1Engine Coolant
NOTICE
You will need a more concentrated coolant if you are
driving in extremely cold temperature below −31°F
(−35°C). Consult your Honda dealer for details about
a suitable coolant mixture.
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.
Do not add rust inhibitors or other additives to your
vehicle's coolant system. They may not be compatible
with the coolant or with the engine components.
