Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Check Coolant Level

Open the coolant reservoir cap slowly to release pressure.
If low, top off with the manufacturer-recommended coolant type.
Inspect for any visible signs of leaks around hoses and fittings.

3. Inspect and Replace Cooling Fan

Tools Required: Socket set, multimeter.
Disconnect the wiring harness from the cooling fan.
Use a multimeter to test the fan motor for continuity. Replace if faulty.
Reinstall the new fan and reconnect the electrical harness.

4. Inspect and Replace Thermostat

Tools Required: Socket set, screwdriver, gasket scraper.
Locate the thermostat housing and disconnect any hoses attached.
Remove the housing bolts and take out the thermostat.
Clean the mating surfaces and install a new thermostat with a new gasket.
Reattach the housing and hoses securely.

5. Pressure Test the Cooling System

Use a cooling system pressure tester to check for leaks.
If leaks are found, replace the faulty components (hoses, radiator, etc.).
Refill the cooling system with the appropriate coolant.
