Universal 50/50 premix antifreeze/coolant is a superior quality ethylene glycol based engine coolant with a low silicate corrosion inhibitor package. This product protects coolant system metals, including heat-rejecting aluminium, against pitting caused by cavitation and corrosion. It provides protection against radiator freeze-up down to -37°C and boil over to 129°C. It is recommended for use in older model domestic and foreign cars and light duty trucks and will provide up to 80000 km or 2 years service life when installed as initial fill or after a complete flush and cleaning of a cooling system in reasonable condition. It is compatible with supplemental coolant additives (SCA) and coolant filters and thus can be used in heavy duty diesel coolant systems when pre-charged with SCA.
