RECOMMENDED COOLANT
Use only high quality antifreeze/coolant mixed with
distilled water in a 50/50 or 60/40 ratio, depending on
freeze protection required in your area. CAUTION:
Using tap water in the cooling system will lead to a
buildup of deposits which may restrict coolant flow and
reduce heat dissipation, resulting in possible engine
damage. Polaris Premium 60/40 Antifreeze/Coolant is
recommended for use in all cooling systems, and comes
pre-mixed and ready to use.
