Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is cool.
Tools Required: Socket set, screwdrivers, coolant catch pan, OBD-II scanner, multimeter.
Safety Warnings: Disconnect the battery before working on electrical components. Allow engine to cool before opening any cooling system components.

2. Check and Top Up Coolant

Remove the coolant reservoir cap.
If the coolant level is low, top it up with a 50/50 mixture of coolant and distilled water.
Replace the cap securely.

3. Replace Thermostat (if faulty)

Drain the coolant from the system into a catch pan.
Remove the thermostat housing by unscrewing the bolts.
Take out the old thermostat and replace it with a new one, ensuring proper orientation.
Reattach the thermostat housing and torque to manufacturer's specifications (typically around 10-15 Nm).
Refill the cooling system with the appropriate coolant mixture.

4. Check and Repair Cooling System Leaks

Inspect all hoses and connections for signs of wear, cracks, or leaks.
Replace any damaged hoses or components.
Tighten hose clamps if they are loose to prevent leaks.

5. Test and Replace Water Pump (if necessary)

Check for any coolant leaks from the water pump.
If the pump is noisy or leaking, remove the drive belt and unbolt the water pump.
Replace it with a new unit, ensuring to use new gaskets and sealant as needed.
Reattach the drive belt and ensure it is tensioned correctly.

6. Verify Radiator Fan Operation

Connect the battery and start the engine.
Allow the engine to reach operating temperature and observe if the radiator fan engages.
If the fan does not operate, test the fan and relay with a multimeter, replacing faulty parts as necessary.
