COOLING SYSTEM
The engine coolant level is maintained by a remote pressurized tank system.
The remote pressurized tank is connected to both radiators and provides a
single pressure cap and fill point for the vehicle.
The pressure tank is designed to contain a volume of air above the coolant level.
As coolant operating temperature increases the coolant level in the pressure
tank will rise and push out air past the pressure cap. As the engine coolant
temperature decreases the coolant level in the pressure tank will lower and draw
air back into the tank through the pressure cap.
TIP
Some coolant level drop on new vehicles is normal as the system is purging
itself of trapped air. Observe coolant levels and maintain cold coolant level as
recommended by adding coolant to the pressure tank.
CAUTION
Escaping steam can cause burns. Never remove the pressure cap while the
engine is warm or hot. Always allow the engine to cool before removing the
pressure cap.
ADDING OR CHANGING COOLANT
POLARIS recommends the use of POLARIS Antifreeze 50/50 Premix. This
antifreeze is already premixed and ready to use. Do not dilute with water. See
the Polaris Products section for the part numbers.
To ensure that the coolant maintains its ability to protect the engine, we
recommend that the system be completely drained every five (5) years and fresh
Antifreeze 50/50 Premix added.
Any time the cooling system has been drained for maintenance or repair,
replace the coolant with fresh Antifreeze 50/50 Premix.
RADIATORS AND COOLING FAN
Always check and clean the screens and radiator fins at the intervals outlined in
the Periodic Maintenance Chart section. Do not obstruct or deflect air flow
through the radiators by installing unauthorized accessories in front of the
radiators or behind the cooling fan. Interference with radiator air flow can lead to
overheating and consequent engine damage.
NOTICE
Washing the vehicle with a high-pressure hose could damage radiator fins and
impair a radiator's effectiveness. Using a high-pressure system is not
recommended.
