Solution

1. Preparation

Tools Required: Socket set, coolant pressure tester, OBD-II scanner, thermometer.
Ensure the engine is cool before starting work. Disconnect the battery to avoid electrical issues.

2. Coolant Replacement

Sub-steps:
1. Place a drain pan under the radiator.
2. Open the radiator drain valve to let the old coolant flow out completely.
3. Close the drain valve once all coolant is drained.
4. Flush the cooling system with water by filling the radiator and running the engine for a few minutes, then drain again.
5. Refill the cooling system with the appropriate coolant mixture (50% coolant, 50% distilled water).

3. Thermostat Replacement

Sub-steps:
1. Locate the thermostat housing; it typically connects the upper radiator hose to the engine.
2. Remove the bolts securing the housing with a socket set.
3. Carefully remove the housing and the old thermostat.
4. Clean the mating surfaces on the engine and housing.
5. Install the new thermostat, ensuring it is oriented correctly.
6. Reattach the thermostat housing and torque the bolts to the manufacturer's specifications.

4. Water Pump Inspection/Replacement

Sub-steps:
1. If the water pump shows signs of failure, disconnect the serpentine belt.
2. Remove the bolts securing the water pump and detach it from the engine.
3. Clean the mounting surface.
4. Install the new water pump, ensuring a proper gasket seal.
5. Reattach the serpentine belt, ensuring it is correctly routed.

5. Radiator Fan Check/Replacement

Sub-steps:
1. Test the radiator fan by applying direct power to the fan motor to see if it operates.
2. If the fan does not operate, disconnect the battery and remove any covers to access the fan.
3. Replace the fan if it does not function correctly.
