Solution

1. Preparation

Gather tools and safety equipment.
Ensure the engine is cool before beginning repairs.
Disconnect the battery to prevent electrical shorts.

2. Replace Coolant

Drain the existing coolant by opening the radiator drain valve.
Flush the cooling system with a coolant flush solution and water if necessary.
Refill with the manufacturer-recommended coolant mixture (typically 50% coolant and 50% distilled water).

3. Inspect and Replace Thermostat

Remove the thermostat housing by unscrewing the bolts with a socket set.
Remove the old thermostat and clean the mating surfaces.
Install the new thermostat with the correct orientation (usually with the spring side facing the engine).
Reattach the thermostat housing and torque bolts to the manufacturer’s specifications.

4. Check and Replace Water Pump (if necessary)

Remove the serpentine belt by loosening the belt tensioner.
Unscrew the water pump mounting bolts and remove the old water pump.
Clean the mounting surface on the engine block.
Install the new water pump, ensuring the gasket is properly aligned, and torque the bolts as specified.

5. Test Cooling Fans

Reconnect the battery and start the engine.
Turn on the AC to check if the cooling fans engage.
If fans do not operate, check the fan relay and fuses, replacing any faulty components.
