat if faulty.

5. Exhaust System Examination

Inspect for Leaks
1. Check the exhaust manifold and pipes for cracks or loose connections.
