VW Volkswagen Original G13 Coolant Audi (Succesor Of G12++)

Product Information

Once you have chosen the correct coolant, you can fill the cooling system with the new coolant. You should follow the manufacturer’s instructions for the correct ratio of coolant to water, which is usually 50/50.

G12 Evo is now required in all VW Group vehicles, this is the most up to date, latest version of coolant from VW Group. G12 EVO is the latest correct coolant and replaces G12, G12+ & G13, it may have been made after your car was built (this will be the reason it may not appear in your handbook/manual, or on the coolant cap itself) Therefore, it is important to use the recommended coolant for your specific vehicle and to never mix different types of coolant. G05andG48 are compatible with each other, regardless of color. However, we advise a switch to G48 after performing a full cooling system drain, flush, and re-fill, due to current availability.

Another important aspect of G40 coolant is that it is designed to be long-lasting, with a lifespan of up to five years or 150,000 miles, whichever comes first. This can help minimize the frequency of your car’s maintenance needs and provide peace of mind for drivers. Differences Between G40 and G13 Coolants: Comparison Table Spec/Feature OATs, HOATs, and Si-OATs, am I right? I know that sounds confusing, but you don't need to know the chemical makeup of every fluid in your car; that's an engineer's job. What you do need to know is which coolants can be used together. Carrying around spare fluids is a nice thought, but not everyone has the space for them, so knowing which coolant types that can top off your system in a pinch can save your cooling system. The newer OAT coolants work a bit differently than the older silicate-based IAT coolants. First off, these coolants don't have any silicates or phosphates. They contain organic salts to protect the cooling system. This means that their service life is extended. This category of antifreeze cannot be used in systems containing yellow metals, meaning older cars with copper and brass cooling system components can not use this type of coolant. Newer cars with aluminum engines and cooling system components are mostly OK.

Antifreeze is the hidden hero of our car’s engines. If you don’t know how antifreeze works, it’s pretty simple. Antifreeze is added to the water in your engine’s cooling system that lowers its freezing point (and raises its boiling point too). It’s why the liquid in your radiator doesn’t freeze when everything else seems to be! You can choose a concentrated coolant that needs to be mixed with water or a ready-mixed one that can be used immediately. About our Antifreeze and Engine Coolant It provides optimum anti-freeze, overheating and corrosion protection. Its special composition raises the water’s boiling point to 135C (275F) while preventing evaporation, and lowers the freezing point to -40C (-40F) while maintaining a constant pH value.

Technically, you can mix G40 coolant with G13 coolant in an emergency situation. However, it is not recommended to do so for several reasons. G13 coolant is pink in color, while G40 coolant is yellow. The color of the coolant does not affect its performance but can help identify the type of coolant used in the engine. Freeze Point Reason 2: Mixing different types of coolant can also reduce the effectiveness of the coolant, which can cause your engine to overheat and potentially cause damage. The manufacturer’s recommendation is based on the specific requirements and characteristics of the engine, and using the recommended coolant can help ensure proper engine performance and longevity. How to switch from G40 to G13 coolant? Step By Step

Both G13 and G40 coolants have a freeze point of -37°C (-34°F), making them suitable for use in cold climates. The freezing point indicates the temperature at which the coolant freezes, which can cause engine damage if not suitable for the climate. Boiling Point Negative Effects: Mixing with an older coolant will result in accelerated internal wear on cooling system components. G13 coolant is recommended by Volkswagen, Audi, and Porsche, while G40 coolant is recommended by Mercedes-Benz and BMW. By avoiding silicates, G40 coolant like – Zerex G40 is able to provide better protection and lubrication for your engine over the long term. Due to G12 no longer being made, if the system needs a top-off, it is not recommended to mix antifreeze types. A drain, flush, and re-fill are suggested with the latest fluid. All other coolant forms are still in production and can be found with ease. With that said, updating to the most modern coolant isn't a bad idea. It's the best blend of corrosion-inhibiting organic additives and lubricating silicates.

Coolant as we know it today, also called antifreeze, is a kind of “super water.” Within it are many chemical compounds, the most important being Glycol. When added to water, Glycol raises the boiling point and lowers the freezing point, stabilizing it for use in almost every application while also containing the lubricants that help the water pump and thermostat function effortlessly. The rest of the chemicals are corrosion inhibitors and dyes (orange, green, red, or blue). The corrosion inhibitors are critical to the type of material that the engine is made from and are categorized into four different types. Engine Coolant Corrosion Inhibitors: Volkswagen/Audi Group is a bit of an outlier compared to other manufacturers in that they've consistently updated their cooling systems, engine materials, and engine coolants over the last three decades. That's resulted in five different potential coolants for your car available in three different colors and a few confusing names. Struggle no more when choosing your next coolant, as this section should be all you need. G11 Coolant Electrolysis is a fun by-product of not changing coolant on time, and it has some very negative impacts on all things aluminum. As you can see in the picture below, electrical current traveling through the coolant seeking a path of least resistance, found its way out by creating new passages. Not a good thing long-term for your engine and all-aluminum parts in that system.

G13 contains some silicate additives for that additional healing aluminium protection. This is contrary to some earlier specifications that use OAT-technology (Organic Acid Technology). Silicate additives make G13 ideal for long-term use in all modern radiators, especially those constructed from aluminium, cast iron and magnesium alloys. If you are unsure about which type of coolant to use, it is always best to consult your owner’s manual or a qualified mechanic for advice. By using the correct coolant for your vehicle, you can ensure that your engine is protected and running smoothly.

Once the system is flushed and drained, it’s time to choose the correct coolant. G13 coolant is recommended for most modern Volkswagen and Audi vehicles, but you should always consult your owner’s manual or a qualified mechanic to ensure that the coolant you choose is compatible with your engine. BMW is pretty simple when it comes to its coolants. For what seems like forever, BMW has used either an IAT or HOAT coolant formula for all of their vehicles. Up until recently, a blue G48-spec coolant was the only type required. However, beginning a few years ago, BMW switched to a Si-OAT formula called HT12. For whatever reason, this newest formula doesn't follow BASF's Glysantin specification naming scheme, but that might just make it easier to remember and differentiate from other formulas. G48 Coolant The G13 has a purple/violet colour and has the same exceptional cooling and antifreeze performance as G12++. The main difference: it is manufactured using glycerin instead of glycol. Glycerin is much less harmful to the environment than glycol. One is a bi-product of biodiesel production, the other is produced from mineral oil.
