MAINTENANCE
G. COOLING SYSTEM
Coolant
Fill the radiator with soft, pure tap or bottled water.
Anti-rust agent
Add approximately 0.8 L (0.8 US qt) of anti-rust agent to the
new coolant when the coolant is changed.
It is not necessary to add anti-rust agent when antifreeze is
used.
Antifreeze
If the air temperature is expected to fall below 0°C (32°F), fill
the cooling system with an antifreeze and soft water mix. As
a general rule, the ratio of antifreeze should range between
30% and 60% as shown in the table below. If the ratio is
below 30%, the system may develop rust, and if it is above
60%, the engine may overheat.
