Show original supplier description
The Rein Automotive Coolant Outlet Connector offers a significant upgrade over the factory plastic component. Constructed from aluminum, it provides enhanced durability and resilience, addressing the common failure point of the original plastic part. This connector is crucial for draining hot coolant from the engine block to the upper radiator hose. This metal B58 coolant connector is manufactured by Rein Automotive, a supplier of original equipment and replacement parts that meet or exceed BMW's design, fitment, and performance requirements. Rein parts undergo testing with ISO and German TUV for quality control, presenting a cost-effective alternative to expensive Original BMW parts. Installation Note: The coolant temperature sensor is sold separately. Please refer to the fitment list for exact compatibility.
