Abstract
A water pump for an internal combustion engine is provided comprising a pump holder and a pump block. The pump block includes a pump mount having a shaft passing therethrough terminating in an impeller. The pump block is mounted to the holder via a quick release, bayonet type coupling with the pump mounted sealed to the holder. A snap fitting locking ring locks the block to the holder and prevents disconnecting the coupling by blocking reverse rotation of the block relative to said holder.
