BMW Heater Core - Mahle Behr 64116906270

Product Information

The HVAC heater core is a small radiator-like component located within the vehicle's HVAC (Heating, Ventilation, and Air Conditioning) system. It transfers heat from the engine coolant into the cabin, warming the air that passes through the HVAC system and providing heat to the vehicle’s interior. As hot coolant flows through the heater core, the blower motor pushes air over it, and the heated air is then directed into the cabin.

• Weak or No Heat in the Cabin: If the heater core is partially or fully clogged, the warm air may not reach the cabin effectively, resulting in weak or no heat even when the heater is turned on high
• Sweet or Musty Smell in the Cabin: The heater core contains engine coolant, which has a distinctive sweet smell. If there’s a leak, you may notice this odor inside the car. Over time, this smell can become musty as the leaking coolant sits in the ventilation system
• Fogged-Up Windows: A leaking heater core can allow coolant to enter the HVAC system, which then evaporates onto the windshield, causing a foggy or hazy layer on the inside of the windows. This fog is often sticky and hard to wipe away.

About Mahle Behr

Mahle Behr GmbH & Co. KG is a German corporation active in the automobile industry, headquartered in Stuttgart-Feuerbach. It is a specialist for automotive air conditioning and engine cooling systems. Mahle began in 1920 when pistons made of heavy gray cast iron were being used in internal combustion engines for automobiles and there was a need for a new design. The Mahle brothers countered this trend by producing light-alloy pistons at their small, newly established company however the technology was still finicky and problems come up frequently. They soon determined that they needed to come up with a solution to keep dirt and dust out of the engine so they eventually developed air and oil filters as well. Their perseverance paid off and the light-alloy pistons began to take over the market. Today, half of all automobiles produced worldwide contain MAHLE components. MAHLE offers an extensive range of parts for everyone including pistons, cylinder liners, piston ring sets, bearings, assemblies, valves, valve train components, and air, oil, fuel, and cabin air filters. Their catalog and online database of aftermarket engine components is an indispensable reference.In early 2016, Stuttgart-based MAHLE GmbH increased its holding in the Behr Group from 36.85 percent to approximately 51 percent with the acquisition of all shares in the BWK GmbH holding company. The company now goes by Mahle-Behr.
