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
WARNING
Never remove radiator cap when engine is
warm or hot. The cooling system is under
pressure and serious burns may result. Allow

neck.
3. Connect a Mity Vac
t
( PN 2870975 ) to the filler
neck nipple and pressurize system to 10 psi. The
system must retain 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.
