Installation Notes

Professional installation recommended. Proper steering system preparation is essential:

  1. Relieve system pressure – Cycle the steering wheel several times with the engine off to relieve pressure
  2. Drain power steering fluid – Drain the fluid from the power steering reservoir
  3. Remove the drive belt – Loosen and remove the drive belt from the pump pulley
  4. Disconnect hoses – Carefully disconnect the pressure and return hoses from the pump
  5. Remove the old pump – Unbolt and remove the power steering pump from the engine bracket
  6. Remove the pulley – If required, remove the pulley from the old pump (if not transferring to the new pump)
  7. Clean the mounting area – Clean the engine mounting bracket and surrounding areas
  8. Prepare the new pump – Install the pulley onto the new pump if not pre-installed
  9. Transfer fittings – Transfer any necessary fittings from the old pump to the new pump
  10. Prime the new pump – Fill the new pump with clean power steering fluid before installation
  11. Install the new pump – Position the new pump and install mounting bolts
  12. Torque to specifiion – Tighten bolts to manufacturer specifiion
  13. Reconnect hoses – Reconnect the pressure and return hoses with new O-rings/seals
  14. Reinstall the drive belt – Install the drive belt and adjust tension to manufacturer specifiion
  15. Refill with fluid – Fill the reservoir with the correct type of power steering fluid
  16. Bleed the system – Start the engine and turn the steering wheel lock-to-lock several times to bleed air
  17. Check fluid level – Recheck and top up the fluid level as needed
  18. Check for leaks – Inspect all connections for fluid leakage
  19. Test drive – Road-test the vehicle to verify smooth, responsive steering operation
