On a 2002 Chevrolet Monte Carlo SS with the 3.8L engine, the power steering pump is located on the front of the engine, driven by a belt. It's typically positioned
at the bottom of the engine, near the crankshaft pulley. You'll likely see a relatively large pulley connected to the pump itself. It's usually close to other belt-driven components like the alternator and AC compressor.
To be absolutely certain, you should consult a repair manual specific to your vehicle year and engine. A diagram will be very helpful in locating it.
