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

3. Replace Thermostat (if faulty)

Tools Required: Socket set, gasket scraper, torque wrench
Drain the coolant from the radiator.
Remove the thermostat housing by loosening bolts with a socket wrench.
Take out the old thermostat and gasket.
Clean the mating surfaces with a gasket scraper.
Install the new thermostat with a new gasket, ensuring it is oriented correctly.
Torque the bolts to the manufacturer's specifications (typically around 15-20 lb-ft).
Refill the cooling system with the appropriate coolant.

4. Inspect and Replace Water Pump (if necessary)

Tools Required: Socket set, coolant catch pan, new water pump, gasket
Drain the coolant from the system.
Remove the serpentine belt by releasing tension using a belt tensioner tool.
Unbolt the water pump from the engine block and remove it.
Clean the mounting surface on the engine block.
