Heater Cores, Lines & Valves

How does a BMW heater work? On combustion engine powered BMWs, hot coolant from the engine is routed to a small specialized radiator called a heater core. A BMW's heater core has heater core lines attached at the inlet and outlet, and a heater valve which regulates the coolant flow based on the HVAC climate controls in the car. We stock Genuine BMW, OEM, and aftermarket replacement parts for the heater core, heater lines, and heater valves on most BMWs. Use our SEARCH BY MODEL feature to filter these items for your BMW.
