The new G12evo Ready Mix product is more environmentally friendly and replaces the G13 predecessor, G12 Plus Plus. 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 Next to protection against freezing, the G13 is also excellent for cooling and protection against corrosion and chalk deposits.

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. Here are the steps to follow when switching from G40 to G13 coolant: Step-1: Flushing and draining the cooling system 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. ChemicalsSwitching 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. 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.

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. One of the significant differences between G13 and G40 coolants is their vehicle compatibility. G13 coolant is recommended for use in Volkswagen, Audi, and Porsche vehicles, whereas G40 is recommended for use in Mercedes-Benz and BMW vehicles. Lifespan 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

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.

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.”

BMW/MINI Coolant Specifications

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 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: 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. 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. 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
