03L121114B Audi Adapter

This adapter basically connects your thermostat housing to the engine block. It's a bridge, really. It ensures a tight seal between those two parts and directs the coolant flow properly. Sometimes it includes a temperature sensor bung, so your temperature sensor can read accurately. It’s pretty simple in design, but crucial for keeping everything sealed up. Think of it as part of your engine’s cooling system circulatory system. Coolant flows from the engine, through the radiator to cool down, then back to the engine. The adapter is where a key part of that loop connects to the engine itself. It makes sure coolant doesn’t leak out, and that the flow isn’t restricted. If this adapter fails, you’ll likely get a coolant leak, and that’s never good. Coolant leaking can quickly overheat your engine, causing serious damage. You’ll notice if it’s leaking – usually a puddle under your car, or you might smell coolant, which is kinda sweet. Even a small leak can lead to bigger problems, so it’s important to address it when you see it. You can find these pretty easily – we keep a good stock at Fixparts Online, along with all the gaskets you’ll need for the installation. It acts like a shield, keeping your coolant where it needs to be and protecting your engine from overheating. Shop with confidence: Adapter (MPN 03L121114B) comes with a 12-month warranty!
