Solution

1. Preparation

Gather tools and parts needed before starting.
Allow the engine to cool down completely before beginning the repair.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Coolant Level and Condition Check

Locate the coolant reservoir and remove the cap.
Inspect the coolant for clarity and level; top off with the manufacturer-recommended coolant if necessary.
If the coolant appears contaminated, proceed to flush the cooling system.

3. Radiator and Cooling System Inspection

Visually inspect the radiator for any visible leaks, cracks, or obstructions.
Check hoses connected to the radiator for bulges, cracks, or wear.
If leaks are found, replace the affected hoses or radiator.

4. Electric Cooling Fans Check

Start the vehicle and let it idle until the temperature gauge approaches the operating range.
Observe the cooling fans; they should activate at a certain temperature.
If the fans do not engage, test the fan motors with a multimeter and replace if faulty.

5. Thermostat Inspection

Locate the thermostat housing and remove it.
Inspect the thermostat for proper function; it should open at the specified temperature.
If faulty, replace it with a new thermostat ensuring correct orientation.

6. Water Pump Assessment

Check for any signs of leakage around the water pump or unusual noise during operation.
If the water pump does not circulate coolant effectively, it should be replaced.
Refill the cooling system with the appropriate coolant after replacing any components.
