Solution

1. Preparation

Tools Required: OBD-II scanner, coolant pressure tester, infrared thermometer, basic hand tools (sockets, wrenches).
Ensure the engine is cool before starting any repairs to avoid burns.

2. Replace Thermostat (if faulty)

Sub-steps:
1. Drain the coolant from the radiator using a drain pan.
2. Disconnect the negative battery terminal.
3. Locate the thermostat housing and remove the bolts using a socket.
4. Carefully remove the thermostat and gasket.
5. Install the new thermostat with a new gasket, ensuring correct orientation.
6. Reinstall the thermostat housing and torque the bolts to the manufacturer's specifications (usually around 15-20 lb-ft).
7. Refill the coolant system with the proper coolant mixture.

3. Repair or Replace Cooling System Components

Sub-steps:
1. If leaks are found, replace damaged hoses or the radiator as necessary.
2. For malfunctioning cooling fans, test the fan relay and wiring; replace the fan motor if defective.
3. Inspect and clean the radiator if debris is blocking airflow.
4. Ensure the water pump is functioning properly; replace if it shows signs of failure (noise, leaks).
