The cooling system is filled with a 50:50 mixture of distilled water and ethylene glycol anti-freeze. This 50:50
mixture will provide the optimum corrosion protection and excellent heat protection, and will protect the cool-
ing system from freezing at temperatures above –31 °C (–24 °F). If the vehicle is to be exposed to tempera-
tures below –31 °C (–24 °F), this mixing ratio should be increased up to 55% or 60% according to the figure.
