Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the engine is cool to prevent burns.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Thermostat

Tools Required: Socket set, gasket scraper, torque wrench.
Drain coolant from the radiator using the drain valve.
Remove the thermostat housing bolts and lift the housing off.
Take out the old thermostat and clean the mating surfaces.
Install the new thermostat (ensure it is oriented correctly) and replace the housing.
Torque the housing bolts to the manufacturer’s specifications.

3. Replace Water Pump (if necessary)

Tools Required: Socket set, pulley removal tool, gasket scraper.
Remove any components obstructing access to the water pump (e.g., belts).
Disconnect the hoses attached to the water pump.
Remove the water pump mounting bolts and carefully extract the pump.
Clean the mounting surface and install the new water pump with a new gasket.
Reattach hoses and components removed earlier.

4. Check and Replace Radiator Fan

Tools Required: Socket set, multimeter.
Inspect the fan for physical damage and test it for operation using a multimeter.
If faulty, detach the fan electrical connector and remove the mounting bolts.
Install the new radiator fan and reconnect the electrical connector.

5. Refill Coolant and Bleed System

Refill the radiator and coolant reservoir with the manufacturer-recommended coolant.
Start the engine and allow it to reach operating temperature, checking for air pockets.
Monitor the temperature gauge and check for leaks.
