MAINTENANCE
11. Coat terminals and bolt threads with Dielectric
Grease (PN 2871329).
12. Reinstall battery cover and holder strap.

Cooling System

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.
• 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.
• Overheating of engine could occur if air is not fully
purged from system.
• Polaris Premium 60/40 anti-freeze is 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 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.

Cooling Hoses

Inspect all hoses for cracks, deterioration, abrasion or
leaks. Replace if necessary.
1. Check tightness of all hose clamps.
2. Do not over-tighten hose clamps at radiator or
radiator fitting may distort, causing a restriction or
leak.

Radiator

1. Check radiator external air flow passages for
restrictions or damage.
2. Carefully straighten any bent radiator fins.
3. Remove any obstructions with compressed air or low
pressure water.

Cooling System Pressure Test

See Chapter 3 for pressure test procedures.
