Coolant
Coolant specification
The machine is originally filled with Long Life Coolant
(non-Amin type ethylene glycol) which need not be
replaced for the first two years or 3,000 hours.
Do not use Amin type Long Life Coolant in cooling sys-
tem. It may cause a corrosion against radiator or heater
core.
If standard antifreeze (not Long Life Coolant) is used for
the replacement, it should be replaced every six
months.
Recommended mixture of antifreeze
(S/N 9001~9150)
(S/N 9151~)
- Too much antifreeze in the coolant mixture may
cause engine overheating.
Keep 33% antifreeze mixture (same as the mixture
for a minimum ambient temperature of -15°C (5°F)) if
the engine overheats in a high ambient temperature.
- Do not use hard water or water with high levels of
calcium and magnesium ions as the coolant water.

IMPORTANT
Do not mix different brands of antifreeze because
they each contain special additives.
Careless mixing often diminishes the effect of these
additives that causes the packing damage or water
leakage.
