Professional mechanic or engine builder installation recommended:

1. Drain the cooling system - Drain coolant from the radiator and engine block
2. Remove the fan and belt - Remove the fan shroud (if equipped), fan assembly, and drive belt
3. Access the water pump - Remove any components blocking access to the water pump
4. Remove the old water pump - Unbolt and remove the old pump; clean the mounting surface thoroughly
5. Inspect the mounting surface - Check for corrosion, pitting, or warping on the engine block mounting surface
6. Clean and prepare surface - Remove all old gasket material and sealant residue; use appropriate cleaning tools
7. Install the new gasket - Position the new gasket on the mounting surface; ensure proper alignment
8. Install the new water pump - Mount the new pump onto the gasket; hand-tighten bolts
9. Torque bolts to specification - Tighten bolts in a criss-cross pattern to manufacturer torque specifications
10. Reinstall fan and belt - Reinstall the fan assembly and drive belt; adjust belt tension to spec
11. Reconnect hoses - Attach all coolant hoses and secure with hose clamps
12. Refill with coolant - Fill the system with the correct coolant mixture (50/50 antifreeze/water or as specified)
13. Bleed the cooling system - Start the engine and bleed air from the system per manufacturer procedure
14. Check for leaks - Inspect all connections and the pump seal area for coolant leakage
15. Check operating temperature - Allow engine to reach operating temperature and verify gauge reading
