1. A traction battery thermal management system comprising:
a battery module having a plurality of battery cells and a heat exchanger for regulating temperature of the plurality of battery cells; a battery housing containing the battery module; a plurality of heat exchanger ports in fluid communication with the heat exchanger for conducting a heat exchange fluid to the heat exchanger; a manifold having a plurality of connector ports corresponding to the plurality of heat exchanger ports for distributing the fluid to the heat exchanger ports; a retention clip connected to one of the battery housing or the manifold; and a receiving portion formed in the other of the battery housing or the manifold to mate with the retention clip, wherein when the connector ports are fully secured to the heat exchanger ports, the retention clip mates with the receiving portion and prevents movement of the manifold to ensure the connector ports remain fluidly sealed to the heat exchanger ports.
