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.
Cooling System Pressure Test
1. Remove the hood from the front cab.
