Audi VW Engine Coolant Outlet Gasket - Genuine Audi VW 04L121688

Product Information

An engine coolant flange is a connector or junction point in the cooling system, typically made of metal or reinforced plastic, that attaches hoses or pipes to the engine block or cylinder head. It serves as a pathway for coolant, directing it through various parts of the engine to maintain optimal operating temperature. The flange is usually equipped with gaskets or O-rings to create a tight seal and prevent coolant leaks.

• Coolant Leaks: A worn or cracked coolant flange can lead to visible coolant leaks around the flange area or under the vehicle, especially near the engine. This is often accompanied by a puddle of coolant or dried coolant residue on the flange or hoses
• Overheating Engine: If the coolant flange is damaged and coolant leaks, the coolant level may drop, reducing its ability to cool the engine effectively. This can lead to frequent or sudden overheating, especially on long drives or in hot conditions
• Low Coolant Warning Light: A faulty coolant flange may cause a slow leak, eventually triggering the low coolant warning light on the dashboard, indicating a need for a coolant check or refill

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.
