Installing the coolant pump

The coolant pump must be mounted in the coolant circuit on the pressure side of the heater/heat exchanger inlet (see ).

Ensure the correct direction of flow of the coolant pump to the vehicle coolant circuit.

The installation position of the coolant pump must be selected such that the coolant pump can perform automatic bleeding. The air volume contained in the coolant pump must be able to escape upwards independently via the connection pieces. Incorrect installation may lead to malfunctions of the coolant pump operation.
