Disconnect the power steering lines from the pump using a wrench; be prepared for some fluid spillage.
Unbolt the pump from its mounting bracket.
Install the new power steering pump by reversing the removal steps, ensuring all connections are secure and free of leaks.

Locate the drive belt tensioner and release tension using a socket wrench.
Remove the old drive belt from the power steering pump and other pulleys.
Install the new drive belt, ensuring it is properly routed according to the vehicle's belt diagram.
Reapply tension using the tensioner.

5. Bleed the Power Steering System
