Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the engine is cool before starting work.
Disconnect the battery to prevent electrical shorts.

2. Replace Thermostat

Locate the thermostat: Follow the upper radiator hose to find the thermostat housing.
Remove the housing: Use a socket set to remove the bolts securing the thermostat housing. Carefully lift it off.
Replace the thermostat: Remove the old thermostat and clean the mating surfaces. Install the new thermostat, ensuring it is seated correctly.
Reattach the housing: Secure the thermostat housing with bolts and torque them to the manufacturer's specifications (typically around 15-20 ft-lbs).

3. Inspect/Replace Water Pump

Remove the serpentine belt: Use a wrench to relieve tension on the belt tensioner and slip the belt off the pulleys.
Disconnect hoses: Remove the inlet and outlet hoses from the water pump, noting their positions.
Remove the water pump: Unscrew the mounting bolts and carefully pull the water pump off. Clean any gasket remnants from the engine block.
Install new water pump: Position the new pump and secure it with bolts. Torque to specified values (usually 20-30 ft-lbs).
Reconnect hoses and serpentine belt: Ensure all connections are tight and properly seated.

4. Refill Coolant

Fill the radiator: Use the recommended coolant mixture (typically 50/50 antifreeze and distilled water).
Bleed the system: Start the engine and let it reach operating temperature. Check for air bubbles in the reservoir and top off coolant as needed.

5. Reconnect Battery

Reconnect the battery terminals and ensure they are tight.
