Professional installation recommended. Proper cooling system service is critical:

1. Allow engine to cool - Ensure the engine is completely cool before beginning work
2. Disconnect battery - Disconnect the negative battery cable before beginning work
3. Drain coolant - Drain the cooling system completely
4. Remove the drive belt - Loosen and remove the drive belt from the water pump pulley
5. Remove the fan shroud and fan - Remove the fan and shroud for access to the water pump
6. Remove the old water pump - Unbolt and carefully remove the water pump from the engine block
7. Remove old gasket material - Clean the engine block mounting surface, removing all old gasket material
8. Inspect the cooling system - Check the thermostat, hoses, and radiator for wear or damage
9. Clean mounting surface - Thoroughly clean the engine block mounting surface
10. Prepare the new pump - Inspect the new pump and verify it matches the original
11. Install the new gasket - Position a new gasket on the engine block
12. Install the new water pump - Position the new pump and secure with mounting bolts
13. Torque to specifiion - Tighten bolts to manufacturer specifiion in a crisscross pattern
14. Reinstall fan and shroud - Reinstall the fan, shroud, and drive belt
15. Adjust belt tension - Adjust the drive belt tension to manufacturer specifiion
16. Refill coolant - Refill the cooling system with the correct type and mixture of coolant
17. Bleed air from the system - Bleed air from the cooling system as per the service manual
18. Reconnect battery - Reconnect the negative battery cable
19. Check for leaks - Start the engine and inspect for any coolant leakage around the pump
20. Verify operation - Allow the engine to reach operating temperature and verify proper cooling system operation
