Why Antifreeze / Coolant ?

Antifreeze / Coolant properties prevent the engine from freezing or overheating, providing optimal performance even in the harshest conditions. Areas in Australia where temperatures are in the extremes such as the Snowy Mountains, Tasmanian Highlands and any where else where prolonged periods (over 3 consecutive days and nights) of sub zero temperatures may be experienced require antifreeze / coolants to keep the engine running smoothly.  If operating in an environment that doesn't experience such condition consideration should be given to a type B non anti-freeze coolant such as PrixMax RCP Platinum which has the ability to keep an engine running cooler in the much hotter parts of Australia.  For more information about this please the link below to learn more about non anti-freeze coolants and their benefits.
