BMW HVAC Heater Hose - Genuine BMW 64213400417

Product Information

Your vehicle heater hoses circulate hot engine coolant from the cooling system on the engine through the vehicle heater core, which is located inside the car's dashboard. This coupled with a blower motor, allows for the air inside the cabin to be heated. While critical to the functionality of your climate control system, your heater hoses are also very important to your vehicle's cooling system. Proper maintenance and inspection of your engine's heater hoses will help sustain performance in your climate controls inside the cabin and engine reliability preventing overheating.

• Cracks: Visible cracks on the hose surface, often caused by age or exposure to extreme temperatures
• Leaks at connections: Leakage where the hose connects to other components due to worn or damaged clamps
• Softness or deterioration: The rubber material of the hose becomes soft and loses structural integrity over time
• Low coolant level: Regularly checking the coolant level can indicate a leak
• Coolant smell under the hood or in the cabin: A strong coolant odor when the hood is open or inside the vehicle after the heat has been running
• No heat from the heater: If the heater core isn't receiving enough heated coolant, no heat will be produced within the vehicle Visible coolant leaks: Leakage in the engine bay near the heater hose connections to the firewall

About Genuine BMW

No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.
