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

Product Information

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. 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. 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:

Next to protection against freezing, the G13 is also excellent for cooling and protection against corrosion and chalk deposits. 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 CoolantThe new G12evo Ready Mix product is more environmentally friendly and replaces the G13 predecessor, G12 Plus Plus. 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 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.” 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. G13 coolant is recommended by Volkswagen, Audi, and Porsche, while G40 coolant is recommended by Mercedes-Benz and BMW.

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 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. 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.

Technically, you can mix G40 coolant with G13 coolant in an emergency situation. However, it is not recommended to do so for several reasons. 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. 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) Both G13 and G40 coolants have a lifespan of up to five years or 150,000 miles, whichever comes first. However, it is essential to note that factors such as driving conditions, climate, and usage patterns can affect the coolant’s lifespan. Chemicals

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 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. 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. 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.Therefore, it is important to use the recommended coolant for your specific vehicle and to never mix different types of coolant. Here are the steps to follow when switching from G40 to G13 coolant: Step-1: Flushing and draining the cooling 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.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 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 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
