MAINTENANCE
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.
When the coolant is cold the coolant level should not exceed the cold fill
line on the side of the tank.
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 page 130 for the part numbers of POLARIS products.
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. See page 99 for changing
procedure.
Any time the cooling system has been drained for maintenance or repair,
replace the coolant with fresh Antifreeze 50/50 Premix.
