If the seals are worn, replace them with new ones suitable for the pump model.
Ensure that the sealing surfaces are clean and free of debris.

4. Install the New or Repaired Pump

Position the power steering pump back into its mounting location.
Reinstall and torque the mounting bolts to the manufacturer's specifications (typically around 15-25 ft-lbs).
Reconnect the power steering fluid lines securely.

5. Refill and Bleed the Power Steering System

Refill the power steering fluid reservoir with the recommended fluid type for the Honda Pilot (Honda Power Steering Fluid).
Start the engine and turn the steering wheel from lock to lock multiple times to bleed any air from the system.
Check the fluid level and add more if necessary.
