Abstract: A motor vehicle cooling system with an electric coolant pump includes a housing with a pump shaft. The electric coolant pump includes an electric motor in a motor housing. The electric coolant pump is at least partially accommodated in the pump shaft. A clamping device including at least two clamping arms is attached to an upper side of the motor housing. The clamping arms are supported with free ends thereof on an inner side of the pump shaft to clamp the electric coolant pump to the housing.

Abstract: A motor housing cover assembly includes a motor housing cover of an electric motor with an upper side and a lower side and a printed circuit board with electronic components. The motor housing cover is penetrated by electrical contacts which each make electrical contact with the printed circuit board with a first end region and are in an electrical plug connector with a second end region, which is arranged on the upper side of the motor housing cover. The motor housing cover, the printed circuit board and the plug connector are at least partially surrounded by a molding compound in a molding process, the molding compound fixing the printed circuit board and the plug connector to the motor housing cover.

Abstract: The invention relates to an electric coolant pump comprising a pump housing, a rotating conveying element for accelerating the coolant, a pump shaft passing through the pump housing and on which the conveying element is mounted, an electric motor for driving the pump shaft; and a control circuit. The conveying element is arranged in a pump chamber formed by the pump housing and a spiral lid. The electric motor is arranged in a motor chamber formed by the pump housing and motor lid. Furthermore, a control circuit chamber is formed in the pump housing, for the control circuit. The control circuit chamber has an opening through which the control circuit can be inserted into the control circuit chamber.
