8.Mix the recommended antifreeze with an equal
amount of water in a clean container.
NOTE:
a Use only genuine Honda antifreeze/coolant.
a For best corrosion protection, the coolant concen-
tration must be maintained year-round at 500,6
minimum. Coolant concentrations less than 507o
may not provide sufficient protection against cor,
rosion or freezing.
a Coolant concentrations greater than 60% will im-
pair cooling efliciency and are not recommended.
CAUTION:
a Do not mix different brands of anti-lrcezel
coolants.
a Do not use additional rust inhibitots or anti-tustproducts; they may not be compatible with the
coolant.
