G40 is a new type of coolant designed to be used in newer cars that require it, but are backwards compatible with other types. It was created by General Motors, and the “G” stands for GM—but it is not the same as G12, the type of coolant that older models of GM vehicles use. They are two different fluids.

What does G40 mean coolant?
It is necessary to dilute GLYSANTIN® G40®, an ethylene glycol-based engine coolant concentrate, with water prior to use. Salts of organic acids and silicates make up the corrosion inhibitor package in GLYSANTIN® G40® (Si-OAT coolant). As far as contaminants go, GLYSANTIN® G40® has none of the above.
What cars use G40 coolant?
Using Zerex G40 Antifreeze/Coolant in cars and light trucks has been proven to extend the life of the engine. BMW, Mercedes-Benz, Porsche, VW, and some older Audi and Volvo models recommend this premium carboxylate formulation.
What type of coolant is G12?
Carbonate and ethylene glycol make up the G12 coolant, which is either red or pink. It is used in engines that operate at temperatures between 90 and 110 degrees Fahrenheit. The lifespan of G12 coolant is 4-5 years.
Can I use G30 coolant instead of G12?
Just like Pentosin’s G12, but manufactured by a different company, G30 is also safe to mix with G12.
What type of coolant does Volkswagen use?
Audi/VW G13 or G12 antifreeze is the antifreeze used by Volkswagen. The expansion tank should be stamped with the model’s specific type, and this information should be included in the owner’s manual as well. The coolant in Volkswagens is always pink or purple. If you’re simply restocking, stick with the color of your vehicle.
Who makes G12 coolant?
AWD Coolant G12++To keep combustion engines’ cooling systems free of corrosion and frost, RAVENOL LTC Lobrid Technology Coolant uses 1.2-Ethanediol (mono ethylene glycol), an environmentally friendly, silicate-free OAT.
Is G40 an OAT?
To prevent rust and corrosion in the cooling system, ZEREX G40 uses the Si-organic acid technology (Si-OAT), which is free of nitrite, amine, and phosphate.
Can you use any coolant in a VW?
What kind of antifreeze do you use in your VW? Any antifreeze other than Audi/VW G13 or G12 approved antifreeze is strongly discouraged. Gaskets and other components in your system can be worn down by chemicals in regular, store-bought antifreeze.
What can I mix with G12 coolant?
A VW/Audi-specific coolant, G12, is indeed pink or red in the bottle. Before filling the cooling system, the coolant must be mixed with 50 percent distilled water to ensure that it is safe.
What coolant is equivalent to G13?
There is no difference in cooling and antifreeze performance between the G13 and the G12++, but the G13 is made with glycerin.
