COOLING SYSTEM
COOLING SYSTEM OVERVIEW
The engine coolant level is controlled, or maintained, by
the recovery system. The recovery system components
are the recovery bottle, radiator filler neck, 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 recovery
bottle. As engine coolant temperature decreases the
contracting (cooled) coolant is drawn back up from the
bottle, past the pressure cap, and into the radiator.
NOTE
Some coolant level drop on new vehicles is normal as
the system is purging itself of trapped air. Observe
coolant level often during break-in period.
CAUTION
Overheating of engine could occur if air is not fully
purged from system.
Polaris recommends the use of Polaris Premium 50/50
anti-freeze or a 50/50 mixture of high quality aluminum
compatible anti-freeze/coolant and distilled water.
NOTE
Polaris Premium 50/50 Antifreeze is already premixed
and ready to use. Do not dilute with water.
COOLANT LEVEL INSPECTION
The pressure cap and recovery bottle are located
underneath the front rack and Storage tray as shown
below. Maintain the coolant level between the “MIN” and
“MAX” levels indicated on the recovery bottle.
With the engine at operating temperature, the coolant
level should be between the MAX
q
and MIN
w
marks on
the coolant recovery bottle. If not, perform the following
procedure.
1. Position the vehicle on a level surface.
2. View the coolant level in the recovery bottle. The
coolant level can be viewed from inside the front right
wheel well.
3. If the coolant level is below the “MIN”
w
line on the
bottle, remove the front rack assembly to access the
radiator pressure cap and recovery bottle cap.
NOTE
If overheating is evident, allow system to cool
completely and check coolant level in the radiator and
inspect for signs of trapped air in system.
WARNING
Never remove the pressure cap when the engine is
warm or hot. Escaping steam can cause severe burns.
The engine must be cool before removing the pressure
cap.
4. Remove the pressure cap. Using a funnel, add
coolant to the top of the radiator filler neck.
5. Reinstall the pressure cap.
NOTE
Use of a non-standard pressure cap will not allow the
recovery system to function properly.
6. Remove recovery bottle cap and add coolant using a
funnel.
7. Fill recovery bottle to “MAX”
q
level with Polaris
Premium 50/50 antifreeze /coolant or a 50/50 mixture
of antifreeze/coolant and distilled water as required
for freeze protection in your area.
8. Reinstall the recovery bottle cap.
