NOTICE
If temperatures consistent ly below -22°F (-30°C) are
expected, the coolant mixture should be changed to
a higher concentration. Cons ult a dealer for more
information.
If Honda antifreeze /coolant is not available, you may
use another major brand non- silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda antifreeze/coolant as soon as
possible.
