12-2 General Information

Warning:

Never attempt to open the radiator filler cap while the engine is running. The pressurized hot

coolant may escape and cause serious scalding injuries. Do not perform maintenance unless

the engine is completely cooled down.

• Refill the radiator only with distilled water and anti-freeze solution.

• Add coolant to the reservoir only.

• The cooling system can be serviced while installed on the ATV.

• Never spill the coolant onto painted surfaces.

• Test the cooling system for any leaking after the repair.

• Refer to Section 17 for inspection of the temperature sensor switch for the fan motor

and the water thermometer.
