It performs best at high temperatures and prevents the engine from being destroyed by heat caused by combustion and friction. It is environmentally friendly, as it contains no nitrates, phosphates and other harmful agents, and is produced from renewable resource. When mixed in the recommended ratio with distilled or demineralized water, its chemical inhibitors protect engine coolant passages, radiator, water pump, and cooling system pipes from corrosion damage. When it comes to ease of use, VW Volkswagen Original G13 Coolant is pre-mixed and ready to pour, eliminating the need for dilution. Its main purpose, in summer, is to maintain the engine temperature below 100°C to prevent it from overheating and, in winter, to serve as antifreeze.

As opposed to many earlier specifications using OAT-technology (Organic Acid Technology), G13 boasts silicate additives for extra healing aluminium protection. The introduction of Silicate additives makes G13 ideal for prolonged use in all modern radiators, especially those derived from aluminium, cast iron, and magnesium alloys. Bearing similar exceptional cooling and antifreeze performances as G12++, the G13 boasts a vivid purple/violet colour.

However, we recommend thoroughly flushing your cooling system when upgrading from a different type of coolant. Glad I drained the whole thing, can I please get a confirmation G12 is the correct coolant to refill the empty system with? I know that Audi's factory fill coolant is supposedly lifetime, but I need to top off my coolant tank and my manual states that it was factory filled with G13. I mentioned this to a Halfords staff member whose knowledge was questionable and didn't convince me.

You will discover the significant advantages of this latest specification in explicit detail by reading on. Make sure the wires are dirt free and use a non conductive electric contact cleaner on the test probe.Products shown, tagged or featured on YouTube by creators are sold by merchants and are subject to merchant's terms and conditions. I have also seen that G13 should be used, and that there is also this G12 evo but just read another thread on coolant which had an Audi America article stating that it must NOT be used in vehicles other than the A8 and R8 I believe.
