Disconnect the power steering lines using a line wrench to avoid damaging the fittings.
Unbolt the power steering pump from its mounting bracket using a socket set.
Carefully lift the pump out of the engine bay.

4. Install the New Power Steering Pump

Position the new power steering pump in place and secure it with bolts, torqueing them to the manufacturer’s specifications (refer to service manual).
Reconnect the power steering lines, ensuring they are tight and leak-free.

5. Reinstall the Serpentine Belt

Route the serpentine belt back onto the power steering pump pulley and adjust the tensioner to secure it.
Double-check the alignment of the belt on all pulleys.

6. Refill Power Steering Fluid

Fill the power steering fluid reservoir with the recommended fluid (refer to owner’s manual).
Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.
