CONTROL AND PARTS FUNCTIONS
Engine Cooling System
Coolant Level
The recovery bottle, located on the
left side of the machine, must be
maintained between the minimum
and maximum levels indicated on the
recovery bottle.
The engine coolant level is controlled
or maintained by the recovery sys-
tem. The recovery system compo-
nents are the recovery bottle, radia-
tor filler neck, radiator pressure cap
and connecting hose.
As coolant operating temperature in-
creases, the expanding (heated) ex-
cess coolant is forced out of the ra-
diator past the pressure cap and into
the recovery bottle. As engine cool-
ant temperature decreases the con-
tracting (cooled) coolant is drawn
back up from the tank past the pres-
sure cap and into the radiator.
NOTE:
Some coolant level drop on
new machines is normal as the sys-
tem is purging itself of trapped air.
Observe coolant levels and maintain
as recommended by adding coolant
to the recovery bottle. Polaris recom-
mends the use of Polaris Premium
60/40 anti-freeze/coolant or a 50/50
mixture of high quality aluminum
compatible anti-freeze/coolant and
distilled water.
NOTE:
Polaris Premium 60/40 is already premixed and ready to
use. Do not dilute with water.
NOTE:
Always follow the manufacturer’s mixing rec-
ommendations for the freeze protection required in your area.
To access the recovery bottle on Gen IV machines it is necessary to remove the
left side panel as described on page 91.
