Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool completely before starting work.

2. Replace Thermostat (if faulty)

Drain Coolant: Place a drain pan under the radiator and open the drain valve to let coolant flow out.
Remove Thermostat Housing: Use a socket set to remove the bolts securing the thermostat housing.
Replace Thermostat: Take out the old thermostat and install a new one, ensuring the correct orientation.
Reinstall Housing: Torque the thermostat housing bolts to the manufacturer’s specifications (consult the service manual for the exact value).
Replenish Coolant: Close the drain valve and refill the system with the appropriate coolant mixture.

3. Repair or Replace Radiator Fan (if faulty)

Inspect Wiring and Fuses: Check the fan wiring and related fuses for damage or disconnection.
Remove Fan Assembly: Disconnect electrical connectors and remove any mounting bolts to take out the fan.
Test Fan Operation: Connect the fan directly to a power source to verify it operates.
Replace Fan: If the fan doesn't operate, install a new fan assembly and secure it with bolts.

4. Coolant System Flush

Flush System: Use a coolant flush solution and follow the manufacturer’s instructions to clean out the system.
Rinse: After flushing, rinse the system with clean water to remove any remaining flush solution.
Fill with New Coolant: Refill the system with the correct type of coolant to the specified level.
