  Q: How to Service and Repair the Power Steering Reservoir on GMC Yukon XL 1500?

  A:

  As a first step for servicing or repairing the Power Steering Reservoir people must drain the power steering fluid from the Power Steering Pump. You should remove pump mounting studs while also taking out the connector and the fitting assembly. Begin service by removing the variable assist steering actuator with its retaining ring followed by taking out the o-ring seal from both the connector and fitting assembly. The service professional must first remove the control valve assembly together with the flow control spring from the pump housing assembly for any replacement work. You should separate the reservoir assembly from the pump housing assembly to remove o-ring seals together with the magnet while performing cleaning operations. O-ring inspection of the Power Steering Pump housing requires leaving the welch plug intact; damage or dislocation of this component warrants a new housing replacement. When assembling the system use fresh o-ring seals while lubricating them with power steering fluid. The pump housing assembly receives the control valve assembly along with the flow control spring and o-ring seals and the magnet as next steps. The reservoir assembly must be connected to pump housing assembly while installing an o-ring seal. Connect the fitting assembly to the steering actuator and variable assist steering actuator following its installation with the retaining ring. End with the step that involves installing pump mounting studs on the pump housing by following up with torque tightening to 58 nm (43 ft. Lbs.) for both the pump housing and connector and fitting assembly to 75 nm (55 ft. Lbs.).
