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 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. 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. It performs best at high temperatures and prevents the engine from being destroyed by heat caused by combustion and friction.

Next to protection against freezing, the G13 is also excellent for cooling and protection against corrosion and chalk deposits. 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 fluidBoth 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

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 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. Therefore, it is important to use the recommended coolant for your specific vehicle and to never mix different types of coolant. The original G12EVO Ready Mix coolant additive is specially designed for the engines of the VW Group’s brands.The new G12evo Ready Mix product is more environmentally friendly and replaces the G13 predecessor, G12 Plus Plus. 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.
