The invention relates to an oil pump arrangement (1) for a motor vehicle, comprising an oil pump (2) having a pump part (3) and an electric pump motor (4), wherein the pump part (3) is in operative connection with the pump motor (4), the pump part (3) and/or the pump motor (4) being mountable to a housing (5), the housing (5) partially delimiting an oil chamber (7). Tightness problems on the pump part (3) are prevented and the required installation space is low because the pump part (3) can be mounted within the housing (5) and the pump motor (4) can be mounted from the outside to the housing (5).
