If the radiator is damaged, remove it by unscrewing the mounting bolts.
Disconnect the inlet and outlet hoses.
Install the new radiator and reconnect hoses, ensuring a tight fit.

3.3 Water Pump

If the water pump is leaking, remove the serpentine belt.
Unbolt the water pump and detach it from the engine block.
Clean the mounting surface and install the new pump with a new gasket.

4. Refill the Coolant

Close the radiator drain valve.
Refill the cooling system with the recommended coolant type, ensuring no air is trapped in the system.
Check the manufacturer’s specifications for the coolant mixture ratio.

5. Testing

Reconnect the battery.
Start the engine and let it run for a few minutes.
Check for leaks around the repaired areas while the engine is running.
