ENGINE COOLING SYSTEM
Cooling System Specifications
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.
2. Remove pressure cap and pressure test the cooling
system using a commercially available pressure
tester.
3. The system must maintain 10 psi for five minutes or
longer. If pressure loss is evident within five minutes,
check the filler neck, radiator, hoses, clamps and
water pump weep hole for leakage.
