Solution

1. Preparation

Gather tools: OBD-II scanner, coolant pressure tester, socket set, and multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Refill Coolant

Open the coolant reservoir cap and check the fluid level.
If low, add the appropriate coolant mixture (50/50 water and antifreeze) until it reaches the proper level.
Replace the cap securely.

3. Repair or Replace Leaking Components

Radiator Inspection
- Remove any debris obstructing airflow to the radiator.
- If leaks are found, replace the radiator as necessary.
- Tools: Socket set for mounting bolts.
Hose Inspection
- Inspect all coolant hoses for cracks or leaks. Replace any damaged hoses.
- Tools: Hose clamp pliers.

4. Thermostat Replacement

Locate the thermostat housing, usually near the engine block.
Remove the thermostat housing bolts using a socket set.
Replace the old thermostat with a new one, ensuring the gasket is in place.
Torque the bolts to the manufacturer’s specifications (usually around 89 in-lbs).

5. Radiator Fan Testing

Connect the multimeter to the radiator fan connector.
Start the engine and let it idle; the fan should engage when the temperature reaches a certain threshold.
If the fan does not operate, replace the fan motor.
