Product Barcode

Zerex G48 Antifreeze/Coolant is a premium ethylene glycol-based, phosphate-free Hybrid Organic Acid Technology (HOAT) coolant designed to protect aluminum and other cooling-system metals against corrosion, scale, deposits, freezing, and boil-over.

Its low-silicate G48 formulation is suitable for applications requiring the G48 coolant specification and is designed to protect radiators, water pumps, seals, hoses, and other cooling-system components.

For aviation applications, Valvoline/Zerex Glysantin G48 is specifically listed in Diamond DA40 D documentation as an approved radiator-protection coolant option, making it relevant for select liquid-cooled Diamond aircraft installations. G48-type coolant is specified or recommended in numerous liquid-cooled aviation applications, including select Rotax-powered aircraft. Always verify coolant requirements against the applicable aircraft and engine maintenance documentation before use.
