COOLANT STRENGTH / TYPE
Test the strength of the coolant using an antifreeze
hydrometer.
Antifreeze Hydrometer
G A 50/50 or 60/40 mixture of Polaris
PremiumCoolant (PN 2871323) and
distilled water will provide the
optimum cooling, corrosion
protection,andantifreezeprotection.
G Do not use tap water. Tap water
contains minerals and impurities
which build up in t he system. Do not
add straight antifreeze or straight
water to the system. Straight water
or antifreeze may cause t he system
to freeze, corrode, or overheat.

COOLING SYSTEM HOSES
1. Inspect all hoses for cracks, deterioration,
abrasion or leaks. Replace if necessary.
2. Check tightness of all hose clamps.
CAUTION: Do not over-tighten hose clamps at
radiator, or radiator fitting may distort, causing a
restriction to coolant flow. Radiator hose clamp
torque is 36 in. lbs. (4 Nm).
