Tools Required: Socket set, torque wrench, gasket scraper
Remove the bolts securing the thermostat housing.
Carefully detach the housing and remove the old thermostat.
Clean the mating surfaces on the engine and thermostat housing.
Install the new thermostat ensuring the correct orientation.
Reattach the thermostat housing and torque the bolts to manufacturer specifications.

3. Inspect and Replace Water Pump (if necessary)

Tools Required: Socket set, coolant drain pan, gasket scraper
Drain coolant from the radiator into the drain pan.
Remove the drive belt from the water pump.
Unbolt the water pump from its mounting.
Remove the old pump and clean the surface.
Install the new water pump with a new gasket and torque to the specified value.
Reinstall the drive belt.

4. Flush Cooling System

Tools Required: Garden hose, coolant flush kit (optional)
Connect a garden hose to the radiator and run water through it until it runs clear, ensuring all contaminants are removed.
Refill the radiator with the appropriate coolant mixture as specified by the manufacturer.

5. Reassemble and Test

Reconnect the battery.
Start the engine and allow it to reach operating temperature while monitoring the temperature gauge.
Check for leaks around the thermostat and water pump.
