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.
WARNING
Never remove pressure cap when engine is warm or
hot. The cooling system is under pressure and serious
burns may result.
Allow the engine to cool before servicing.
2. Remove pressure cap and pressure test the cooling
system using a commercially available tester.
3. The system must maintain 10 psi for five minutes. If
pressure loss is evident within five minutes, check
radiator, hoses, clamps and water pump seals.
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.
