Volvo Heater Hose Junction - Genuine Volvo 3522035

Product Information

The HVAC heater control valve regulates the flow of hot coolant from the engine to the heater core, allowing the system to produce warm air for the cabin. The valve opens and closes based on the driver's temperature settings, controlling how much heat is transferred to the cabin.

• Inconsistent Cabin Temperature: If the valve is stuck open or closed, you may experience fluctuating temperatures inside the vehicle, with heat not matching the temperature settings
• No Heat: A malfunctioning heater control valve can prevent hot coolant from entering the heater core, resulting in cold air blowing from the vents, regardless of the temperature setting
• Coolant Leaks: If the valve is damaged or has a poor seal, it may leak coolant onto the floor of the vehicle or around the engine compartment

About Genuine Volvo

The original parts used by Volvo to build your car are available as replacement parts under the “Genuine Volvo” brand. Manufactured under the direction of Volvo, expect excellent quality and a premium price since these parts are exclusively available through the Volvo Dealership network.

You may not realize this, but the parts that make up your Volvo are not necessarily manufactured by Volvo. No cause for concern, as Volvo designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Volvo 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 Volvo parts box and find an OEM branded part inside, simply with the addition of a Volvo logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
