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

Product Information

Negative Effects: While technically compatible with the older Yellow coolant, the early formula is very old, and any car using it should be drained, flushed, and replaced with the modern Q1030004 fluid 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 1: Mixing different types of coolant can alter the chemical properties of the coolant, which can result in corrosion, deposits, and other issues that can cause damage to your engine. 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. 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 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 It performs best at high temperatures and prevents the engine from being destroyed by heat caused by combustion and friction.You should also remove the thermostat and flush the system with clean water to remove any remaining traces of the old coolant. Step-2: Choosing the correct coolant 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 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 Following this maintenance schedule will ensure the prolonged life of your cooling system. Below is a radiator with clogged ports due to the build-up of silicate. This can lead to an overheating engine, so consider the perceived cost-benefit you get from skipping coolant flushes versus the cost of a new engine. 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

You can use the previous Q1030004 fluid in a Q1030005 factory-filled system ONLY IF the system is drained, flushed, re-drained, and then filled with Q1030004. The protection is nearly identical; however, the Q1030004 is not designed to last and perform as long as the new Q1030005. 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 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. 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. 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. LubricationG05andG48 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. G13 coolant is recommended by Volkswagen, Audi, and Porsche, while G40 coolant is recommended by Mercedes-Benz and BMW. It is estimated that the manufacturing of G13 produces 11 % lower CO2 emissions than antifreeze with glycol. Genuine G12evo (new version of G13) coolant additives protect individual engine components, safeguarding the engine’s long service life. It contains substances that form a protective coating against corrosion, helping to prevent foaming and neutralise ‘hard’ water ie water with a high mineral content.

G40 coolant is a type of engine coolant that is commonly used in certain European car models, including newer models of Mercedes-Benz and BMW. It is also sometimes referred to as “MB G40” or “BMW G40.” VW GROUP Coolant Anti Freeze G12 evo replaces G12 plus AND G13 This bottle replaces the 1.5 Litre Bottle (G013A8JM1) This fluid is also for: 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 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 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. 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. 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 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?

Technically, you can mix G40 coolant with G13 coolant in an emergency situation. However, it is not recommended to do so for several reasons. 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 Swedes are either hated or loved for their odd choices and unique style. But when it comes to engine coolant, Volvo has remained consistent. Their only coolant formula is that of a G48-type. G48 Coolant 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 RecommendationNext to protection against freezing, the G13 is also excellent for cooling and protection against corrosion and chalk deposits. 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:
