Tools Required: Socket set, torque wrench, gasket scraper.
Steps:
1. Locate the thermostat housing; remove the bolts using the socket set.
2. Carefully extract the old thermostat from the housing.
3. Clean the mating surfaces using a gasket scraper to remove any old gasket material.
4. Install the new thermostat ensuring it is oriented correctly.
5. Reattach the housing and tighten the bolts to the manufacturer's torque specifications.

4. Inspect and Replace Water Pump (if necessary)

Tools Required: Socket set, wrench set, coolant catch pan.
Steps:
1. Drain the coolant into a catch pan by removing the drain plug from the radiator.
2. Disconnect the hoses attached to the water pump.
3. Unbolt the water pump using the socket set and remove it from the engine.
