Since you cannot physically inspect the impeller and inside of a water pump without removing the pump, the best way to know if it is functioning properly is to visually inspect the coolant condition, test the coolant pH and protection levels, test drive the vehicle to verify normal operating temperature, and squeeze ...
A water pump replacement costs between $400 and $800 depending on the vehicle and the difficulty involved. Parts can run from $200 to $400, with labor services similarly priced. These estimates do not include taxes or shop materials, and disposal fees.

Leaking or residue from the front of the engine, overheating, and whining or squealing noises from the engine can indicate a bad water pump.
