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.

3. The system must maintain 10 psi for five minutes or longer.
If pressure loss is evident within five minutes, check the
radiator, hoses, clamps and water pump seals for leakage.
Pressure Cap Test
1. Remove the front hood (see Warning under "Cooling
System Pressure Test").
2. Remove pressure cap and test using a pressure cap tester
(commercially available).
3. The pressure cap relief pressure is 13 psi. Replace cap if it
does not meet this specification.
