Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Replace Thermostat

Tools Required: Socket set, torque wrench, gasket scraper, new thermostat, and gasket.
Remove the thermostat housing by unscrewing the bolts with a socket wrench.
Carefully lift the thermostat out of the housing, noting its orientation.
Clean the mating surfaces on the housing and engine block with a gasket scraper.
Install the new thermostat in the same orientation as the old one.
Apply a new gasket to the thermostat housing and reattach it, tightening the bolts to the manufacturer's specified torque.

3. Inspect/Replace Water Pump

Tools Required: Socket set, screwdrivers, new water pump, gasket, and sealant.
Drain the coolant from the radiator by opening the drain plug.
Remove the serpentine belt from the water pump pulley.
Unscrew and detach the water pump from the engine block.
Clean the old gasket material from the mounting surface.
Install the new water pump with a new gasket and secure it using the appropriate torque specifications.
Reinstall the serpentine belt.

4. Flush and Refill Cooling System

Tools Required: Coolant funnel, coolant, and hoses.
Flush the cooling system using a flush kit or by running clean water through the system until it runs clear.
Refill the system with the recommended coolant type and mixture.
Bleed the cooling system to remove any air pockets.
