use a high quality ethylene glycol base anti-freeze, mixed with distilled water. Do not mix an alcohol base anti-freeze and different brands of anti-freeze.
Do not put in more than 60% anti-freeze or less than 50%. (Refer to fig. 1 And 2.)
At the time of manufacture, 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 cooling system from freezing at temperatures above –31 °c (–24 °f).
If the vehicle is to be exposed to temperatures below – 31 °c (–24 °f), this mixing ratio should be increased up to 55% or 60% according to the figure.
