Power Steering Pump was leaking from the highpressure line ORing. For Preventive Maintenance I decided to change the pump along with the highpressure line. Pump uses an EVO solenoid, a bypass tube is installed in this video. Overall this is a straightforward job if you have the right tools. Hardest parts are removing the fan shroud nut, removing the pulley, and solo realigning the pump. Done on a 1997 GMC Safari RWD.
