Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool to avoid burns.
Disconnect the battery.

2. Coolant Flush and Replacement

Sub-steps:
1. Place a drain pan under the radiator.
2. Open the radiator drain valve and allow the old coolant to drain completely.
3. Close the drain valve and refill the system with a manufacturer-recommended coolant mixture.
4. Start the engine and let it run until the thermostat opens, adding coolant as necessary to eliminate air pockets.

3. Thermostat Replacement (if faulty)

Sub-steps:
1. Remove the thermostat housing bolts using a socket set.
2. Lift off the housing and remove the old thermostat.
3. Clean the mating surfaces on the engine and housing.
4. Install the new thermostat with the correct orientation.
5. Reattach the thermostat housing and torque the bolts to the manufacturer specifications.

4. Water Pump Inspection/Replacement (if necessary)

Sub-steps:
1. Remove the serpentine belt by releasing tension using a belt tensioner tool.
2. Disconnect hoses connected to the water pump.
3. Remove bolts securing the water pump and take out the pump.
4. Clean the mounting surface and install the new water pump with a new gasket.
5. Reconnect hoses and serpentine belt.

5. Radiator Fan Check

Sub-steps:
1. Inspect the fan motor for electrical continuity using a multimeter.
2. If faulty, disconnect the fan connector and remove the fan assembly.
3. Install a new radiator fan and reconnect the wiring harness.
