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.
