Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, coolant pressure tester, multimeter.
Ensure the vehicle is on a flat surface and the engine is cool before starting.
Disconnect the battery to prevent electrical shorts while working on the cooling system.

2. Coolant Level Check

Locate the coolant reservoir and visually inspect the fluid level.
If low, top off with the recommended coolant type (typically a 50/50 mix of antifreeze and distilled water).
Safety Warning: Never open the radiator cap when the engine is hot to avoid burns.

3. Inspect Radiator and Components

Remove any debris blocking the front of the radiator.
Check the radiator for any signs of damage or corrosion.
Inspect hoses for leaks, cracks, or soft spots; replace any damaged hoses.

4. Test Radiator Fans

Use a multimeter to check the voltage supply to the radiator fans.
If the fans are not operating, check the fan relay and fuses.
Replace any faulty components and ensure the fans are securely mounted.

5. Replace Thermostat (if necessary)

Drain the coolant from the radiator using a coolant drain pan.
Remove the thermostat housing and take out the old thermostat.
Install a new thermostat ensuring it is oriented correctly.
Reassemble the housing and refill the coolant to the proper level.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the engine and allow it to reach operating temperature while monitoring the temperature gauge.
Check for leaks and ensure that the fans engage when the engine reaches high temperatures.
