Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, coolant tester.
Ensure the engine is cool before beginning work to prevent burns.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Coolant Level Check

Remove the coolant reservoir cap carefully.
If coolant is low, add manufacturer-recommended coolant to the proper level.
Inspect for leaks and top off as necessary.

3. Thermostat Replacement

Tools Required: Socket set, torque wrench.
Locate the thermostat housing.
Remove the bolts securing the thermostat housing.
Carefully lift the housing and replace the old thermostat with a new one.
Ensure the gasket is seated properly and reassemble the housing, tightening bolts to the manufacturer's torque specifications.

4. Radiator and Hoses Inspection

Inspect all hoses connected to the radiator for cracks or weakness.
Replace any damaged hoses using a hose clamp tool.
Clean the radiator fins with compressed air to remove any debris blocking airflow.

5. Cooling Fan and Water Pump Check

Test the cooling fan operation by turning on the air conditioning.
If the fans do not engage, check the fan relay and replace if defective.
Inspect the water pump for leaks and ensure it is functioning properly; replace if necessary.
