Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool completely before beginning work.

2. Coolant Replacement

Drain the old coolant: Open the drain valve at the bottom of the radiator and allow the coolant to flow into a suitable container.
Flush the system: Use a radiator flush product per manufacturer instructions to remove any debris or deposits.
Refill with new coolant: Mix the appropriate type of coolant with water (consult owner's manual for specifications) and fill the radiator and reservoir to the correct level.

3. Thermostat Replacement

Remove the thermostat housing: Disconnect hoses and bolts holding the housing in place.
Extract the thermostat: Take out the old thermostat and replace it with a new one, ensuring it is positioned correctly.
Reassemble housing: Reattach the housing and tighten the bolts to the manufacturer's specified torque.

4. Radiator and Hose Inspection

Inspect and replace damaged components: If hoses show signs of wear or leaks, replace them.
Clean the radiator: Remove any debris or obstructions from the radiator fins.

5. Fan and Water Pump Check

Test the radiator fan: Connect the battery to verify fan operation when power is supplied.
Check the water pump: If the pump is not circulating coolant properly, replace it following the manufacturer’s guidelines.
