Solution

1. Preparation

Tools Required: Socket set, screwdrivers, coolant refill container, OBD-II scanner.
Safety Warnings: Allow the engine to cool down completely before working on the cooling system. Wear gloves and safety glasses.

2. Check and Refill Coolant

Locate the coolant reservoir and ensure it is filled to the recommended level.
If necessary, mix the appropriate coolant (50/50 mix of antifreeze and distilled water) and fill the reservoir and radiator.

3. Inspect and Replace Thermostat (if faulty)

Disconnect the negative battery terminal.
Drain coolant from the radiator into a container.
Remove the thermostat housing bolts using a socket set.
Take out the thermostat and inspect for proper opening.
Replace with a new thermostat that matches OEM specifications.
Reassemble the housing and refill the coolant.

4. Inspect and Repair Leaks

Check all hoses connected to the radiator and the engine for cracks or leaks.
Replace any damaged hoses with new OEM parts, tightening the clamps securely.
If the radiator is leaking, replace it. Remove the old radiator, install the new one, and reconnect all hoses.

5. Test Radiator Fan Operation

Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature.
Observe whether the radiator fan activates as the temperature gauge rises. If it does not, check the fan relay and fuses.
Replace any faulty components.
