Recommended Coolant
Use only high quality antifreeze/coolant mixed with
distilled water in a 50/50 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.
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 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.
