Where is the water pump on a 2006 Chevy Impala?

The water pump on a 2006 Chevy Impala is located at the front of the engine, driven by the serpentine belt. It's generally positioned fairly low on the engine block, near the bottom of the timing chain cover (if it has a timing chain) or the timing belt cover (if it has a timing belt).

To be precise, you'll need to access the front of the engine and look for a pump with several hoses attached, typically two large ones. However, without visual inspection, pinpointing its exact location is difficult. A repair manual specific to your 2006 Chevy Impala (3.5L or 3.9L engine) will give you precise diagrams and locations.
