CRP Automotive introduces two upgraded Rein Coolant Hose Metal Connectors (CRP Part Nos. CHU0940 & CHK0940) designed for BMW B58 6-Cyl. 3.0L engines. The CHU0940 includes a high-strength aluminum connector and gasket, while the CHK0940 adds a built-in temperature sensor for easy installation. The CRP Automotive Innovation Council identified the OE plastic connector as a common failure point, often cracking due to repeated thermal cycling and hydrolysis. Hydrolysis, the process of water breaking down plastic or rubber, weakens the material over time, leading to failure. Rein’s upgraded aluminum connectors eliminate these issues, providing enhanced durability and reliability.

The Coolant Outlet Connector connects the engine block coolant outlet to the upper radiator hose.

Due to fragile plastic construction and consistent exposure to hot, chemical-rich engine coolant, this piece is prone to degradation and (potentially) complete failure.

Whether you're fixing a failed connector or preemptively replacing this failure-prone component, choose this quality replacement from Bremmen Parts for a lasting repair.
