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 50/50 Antifreeze/
Coolant is recommended for use in all cooling systems
and comes pre-mixed, ready to use.
