Cooling System Overview
The engine coolant level is controlled, or maintained, by
the recovery system. The re covery system components
are the recovery bo ttle, radiator filler neck, radiator
pressure cap and connecting hose.
As coola nt op erating tem perature in creases, the
e
xpanding (heated) excess coola nt is for ced 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 tank past the
pressure cap and into the radiator.
NOTE: Some coolant level drop on new machines is
no
rmal as the system is purging itself of trapped air.
Observe coolan t lev els of ten during the brea k-in
period.
NOTE: Overheating of engine could oc cur if air is
no
t fully purged from system.
Polaris Premium 60/40 is already premixed and ready to
us
e. Do not dilute with water.
Coolant Level Inspection
The pressure cap and recovery bottle are located under
the front hood of the vehicle. The coolant level must be
maintained be tween th e min imum and ma ximum le vels
indicated on the recovery bottle.
With the en gine at o perating temp
erature, the coolant
level should be between the upper and lower marks on the
coolant re covery bo ttle. If no t, per form the fo llowing
procedure:
1. Position the vehicle on a level surface.
2. Remove the hood from the front cab.
3. View the coolant level in the recovery bottle.
4. If the coolant level is below the MIN line, inspect the
co
olant level in the radiator.
NOTE: If o verheating is e vident, allow system to
cool comp
letely and ch eck coolant leve l in th e
radiator and inspe ct f or s igns of trapped a ir in
system.
5. Remove the pr essure ca p. Using a funnel, ad d
c
oolant to the top of the filler neck.
6. Reinstall the pressure cap.
NOTE: Use of a non-standard pressure cap will not
allo
w the recovery system to function properly.
7. Remove recovery bottle cap and add coolant using a
fu
nnel.
8. Fill recov ery bottle to M AX
level w ith Polaris 60/40
premix Anti Freeze/Coolant or 50/50 or 60/40 mixture
of antifreeze and distilled water as required for freeze
protection in your area.
9. Reinstall the recovery bottle cap.
10. If co olant was re quired, sta rt eng ine an d check for
leaks. Ma
ke su re radiator fins ar e clea n to pre vent
overheating.

Refer to Ch apter 3 fo r co oling sy stem pressure tes t
procedure.
Recovery Bottle
Pressure Cap
Never remove the pressure cap when the
engine is warm or hot. Escaping steam can
cause severe burns. The engine must be cool
