079121147C Volkswagen UNION

This little piece connects the various hoses that carry coolant throughout the engine. Coolant, as you probably know, is what prevents overheating. The Union essentially joins sections of hose together, letting that coolant flow freely. It's a simple part, but it's gotta be solid. Think of your cooling system like a circulatory system, and the hoses are the veins and arteries. The Union is where two of those "arteries" connect. It’s usually found where hoses meet the engine itself, or sometimes joining sections of hose in a tight spot. It keeps everything sealed up so you don’t have leaks. Honestly, without a good Union, you're going to have coolant leaking. That can lead to overheating, and overheating can cause some serious engine damage – blown head gaskets, warped cylinder heads, the whole nine yards. You’ll notice if it's failing – you’ll likely see a puddle of green or orange fluid under your car, or your temperature gauge might start running higher than usual. They’re often made of rubber or plastic, and over time those materials can crack or become brittle. We carry a good selection of Unions, and you can often find what you need quickly at Fixparts Online if you want to take a look. It’s one of those parts where preventative maintenance is a really good idea. Replacing it before it fails can save you a lot of headaches and money down the road. Year-round reliability: Union (MPN 079121147C) includes a 12-month warranty!
