  4. Disconnect hoses - note positions (inlet, outlet, bypass)
  5. Unbolt old water pump - remove mounting bolts. Note bolt lengths and positions
  6. Clean mating surface - on engine block. Remove old gasket material. Do not scratch surface
  7. Compare new pump with old - check mounting, port locations, and pulley fit
  8. Install new gasket - position on block (some gaskets have adhesive backing)
  9. Install new water pump - place onto studs/bolts. Tighten bolts in sequence to specification (typically 20-30 Nm). Do not overtighten
  10. Reconnect hoses - use new hose clamps if needed
  11. Reinstall fan and fan clutch - torque bolts to specification
  12. Reinstall drive belt - ensure correct routing and tension
  13. Refill coolant - use recommended type (e.g., long-life or heavy-duty diesel coolant). Fill slowly to avoid air pockets
  14. Bleed the cooling system - run engine with heater on high, add coolant as needed. Use bleed valve if equipped
  15. Check for leaks - inspect pump gasket and hose connections
  16. Test drive - monitor engine temperature gauge
