Abstract

A motor vehicle coolant pump for supplying coolant to an engine includes a two-part pump housing comprising a pump rotor housing part and a body housing part. The pump rotor housing part comprises a first mounting flange, and the body housing part comprises a second mounting flange which together fix the housing parts with respect to each other and allow a mounting of the housing parts on each other in every rotary position. A pump rotor is arranged in the pump rotor housing part. An axial coolant inlet and a tangential coolant outlet are provided on the pump rotor housing part. A rotary fixation comprises a recess at the pump rotor housing part and a nose which engages in the recess. The rotary fixation allows the pump rotor housing part and the body housing part to be mounted with respect to each other in only one single rotational angle.
