Coolant Mixture
The coolant supplied in the system is a 50/50 mixture of
ethylene-glycol and distilled water. This mixture provides protection
against freezing at temperatures to -34° F (-37° C). If greater
protection is required, the percentage of antifreeze to water may be
increased. Use Premium 60/40 anti-freeze coolant, which is already
premixed and ready to use. Do not dilute with water. See page 128 for
the part numbers of Polaris-recommended products.
Never exceed a 60% antifreeze/40% water mixture. Contact you dealer
if greater protection is required.
NOTE: Never add tap water to the cooling system. Minerals cause
deposits and may react adversely with the metals in the engine and
cooling system.
Coolant High Temperature Indicator Light
The high temperature indicator light is controlled by the electronic
control unit (ECU). If the engine coolant reaches a certain
temperature, the ECU completes a circuit that turns the light on. If
you must drive your machine after the high temperature indicator light
has come on, drive slowly and stop frequently to allow the engine to
cool down. See your dealer.
