I just changed a water pump on a 1994 Pontiac Grand AM SE, 3.1 liter engine w/ac. It was easy. The water pump is located on the passenger side, front part of the engine. Look for the serpentine belt. The top forward shiny wheel is probably it. The belt for this model has three ways to install but for any one model it only works one way. So remember (take a cell phone pic) what way the belt runs.
The belt runs under the water pump, over power steering, then toward the top and back is the alternator. The belt then runs down and forward again to the tension pulley then down and back to the engine pulley. Finally, the belt runs down and forward to under and forward around the a/c then back up under the water pump.
I didn't have a tool to reach the tension pulley so I just slid the belt off the alternate, power steering and water pump and moved it aside. The water pump has a faceplate held on by four 10 mm bolts. USE METRIC!!! You will have to find a way to lock the pulley as it will spin when you try to loosen (or tighten) the bolts. I found a large wrench and placed it between some of the bolts and the pulley shaft and held that while using a socket to remove the bolts.
Ok, the faceplate is off. There should be five bolts holding the water pump on to the engine. I think these were 10 mm too but I don't remember. Compare the holes of the new water pump with the old. Rotate the gasket until all the holes line up. It will only fit perfectly one way.
Put the new one in, secure the bolts. Replace the faceplate. Then, carefully put the serpentine belt back on. Make sure it fits the groves on ALL of the pulleys. Save the alternator for last. At that point you will need to muscle the belt due to the tension pulley. I used a handle of a pair of large pilers to leverage the belt back onto the alternator. It took some work. All told about 90 minutes including a rain delay.
