VW Radiator Coolant Hose Adapter - Genuine VW 3QF122291

Product Information

A radiator coolant hose adapter is a connector used to join different sections of coolant hoses or to transition between varying hose sizes in a vehicle’s cooling system. It ensures a secure, leak-free connection and helps maintain proper coolant flow between the radiator, engine, and other cooling components. Made from durable materials such as aluminum, plastic, or brass, the adapter withstands heat, pressure, and chemical exposure for reliable long-term use.

• Coolant leaks around the adapter or hose connections.
• Engine overheating, due to restricted or lost coolant flow.
• Cracks, corrosion, or warping of the adapter, weakening its sealing ability.

About Genuine VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

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

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly 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.
