Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the engine is cool before starting work.
Disconnect the negative terminal of the battery for safety.

2. Replace Thermostat (if faulty)

Remove the thermostat housing:
- Use a socket set to remove bolts securing the thermostat housing.
- Carefully detach the housing and remove the old thermostat.
Install new thermostat:
- Place the new thermostat into the housing, ensuring it is seated correctly.
- Reattach the thermostat housing and tighten bolts to the manufacturer's specified torque (typically around 10-15 ft-lbs).
Reconnect battery.

3. Replace Water Pump (if faulty)

Remove serpentine belt:
- Use a wrench to relieve tension on the tensioner and slide the belt off the water pump pulley.
Remove water pump:
- Remove bolts securing the water pump using a socket set.
- Carefully detach the water pump and scrape off old gasket material from the engine block.
Install new water pump:
- Apply a new gasket or gasket maker to the new water pump.
- Position the new water pump onto the engine, securing it with bolts to the specified torque.
Reinstall serpentine belt.

4. Flush and Refill Coolant

Flush the cooling system:
- Connect a hose to the radiator's drain cock and drain old coolant into a container.
- Flush the system with water to remove contaminants.
Refill with proper coolant:
- Mix coolant with distilled water as per manufacturer specifications (typically 50/50).
- Fill the radiator and reservoir to the appropriate levels.

5. Verify Radiator Fan Operation

Reconnect battery and start the engine:
- Allow the engine to reach operating temperature and verify that the radiator fan activates properly.
