COOLING SYSTEM MAINTENANCE
LIQUID 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 from the tank
past the pressure cap and into the radiator.
NOTICE
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.
CAUTION
Overheating of engine could occur if air is not fully
purged from system.
Polaris Premium 50/50 Extended Life coolant is already
premixed and ready to use. Do not dilute with water.
COOLANT STRENGTH / TYPE
Test the strength of the coolant using an antifreeze
hydrometer.
• A 50/50 mixture of extended life 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.
