• Q: How to replace the Power Steering Reservoir on 2009 Cadillac DTS?

  A: The Power Steering Reservoir replacement process begins by unscrewing the mounting bracket bolts from the mounting bracket assembly which then facilitates taking off the mounting bracket assembly from the pump. The reservoir assembly requires removal of retaining clips using J-42649 before detaching from the hydraulic pump housing. Remove the O-ring seal from the reservoir along with discarding it. Use J-42649 to test TORX(R) head bolts on the hydraulic pump housing during assembly. Tighten them to 20-25 Nm (15-18 lb ft). The valve bore plug requires tightening at 50-60 Nm (37-44 lb ft) with an O-ring union fitting and the valve bore plug also needs checking. Install the new O-ring seal on the reservoir by applying power steering fluid and position it correctly so the mounting hole of the reservoir matches the opening on top of the housing assembly for protection. Secure the connection between the reservoir assembly and hydraulic pump housing by making sure the retaining clip reaches its complete seating position. You must use a hammer to tap the retaining clips before attaching the pump to the mounting bracket assembly where you will tighten the mounting bracket bolts to 28-38 Nm (21-28 lb ft).
