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 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:

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 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.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. 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 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 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

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: 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. 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

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 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. 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.
