Solution

1. Preparation

Ensure the engine is cool before starting repairs.
Gather all necessary tools and parts.
Disconnect the negative battery terminal for safety.

2. Coolant Level Check

Tools Required: Coolant funnel
Check the coolant level in the reservoir; top off with manufacturer-recommended coolant if low.
Inspect the radiator cap for damage; replace if necessary.

3. Replace Thermostat (if faulty)

Tools Required: Socket set, torque wrench, gasket scraper
Drain the coolant from the radiator into a clean container.
Remove the thermostat housing bolts and take off the housing.
Remove the old thermostat and clean the mating surfaces.
Install the new thermostat, ensuring it is oriented correctly.
Reattach the thermostat housing and torque to the manufacturer specification.
Refill the cooling system with the appropriate coolant mixture.

4. Replace Water Pump (if defective)

Tools Required: Socket set, torque wrench, coolant drain pan
Drain the coolant from the system.
Remove the serpentine belt by loosening the tensioner.
Disconnect the hoses attached to the water pump.
Remove the water pump mounting bolts and take out the pump.
Install the new water pump, ensuring all gaskets are in good condition.
Reattach hoses and belt, and refill the cooling system.

5. Test Radiator Fan

Tools Required: Multimeter
With the engine running, check the voltage at the fan connector using a multimeter.
If the fan does not operate, replace the fan motor.
