Solution

1. Regular Maintenance

Coolant Flush:
- Drain the old coolant by opening the radiator drain valve.
- Flush the system with a coolant flush product, following the manufacturer’s instructions.
- Refill with the recommended type and mixture of coolant (usually a 50/50 mix of antifreeze and distilled water).
Inspect and Replace Hoses:
- Check all hoses for cracks, bulges, or leaks.
- Replace any damaged hoses using appropriate clamps for secure fittings.

2. Thermostat Inspection

Remove Thermostat:
- Drain a small amount of coolant to lower the level below the thermostat.
- Remove the thermostat housing bolts and detach the housing.
- Take out the thermostat and inspect for proper operation; it should open at the specified temperature.
Replace If Necessary:
- If the thermostat is faulty, replace it with a new one, ensuring the gasket is sealed properly during reinstallation.

3. Water Pump Inspection

Check for Leaks:
- Inspect the water pump for coolant leaks or signs of wear.
Replace if Faulty:
- If leaks are present, remove the old water pump by loosening the mounting bolts and disconnecting hoses.
- Install the new water pump, ensuring all bolts are torqued to the manufacturer’s specifications.

4. Radiator and Fan Maintenance

Inspect Radiator:
- Check for debris blocking airflow through the radiator. Clean as necessary using compressed air or a soft brush.
Radiator Fan Check:
- Start the engine and observe the fan operation; it should engage when the engine reaches operating temperature.
- If the fan is not working, replace the fan motor and check the relay.
