Cooling System Specifications
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, ready to use.
