8. Mix the recommended antifreeze with an eoualamount of water in a clean container.
NOTE:
o Use only genuine Honda antifreeze/coolant.. For best corrosion protection. the coolant con_centration must be maintained year_round at50% minimum. Coolant concentrations less than50% may not provide sufficient protectionagainst corrosion or freezing.. Coolant concentrations greater than 60010 willimpair cooling efficiency and are not recom_mended.
CAUTION:
. Do not mix difforont brands ofar ilreeze/coolants.. Do not use additional rust inhibiiors or anti_rustproduqt3; they may not be compatible with thecoolant.
