2008 Cadillac DTS Power Steering Reservoir

Hoses touching the frame, body, or engine may cause system noise. So you should verify that the hoses do not touch any other part of the vehicle. Loose connections may not leak but could allow air into the steering system. So you also need to verify that all hose connections are tight.

You may need to check the TORX(R) head bolts on the hydraulic pump housing for tightness, and tighten the bolts to 20-25 N.m (15-18 lb-ft), then check the valve bore plug and the O-ring union fitting and tighten the plug to 50-60 N.m (37-44 lb-ft), lubricate the new O-ring seal with power steering fluid, connect the O-ring seal to the reservoir and connect the reservoir assembly to the hydraulic pump housing, and tap retaining clips with a hammer, attach the pump to the mounting bracket assembly and tighten the mounting bracket bolts to 28-38 N.m (21-28 lb-ft).

You will need to use a clean, new power steering fluid type only.

You will need to remove the mounting bracket bolts from the mounting bracket assembly, remove the mounting bracket assembly from the pump, remove retaining clips from the reservoir assembly using J-42649, remove the reservoir from the hydraulic pump housing, remove the O-ring seal from the reservoir, then discard the O-ring seal.

With hydro-boost only, the oil level will appear falsely high if the hydro-boost accumulator is not fully charged. Do not apply the brake pedal with the engine OFF. This will discharge the hydro-boost accumulator.
