![]() If it is not the correct coolant according to the manual, we would not advise using it at all. If you don’t have spare G12 coolant to add, then flush the coolant tank out and use the spare coolant you may have laying around. You can’t mix G12 coolant with any other engine coolant. Most Volkswagen and Audi engines use G12 coolant. When it comes to mixing engine coolant, you need to be careful. That’s why we advise looking at the manual and/or engine coolant tank. However, it’s not always a one-size-fits-all when it comes to engine coolant. Early Volkswagen’s and Audi’s from the model years 1980 – 1997 use G11 Coolant, 1998 – 2008 use G12+, and 2008-present use G12++ Coolant & G13 Coolant. If you can’t find it in the manual, it also should be marked on the coolant tank itself. What Coolant Should Be Use in Volkswagen’s or Audi’s?Īgain, a good rule of thumb, look in the owner’s manual. For the best protection and performance, we highly suggest flushing and replacing the coolant in your Volkswagen or Audi every 40,000-50,000 miles or every 3-4 years, whichever comes first. This type of dirty and weak coolant running through the engine will put the engine at risk of overheating, which will dampen the longevity of the engine. The longer engine coolant runs in an engine, it begins to break down, becomes weak, and also becomes dirty. Typically, engine coolant should be changed every 3-4 years. When Should Engine Coolant Be Changed?Ī good rule of thumb when it comes to changing engine coolant is to refer to the owner’s manual. This coolant has a service life of 5 years. G13 coolant is a hybrid that is made up of an optimal ratio of silicate and organic components. ![]() There are 3 different G12 coolants: G12, G12+ (Red), and G12++ (Purple). G12 coolant has a service life of 4-5 years. It is used in high-performance engines with operating temperatures of 90-110 degrees. G12 coolant is red or pink and is made up of carboxylate and ethylene glycol. This coolant has a service life of 3 years. G11 coolant is mainly used in vehicles manufactured before 1996, however, some vehicles up to 2016 could use G11 coolant because of its low heat transfer quality. So what are the differences between the three? G11 is blue or green and is made up of a silicate base that contains inorganic additives. There are three different types of antifreeze: G11, G12, and G13. What is in Engine Coolant?Įngine coolant is made up of propylene glycol, or ethylene glycol, and its own additives. In this post, we’ll be going over what is included in coolant, when coolant should be changed, and what type of coolant should be used in Audi’s and Volkswagen’s. Engine coolant is a fluid that is mixed with water to ensure the radiator doesn’t freeze in extreme cold or overheat in extreme heat.
