Solution

1. Preparation

Gather tools and parts required.
Ensure the engine is cool before starting work.
Disconnect the negative battery cable to prevent electrical issues.

2. Replace Thermostat

Sub-steps:
1. Drain the coolant from the radiator into a suitable container.
2. Remove the thermostat housing bolts using a socket set.
3. Lift off the thermostat housing and remove the old thermostat.
4. Clean the mating surfaces of the housing and engine block.
5. Install the new thermostat ensuring correct orientation.
6. Reattach the thermostat housing and tighten bolts to manufacturer specifications (typically 89 in-lbs).

3. Replace Water Pump (if necessary)

Sub-steps:
1. Remove the serpentine belt using a belt tensioner tool.
2. Detach the water pump bolts and remove the pump from the engine block.
3. Clean the mounting surface on the engine.
4. Install the new water pump with a new gasket or sealant as required.
5. Torque the water pump bolts to manufacturer specifications.

4. Refill Coolant

Sub-steps:
1. Refill the radiator and reservoir with the appropriate type of coolant (usually a 50/50 mix of antifreeze and water).
2. Start the engine and allow it to reach operating temperature while checking for leaks.
3. Top off the coolant as needed.
