The Black Market Parts (by Precision Raceworks) BMW Billet Coolant Flange was designed as a replacement for the factory plastic flange that is found in the hose that connects the thermostat to the cylinder head. The plastic flange commonly cracks, which leads to coolant loss and engine overheating. Replace your coolant flange before disaster occurs and leaves you stuck on the side of the road.

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.
