Where is the power steering pump on a 2005 Monte Carlo??????

based on what kind of a motor you have, it's installed onto the front of the motor where the serpentinve belt can drive it. The 3.1L pump is about in the center of the motor area and the 3.4L is more behind the motor. Some of these had a remote reservoir so as to be able to dump PS liquid into it a little easier. If that is the case, follow the bigger hose down to the pump.

I was a GM mechanic for many years.
