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 tank past the pressure cap and into the radiator.
NOTE: Some coolant level drop on new machines is
normal as the system is purging itself of trapped air.
Observe coolant levels often during the break-in
period.
NOTE: Overheating of engine could occur if air is
not fully purged from system.
IMPORTANT: Polaris Premium 60/40 Antifreeze is
already premixed and ready to use. Do not dilute with
water.
Coolant Strength
Test the strength of the coolant using an antifreeze hydrometer.
Antifreeze Hydrometer
• A 50/50 or 60/40 mixture of antifreeze and distilled
water will provide the optimum cooling, corrosion
protection, and antifreeze protection.
• Do not use tap water, straight antifreeze, or straight
water in the system. Tap water contains minerals and
impurities which build up in the system.
• Straight water or antifreeze may cause the system to
freeze, corrode, or overheat.
Recommended Coolant:
Polaris Premium Pre-Mixed Antifreeze
(PN 2871534) (Quart)
(PN 2871323) (Gallon)
