Pub. No. K29001-00320 Revision: 1

• 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.
