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.

OEM Replacement Lower Radiator Hose for E46 3 series (Non-M3). We recommend replacing the Coolant Temperature Sensor while replacing this hose as the original sensor is often damaged while trying to remove it from the old hose. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
