Solution

1. Preparation

Gather required tools and parts.
Ensure the engine is cool before beginning work to avoid burns.
Disconnect the battery to prevent electrical shorts.

2. Coolant System Inspection

Sub-steps:
- Remove the coolant reservoir cap and check the coolant condition; replace if dirty or contaminated.
- Inspect coolant hoses for cracks or bulges; replace if necessary.

3. Replace Thermostat

Sub-steps:
- Drain the coolant from the system using a drain pan.
- Remove the thermostat housing by unscrewing the bolts (torque value: 15-20 ft-lbs).
- Remove the old thermostat and clean the mating surfaces.
- Install the new thermostat, ensuring it is oriented correctly.
- Reattach the thermostat housing and secure it with bolts.

4. Replace Water Pump (if necessary)

Sub-steps:
- Drain the coolant completely from the system.
- Remove any components obstructing access to the water pump (e.g., fan shroud, serpentine belt).
- Unscrew the water pump mounting bolts (torque value: 20-25 ft-lbs) and carefully remove the pump.
- Clean the mounting surface on the engine block.
- Install the new water pump, ensuring the gasket is properly seated.
- Reattach all components removed and refill the cooling system with the appropriate coolant type.

5. Radiator and Cooling Fan Check

Sub-steps:
- Clean the radiator fins with compressed air to remove debris.
- Test the cooling fan operation by turning on the vehicle and checking if the fan activates at the appropriate temperature.
- Replace the fan if it does not operate correctly.
