What kind of coolant does VW use?

During long winters we spend endless nights shivering under piles of blankets just wishing for the summer heat, but this year we have gotten more than we bargained for with consecutive 90+ degree days. While we’re trying to hang in there, your car is likely suffering just as much. Engines get perfectly hot all on their own, thank you very much, and they don’t need this extra hot weather making things worse. If your car is starting to run a little funny, or worse, actually overheating and failing to start, you may be wondering whether you should get a coolant flush and what kind of coolant VW uses. We’ve got some tips to help keep your vehicle going during this hot, hot summer.

Which coolant should I be using in my Volkswagen?

When it comes to vehicle maintenance, fluid changes top our list of things you should pay attention to and keep on top of. This isn’t to say other things aren’t important, but your engine is basically the heart of your vehicle, and many people are going to find themselves switching cars rather than getting a replacement engine. You likely know how often you should change your oil, since basically every oil commercial will tell you, but how often should you get your coolant checked and flushed?

Volkswagen recommends you flush your engine every four years or 40,000 miles. What Happens When You Use Wrong Coolant VWCoolant, also known as antifreeze, serves a few purposes in your engine. First, it keeps things from getting too hot, but also from any water from freezing. Second? It helps prevent rust and corrosion in your engine, but is less effective at doing this as it gets old and breaks down.

So what kind of antifreeze do you use in your VW? It is highly recommended that you don’t use any kind other than the specific Audi/VW G13 or G12 approved antifreeze. Regular, store-bought antifreeze often has chemicals in it that can wear down gaskets and other parts in your system. At the very least, the antifreeze won’t be as effective to your system, which means you’ll have to change it more often.

Which type of antifreeze your particular model uses should be listed on the expansion tank (G13 or G12) and in your owner’s manual. Also note the color, which will be either pink or purple. Always use the same antifreeze when topping off, or flush your coolant system completely before switching.
