G12 is a pink or red coolant based on ethylene glycol and carboxylate. It contains no silicates and has a lifespan of four to five years. G12 coolant is used in the 1996 through 2001 model years. 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 indeed a VW/Audi specific coolant and is pink/red in the jug. The coolant is a concentrate and must be mixed with 50% distilled water before filling the cooling system.
G12 coolant is red or pink and consists of carboxylate and ethylene glycol. It is used in high-performance engines with operating temperatures of 90-110 degrees. G12 coolant has a service life of 4-5 years.
The G13 has the same exceptional cooling and antifreeze performance as the G12++ but is made using glycerin. Glycerin is much less polluting than glycol. The G13 is also great for cooling and protecting against corrosion and limescale.
If it’s just a small amount, just use tap water, but if you have to do it regularly because there’s a leak, alternate filling with decent antifreeze, then water, etc. to keep it concentration. I would top it off with some G12++ coolant mixed 50:50 with water.
The only types of coolant you should put in your Volkswagen are either G11 or G12 approved anti-phosphate, anti-amine, anti-phosphorus coolants – depending on what the owner’s manual specifies . Also look for the recombined coolant type on your expansion tank.
G12 is a pink or red coolant based on ethylene glycol and carboxylate. It contains no silicates and has a lifespan of four to five years. G12 coolant is used in model years 1996 through 2001.
G12++ mixes well with G13, also with G11, G12 and G12+, but there is a loss of corrosion protection.
Can you top up your coolant with water? Coolant should only be topped up with water in an emergency when the coolant level is lower than specified. While adding water will help you get to the nearest repair shop safely and identify problems, it should not be relied on.
Blend is OK.
G13 is not ideal for older cooling systems with copper/brass radiators and heater cores (it doesn’t integrate well with the lead solder). Antifreeze with G11 or G12 specification should be used instead.
Phosphated HOAT (P-HOAT)
This coolant is available in pink or blue color. Phosphated HOAT uses phosphates along with organic acids to prevent corrosion. This coolant is compatible with models from car manufacturers such as Hyundai, KIA and Honda.
Volkswagen uses a special Audi/VW G13 or G12 approved antifreeze. The exact type your particular model uses should be stamped on the reservoir and listed in the owner’s manual. Volkswagen coolant is always pink or violet in colour.
Engine coolant, also known as antifreeze, is mixed with water to prevent the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it’s important to know which type is right for your car or truck.
Using the wrong coolant can lead to corrosion and other damage to the radiator, water pump, radiator hoses, cylinder gasket and more. The best way to ensure you are getting the correct coolant is to have your vehicle serviced by a professional automotive technician.
