Audi VW Radiator Coolant Hose Adapter - Genuine Audi VW 5Q0122291E

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 Audi

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

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