Where is the water pump located on 1994 Chevy Silverado?

On a 1994 Chevy Silverado, the water pump is located on the front of the engine, driven by the timing belt. It's usually fairly low down and relatively easy to see once you're looking at the front of the engine. You'll likely see hoses connected to it.

However, the exact location can vary slightly depending on the specific engine (e.g., 4.3L, 5.0L, 5.7L, 6.5L diesel). To be absolutely certain, you'll need to consult a repair manual specific to your truck's engine. A repair manual will have diagrams and precise instructions.
