An engine coolant concentrate (antifreeze) based on monoethylene glycol and organic additive technology is called Coolant Concentrate G12, G12+. Has none of the following mineral additives: nitrites, amines, phosphates, borates, silicates, or any other.
- A longer lifespan and less frequent maintenance are possible since corrosion inhibitors have a very low rate of depletion.
- Heat transfer properties that enable boiling-free engine cooling.
- Removal of deposits issues brought by by using hard water.
- Removal of abrasive solids, which improves the protection of the water pump’s joints.
- All metals and alloys utilized in the cooling system of current cars, especially aluminum, have better anticorrosion protection.
- Frost protection, depending on the concentration selected.
- Fantastic antifoaming properties.
- Most international and European standards are met.

What kind of cooling fluid does Audi use?
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.
G11
A traditional silicate foundation plus inorganic additions is used to create G11 coolant. This coolant is utilized in automobiles built prior to 1996. Even yet, certain vehicles with model years as recent as 2016 can survive the usage of G11.
G11 coolant is renowned for preventing corrosion and providing surface protection. Green or blue antifreeze is this substance. G11 has a three-year maximum shelf life, but as soon as it is utilized, its protective qualities start to deteriorate. Additionally, because this coolant cannot withstand temperatures exceeding 105 degrees Fahrenheit, heat transfer is reduced.
A car with an aluminum radiator or block is not a good candidate for G11 due to the lack of protection. Additionally, you should refrain from utilizing budget brands like Polarnik or Euroline. These companies have a history of mislabeling the degree of protection provided.
G12
G12 coolant comes in a variety of forms, however the bulk of them are pink or red in color. These formulations are based on ethylene glycol and carboxylate chemicals and don’t contain silicates. The current formulation, however, means that the anti-corrosion characteristics are merely selective, acting only where corrosion is already taking place.
You will need to combine and dilute G12 with the right amount of distilled water since it is typically sold as a concentrate. This ratio is stated on the label.
There is G12 + antifreeze as well, but nothing differs significantly. Despite being red, this coolant is said to be beneficial for the environment. There is also G12 ++, and its goal is to be more durable. An enhanced combination of carboxylated chemicals is provided by this formulation.
Is it possible to add coolant to my Audi?
Use ONLY the certified Audi coolant antifreeze standards G13, G12++, G12+, or G11 for VW. Use of common store-bought coolant is NOT recommended since it frequently does not meet the requirements of an Audi cooling system. The majority of Audi coolant antifreeze is concentrated.
Can I substitute G12 for G13?
On the other hand, G13 is not the greatest option for older cooling systems with copper/brass radiators and heater cores. Silicate additives for use in radiators with aluminum. Lead solder doesn’t function well with it. Instead, use antifreeze that meets G11 or G12 specifications.
What shade is the antifreeze in 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.
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.
How do I refill the coolant in my Audi?
On the coolant expansion tank, check the coolant level. Fig. 1. The coolant level should fall between the markers when the engine is cold. It can be just a little bit above the top mark when the engine is heated.
Electric hybrid drive There are two distinct coolant expansion tanks in your Audi A3. Link must not open the smallest of the two expansion tanks.
With the expansion tank cap covered with a cloth, carefully unscrew the cap in the opposite direction. WARNING!.
Can I add water to top off the coolant?
Only in an emergency situation when the coolant liquid level is lower than it should be, should coolant be topped off with water.
You shouldn’t rely on topping up with water to bring you safely to the closest garage and help you find any problems.
A small amount of water added to coolant shouldn’t cause any significant harm, but too much water will lower the coolant’s boiling point and prevent it from performing as effectively.
What occurs if the wrong coolant is placed in the car?
The performance of the car can be hampered if the wrong coolant is used or if several types are mixed together. Additionally, the radiator’s corrosion may worsen. It’s crucial to remember that color alone cannot accurately identify the type of coolant you should use. The radiator, water pump, radiator hoses, cylinder gasket, and other components can suffer corrosion and other issues as a result of using the incorrect coolant. Having a qualified auto mechanic handle your vehicle’s maintenance is the greatest method to guarantee that you obtain the right coolant.
