Remove the coolant reservoir cap.
Add coolant to the required level if low; use a mixture of 50% antifreeze and 50% distilled water.

3. Replace Thermostat (if faulty)

Tools Required: Socket set, torque wrench, gasket scraper.
Remove the thermostat housing by unscrewing the bolts.
Take out the old thermostat and compare it with the new one.
Clean the mating surfaces of the thermostat housing and engine block.
Install the new thermostat, ensuring it's positioned correctly.
Reattach the housing and torque the bolts to the manufacturer's specifications.

4. Inspect and Clean Radiator

Remove any debris obstructing the front of the radiator.
Use a garden hose to flush the radiator with water, ensuring it flows freely.
Replace the radiator if damaged or leaking.

5. Replace Radiator Fan (if faulty)

Disconnect the electrical connector from the fan.
Remove the fan assembly from the radiator by unscrewing it.
Install the new fan assembly and reconnect the electrical connector.
