MAINTENANCE
Cooling System
Coolant
The coolant supplied in the system at the factory is a 50/50 mixture of
ethylene-glycol and distilled water, which will provide adequate freeze
protection under most conditions. If the vehicle will be stored or oper-
ated at extremely low temperatures, greater protection may be required.
Please see your Polaris dealer.
When adding or changing coolant, Polaris recommends using Premium
60/40 anti-freeze coolant, which is already premixed and ready to use.
Do not dilute with water. Never exceed a 60% antifreeze/40% water
mixture. See page 125 for the part numbers of Polaris products.
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 a switch in the
engine cooling system on liquid cooled models. If the engine coolant
reaches a certain temperature, the switch 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.
