• The upper limit of the LLC concentration is 60%
for GLASSY and 90% for PG GLASSY. If the
concentration is higher than above, the
antifreeze effect will be lowered, or the coolant
temperature will be increased due to the lowered
specific heat.
• The coolant temperature increases by
approximately 1.5°C [2.7°F] for GLASSY at 60%
concentration and by approximately 3°C [5.4°F]
for PG GLASSY at 90% concentration. Check
heat exchanger capacity of the cooling system to
avoid overheating.
