Solution

1. Preparation

Tools Required: Socket set, screwdrivers, OBD-II scanner, coolant pressure tester, multimeter, safety goggles, gloves.
Allow the engine to cool down before starting any work.
Disconnect the battery to prevent electrical shorts.

2. Check Coolant Levels

Remove the coolant reservoir cap and check the coolant level.
If low, top up with the appropriate coolant mixture (50/50 mix of distilled water and antifreeze).
Inspect for any visible leaks and repair as necessary.

3. Thermostat Inspection

Locate the thermostat housing and remove the bolts using a socket.
Remove the thermostat to inspect for damage or blockage.
Replace the thermostat if it is stuck closed or damaged.
Reinstall the thermostat with a new gasket, tightening to manufacturer specifications (typically 12-15 Nm).

4. Radiator and Hoses Inspection

Inspect the radiator for any signs of damage or blockages.
Check all hoses for wear, cracks, or leaks.
Replace any damaged hoses with new OEM parts.
Secure all connections to ensure proper sealing.

5. Radiator Fan Test

Reconnect the battery and start the engine.
Allow the engine to reach operating temperature and monitor the radiator fan operation.
If the fan does not engage, test the fan motor with a multimeter.
Replace the fan motor if it is non-functional.

6. Final Checks and Coolant System Pressure Test

Use a coolant pressure tester to check for leaks in the cooling system.
Pressurize the system and observe for any drops in pressure or visible leaks.
Refill the system with coolant if necessary and bleed any air from the system.
