Where is the water pump on a 1990 Chrysler New Yorker 3.3 L engine?

On a 1990 Chrysler New Yorker with the 3.3L engine, the water pump is located on the front of the engine, at the bottom, driven by the serpentine belt. It's generally fairly low and close to the crankshaft pulley. You'll need to look from the front of the car, potentially after removing some under-hood components for a better view.
