G13 is an ethylene glycol/glycerine based extended life antifreeze/coolant that combines the fast healing aluminum protection associated with silicate additives with the extended cooling system protection of organic acid technology. When mixed in the recommended ratio with distilled or demineralized water, its chemical inhibitors protect engine coolant passages, radiator, water pump, and cooling system pipes from corrosion damage.

It is both nitrate and phosphate free and compatible with engine gaskets and seals.

Note: This is pure antifreeze that must be mixed 50/50 with water, preferably distilled or de-mineralized, for best results.
