G12 is usually sold as a concentrate, so you will need to mix and dilute it with the appropriate amount of distilled water. However, the newer formulation means that the anti-corrosion properties are only selective, working where there is already corrosion occurring. These formulations don’t contain silicates, making them based on ethylene glycol and carboxylate compounds. There are various types of G12 coolant, but the majority are colored pink or red. These brands have shown to mislabel the amount of protection offered. You also want to avoid using low-end brands, such as Polarnik or Euroline. G11 isn’t good in a car with an aluminum radiator or block because of the lack of protection. Plus, this coolant doesn’t tolerate higher temperatures above 105 degrees Fahrenheit, making heat transfer lower. However, the shelf life of G11 is only up to three years, and the protective properties begin to degrade as it is used. This antifreeze is green or blue in color. G11 coolant is known for creating protection on the surfaces and slowing down corrosion. However, there are some cars with model years up to 2016 that can tolerate the use of G11. This is the coolant used on vehicles made before 1996. G11 coolant is produced from a classic silicate basis with inorganic additives. RELATED: Can You Use Water Instead of Coolant? (Why You Shouldn’t) G11 vs. Each of these has its own properties and is used for a variety of applications. In general, there are three types of antifreeze formulations: G11, G12 and G13. When the consistency isn’t right or there’s not enough fluid, friction can occur.

Just like motor oil, engine coolant also provides some lubrication to the internal components. It also ensures that the coolant doesn’t freeze during the winter. Engine coolant flows through the cooling system and engine to remove heat from the hot motor. What is Engine Coolant?Įvery type of engine coolant is made from a mixture of ethylene glycol or propylene glycol with a unique blend of additives. However, it is effective at getting rid of corrosion as it starts to form. It only starts to fight against corrosion once the process has started. The downside to G12 coolant is that it doesn’t prevent corrosion. There are other additives included, such as dye for better visibility. It also contains about five percent distilled water. The ethylene glycol percentage of G12 coolant is between fifty and sixty percent, allowing it to perform as well as possible. The freezing point of this coolant is -50° C or -58° F with a boiling point of 118° C or 245° F. G12 coolant is used in model years 1996 to 2001.

It doesn’t contain silicates, and has a service life lasting from four to five years. G12 is a pink or red coolant based on ethylene glycol and carboxylate. How to Choose the Best Coolant What is VW G12 Coolant?
