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

Product Information

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 corrosion inhibitors make up the bulk of the various chemicals within the coolant. The four main types all use different compositions, giving them different properties suited to different cooling systems.

Switching from G40 to G13 coolant involves more than simply adding the new coolant to your vehicle’s cooling system. It is important to follow the proper procedures to ensure that the new coolant is compatible with your engine and that all of the old coolant is removed. The boiling point of G13 coolant is 175°C (347°F), while that of G40 coolant is 170°C (338°F). The boiling point indicates the temperature at which the coolant boils, which can cause the engine to overheat if the boiling point is too low. Manufacturer Recommendation 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 Therefore, it is important to use the recommended coolant for your specific vehicle and to never mix different types of coolant.BMW, Mercedes, and Volvo had been using IAT coolant since the ’80s. Now the formulation changed to a HOAT fluid. Not much has changed in the composition or the specification since. The intervals that they need to be replaced at have, however, been extended all the way from 2 years in the ’80s initially to 3 years to 4 years in the ’90s to now “LIFETIME” in virtually all BMW applications. Guess what is the weak spot of a modern BMW… The cooling system! We wonder why? Both G13 and G40 coolants provide optimal protection for aluminum and magnesium alloys. G13 coolant provides better protection against corrosion than G40 coolant and is specifically designed to protect engine parts from corrosion. Lubrication 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. On the other hand, G13 is not the best choice for older cooling systems with copper/brass radiators and heater cores. It doesn’t work well with the lead solder. Use antifreeze with G11 or G12 specification instead. 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.

Both G13 and G40 coolants provide optimal lubrication for water pump bearings and other engine components. Lubrication is essential for the proper functioning of engine components and helps reduce wear and tear. Color 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. 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. 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 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.

Engine Coolant Compatability

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. 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. G13 coolant is a long-life coolant that contains organic acids, which help to prevent corrosion and scale buildup in the cooling system. Step-3: Filling the system with the new coolant As critical as those different formulas are, they aren't regularly referred to by them. Instead, the largely accepted naming scheme comes from BASF. As one of the largest chemical producers in the world, BASF's Glysantin line of engine coolants is largely used as a general differentiator between coolant types. Their naming scheme is the originator of the G05, G40, and G48 designation, among others. Below, you'll find those Glysantin product names attached to each respective manufacturer's coolant specifications for ease of understanding. Engine Coolant Types 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)

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:One of the key features of G40 coolant is that it is free of silicates. Silicates are chemicals that are commonly found in other types of engine coolant, but can potentially cause corrosion or other issues in certain types of engines. The new G12evo Ready Mix product is more environmentally friendly and replaces the G13 predecessor, G12 Plus Plus. It is estimated that the manufacturing of G13 produces 11 % lower CO2 emissions than antifreeze with glycol.
