Ethylene glycol and carboxylate are the foundation of G12, a pink or scarlet coolant. It has a service life of four to five years and doesn’t contain silicates. 1996 through 2001 model years using G12 coolant. This coolant has a boiling temperature of 118 C, or 245 F, and a freezing point of -50 C, or -58 F.
G12 coolant has a fifty to sixty percent ethylene glycol content, which enables it to function as effectively as possible. Additionally, it has roughly 5% distilled water in it. There are other ingredients, such as a dye for increased visibility.
G12 coolant has the drawback that it doesn’t stop rusting. It doesn’t begin to combat rust until after the process has begun. However, it is efficient in eliminating corrosion that has already begun to build.

What type of coolant does Audi advise?
Use ONLY Audi VW G11, G12+, G12++, or G13 Audi coolant antifreeze that has received OEM approval. Use of common store-bought coolant is NOT recommended since it frequently does not meet the requirements of an Audi cooling system. The cooling system in an Audi reacts negatively to inferior coolant.
Is the coolant in G12 and G13 the same?
The G13 is made using glycerin yet has the same great cooling and antifreeze capabilities as the G12++. Compared to glycol, glycerin is far less damaging to the environment. The G13 is also very good at cooling and guarding against rust and chalk buildup.
Does Audi employ a unique coolant?
Regardless of whether you drive a BMW, Porsche, Mercedes Benz, Audi, Mini, or Volkswagen, your car circulates a solution of water and coolant to dissipate the heat generated within the engine and prevent it from melting down completely (one notable exception are older Porsche models that are air and oil cooled and did not use water or coolant, but instead circulated a large amount of oil to dissipate the heat).
A Spectrum of Colors
Which coolant type is best for your BMW, Porsche, Mercedes Benz, Audi, or Volkswagen out of the many available options? The answer is the kind that was initially installed in your car. Your coolant may be green, pink, blue, yellow, or even clear depending on the manufacturer. All coolants are naturally transparent, and dye is used to give them color. Each company adds their own color mixture to their coolant; this has no impact on the coolant’s chemical properties. Because the water in Europe is substantially harder than the water in the United States, European manufacturers prefer coolant that is phosphate-free.
Inorganic Acid Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT) are the three most common coolant types available today. A HOAT coolant is used by your BMW, Porsche, Mercedes Benz, Audi, or Volkswagen.
In order to protect aluminum surfaces, silicate is added to OAT coolants to create HOAT coolants. The cylinder heads and radiators, as well as other parts of your BMW, Mercedes Benz, Porsche, Audi, and Volkswagen engine and cooling systems, are constructed of aluminum.
Silicate and phosphate corrosion inhibitors are not used in OAT coolants. These coolants are made to last for 150,000 miles and have a long service life (or 5 years). It should be mentioned, nevertheless, that German Auto Center and the majority of manufacturers advise cleansing or replacing the coolant every two years.
The metal (Iron) components of the engine and cooling system are protected by traditional coolants, which are IAT coolants and use silicate and phosphate corrosion inhibitors. IAT coolants shouldn’t be utilized because the majority of the iron components in your BMW, Mercedes Benz, Porsche, Mini, Audi, and Volkswagen have been replaced with aluminum and other lighter composites.
It’s crucial to keep in mind that modern German performance cars, whether you drive a Porsche, Mercedes Benz, Mini BMW, Volkswagen, or Audi, will last you for many miles and years if you maintain them properly. German Auto Center in Austin is the place to go for German auto repairs. We will be pleased to help you!
What color is the coolant in an Audi?
What color coolant is used in the Audi A4? It’s amazing to realize that color is irrelevant. Hybrid Organic Acid Technology (HOAT) coolants are orange and yellow, unlike the majority of Organic Acid Technology (OAT) coolants, which are typically orange, yellow, red, or purple.
Can G12 and G13 coolant be mixed?
- G11 blends well with G12+, G12++, or G13 but not G12
- G11 does not mix well with G12, however it does with G12+, G12++, and G13.
- G12+ blends nicely with G12++ and G13, as well as G11 and G12, although the corrosion protection is reduced.
- G12++ mixes nicely with G13, as well as G11, G12, and G12+, although the corrosion protection is reduced.
- G13 mixes nicely with G12++, as well as G11, G12, and G12+, however the corrosion protection is reduced.
The best coolant for an Audi A4 is…
Which coolant and antifreeze for the Audi A4 are the most widely used?
- From $15.99 for a gallon, Prestone All Vehicles 50/50 Antifreeze/Coolant.
- From $18.99 for a gallon, Prestone All Vehicles Full Strength Antifreeze/Coolant.
- Gallon of Peak 50/50 Antifreeze/Coolant, from $15.99.
In my Audi, can I use Prestone antifreeze?
For Audi 19972007, Volkswagen 19972008, Porsche 19992009, and Jaguar 1999 and newer, use our specially developed formula. This technology controls the engine’s temperature, keeps it from freezing, and guards against corrosion.
Can I use G12+ for G13?
advantages of adding silicate to radiators made of aluminum G13 doesn’t work well with lead solder, so it’s not recommended for older cooling systems with copper/brass radiators and heater cores. Instead, use antifreeze that meets G11 or G12 specifications.
Possibly mixing G12 and G12+
While it is generally advised to dilute antifreeze with deionized or demineralized water, Coolant Concentrate G12, G12+ is made to be adaptable to various water qualities and is compatible with hard water. Other coolants and Coolant Concentrate G12, G12+ can be safely used together as they are entirely miscible. It is advised to flush and drain cooling systems that include traditional mineral coolants first before recharging with diluted Coolant Concentrate G12, G12+ since Coolant Concentrate G12, G12+ uses an inhibitor type that is considerably different from that used in those classic mineral coolants. Failure to do so could drastically reduce the product’s performance and lifespan.
Can I fill my VW with ordinary coolant?
What sort of antifreeze do you put in your Volkswagen then? It is strongly advised that you only use antifreeze that has been approved by Audi/VW under G13 or G12. Regular store-bought antifreeze frequently contains compounds that can damage gaskets and other system components.
