Types of Prius Water Pumps

The Toyota Prius is a mid-sized sedan that is available as a hybrid or standard vehicle. The water pumps, which move coolant from the radiator to the engine, come in a variety of designs from different manufacturers. The type of water pump is directly dependent upon the year and model of the Prius, and whether or not it is a hybrid.

A1 Cardone

The A1 Cardone model is compatible with all Prius models from 2001-2009. The hub and the housing directly beneath the hub are circular. The housing expands into a triangular shape on one side. The A1 Cardone also comes without the extended triangular base for a circular housing unit.
