VW Coolant Outlet Flange - Genuine VW 021121117A

Product Information

An Engine Coolant Outlet Flange is a component of a vehicle's cooling system that connects the engine's coolant passages to the radiator and the rest of the cooling system. It serves as an interface for coolant to exit the engine after it has circulated through the engine block and absorbed heat. The flange typically includes ports for hoses, fittings, or sensors that monitor coolant temperature or flow.

• Coolant Leaks: One of the most common symptoms of a failing coolant outlet flange is visible coolant leaks. These leaks may appear around the flange or hose connections and can lead to a low coolant level in the system, increasing the risk of engine overheating
• Overheating Engine: If the coolant outlet flange is compromised and not allowing proper coolant flow, it can result in insufficient cooling. This can cause the engine to overheat, leading to potential engine damage or failure
• Corrosion or Damage: Inspecting the flange may reveal signs of corrosion, cracks, or physical damage. Corrosion can weaken the flange, leading to leaks, while cracks can allow coolant to escape and disrupt the cooling system

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.
