Where is water pump on 1985 Chevy Caprice?

The water pump on a 1985 Chevy Caprice is located at the front of the engine, driven by the timing belt (or timing chain, depending on the engine). It's generally on the lower part of the engine block, right next to the cylinder head.

To be more precise, you'll need to know which engine is in your Caprice (a 5.0L or 5.7L V8 were common). Even with that information, access can vary slightly depending on accessories mounted around the engine. A repair manual specific to your year and engine will give you the best visual confirmation.
