Solution

1. Preparation

Tools Required: OBD-II scanner, coolant, funnel, socket set, thermometer, safety glasses, gloves
Allow the engine to cool down completely before starting any work.
Disconnect the battery to prevent any electrical issues.

2. Check Coolant Level

Use a funnel to add coolant to the reservoir if low.
Inspect for cracks or leaks in the reservoir.

3. Inspect and Replace Thermostat

Tools Required: Socket set, gasket scraper
Remove the thermostat housing bolts and take off the housing.
Remove the old thermostat and clean the mating surfaces.
Install the new thermostat and gasket, ensuring proper orientation.
Reattach the housing and torque bolts to the manufacturer’s specifications.

4. Inspect Radiator and Hoses

Look for signs of wear or damage on the radiator and hoses.
Replace any damaged hoses or the radiator if leaks are found.

5. Test Radiator Fans

Start the engine and let it reach operating temperature.
Check if the radiator fans engage when the engine is hot.
Replace any faulty fans or fuses if necessary.

6. Flush Cooling System (if necessary)

Drain the old coolant from the radiator and engine block.
Flush the system with clean water or a cooling system cleaner.
Refill with the manufacturer-recommended coolant mixture.
