Because of this, coolant contains inhibitors to help protect engine and cooling system components from corrosion. These metals include iron, aluminum, copper, lead and other materials that can corrode when exposed to water and other chemicals in the cooling system. As such, whereas color is a good indicator, the specifications on the label is the arbitrator.Ĭoolant comes in contact with a variety of metals in an engine and its cooling system. Importantly, however, although the color is typically associated with the coolant type, there are no industry standards defining the color for each type. As shown in the PQIA Quick Reference Guide, the type of coolant recommended differs by vehicle manufacturer. In short, color typically denote differences in the chemical composition of coolants and its suitability for use in various vehicle make and model years. The different additive chemistries required to address these and other issues, as well as vehicle manufacturer specifications, brings us to the variations in coolant colors. These issues primarily include corrosion, scale, deposits, and aeration/foaming. Whereas the water and glycol mixture provide engine cooling, and freeze and boil over protection, the coolant and the environment in which it operates bring with it additional issues that must be addressed. Along with its ability to lower the freeze point of the coolant, at the other end of the temperature spectrum, ethylene and propylene glycol is also valued for its ability to raise its boiling point.īut there is more. state experience temperatures at or below freezing, although it’s an excellent coolant, water is mixed with another fluid to depress its freeze point (typically ethylene or propylene glycol). If it freezes, it can cause serious damage to the cooling system and engine. But, although it excels in heat transfer, it comes with its own set of issues first it freezes at 32☏. The fluid does so by absorbing the heat of combustion and transferring it to the radiator where it can be dissipated to the surrounding air.ĭue to its outstanding ability to both absorb and transfer heat, water is the fluid of choice for cooling engines. But as those familiar with these fluids know, its primary purpose is to prevent an engine from overheating (remove excess heat). It can be used as a complete service refill, top up and is safe to mix with compatible Type A coolants.This question comes as no surprise since the word “antifreeze” can easily be interpreted as meaning the purpose of the fluid is to prevent a radiator/engine from freezing. It is pre-mixed with Penrite De-Mineralised Water and can be poured directly into the cooling system.
It is also ideal for motorcycles.ģ50,000 KM Green Coolant Premix is a 33% concentration formulation and is ready to use directly from the container. It is effective in all cast iron and aluminium engines that are under load or used in extreme hot and cold climates.ģ50,000 KM Green Coolant Premix may be used in all types of vehicles that use green, blue or yellow coloured initial fill coolants. It protects cast iron, aluminium, copper and solder alloys as well as the hoses, seals and plastics. It provides long-term protection against rust and corrosion for all materials used in the engine and in the cooling system. It is available in concentrate and premix forms.ģ50,000KM Coolant Premix is mixed at a 33% concentration level.ģ50,000 KM Green Coolant Premix is suitable for passenger cars, 4WDs, motorcycles, light & heavy duty commercial vehicles, construction and agricultural equipment It can be used in Australian, European, Asian and US vehicles who specify a Hybrid (HOAT) type anti- freeze anti boil coolant.ģ50,000 KM Green Coolant Premix is suitable for the cooling systems of petrol, LPG, light and heavy duty diesel and industrial engines where Type A anti-freeze / anti-boil and anti-corrosion properties are required.
