Cooling System
The engine coolant level is maintained by the recovery system. The
recovery system components are the overflow bottle, radiator vent
fitting, radiator pressure cap and connecting hose.
As coolant operating temperature increases, the expanding (heated)
excess coolant is forced out of the radiator, past the pressure cap, and
into the overflow bottle. As engine coolant temperature decreases, the
contracting (cooled) coolant is drawn back up from the tank, past the
pressure cap, and into the radiator.
Tip: Some coolant level drop on new vehicles is normal as the system is purging
itself of trapped air. Observe coolant levels and maintain as recommended
by adding coolant to the overflow bottle.
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 140 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 103 for changing
procedure.
Any time the cooling system has been drained for maintenance or repair,
replace the coolant with fresh Antifreeze 50/50 Premix.
