2. The fluid level should be 0.75 in. (1.9 cm) from the bottom
of the fill plug hole threads. Use a light colored and non-
absorbent measuring instrument (white zip tie) to measure
the depth of the fluid in the rear gearcase. If level is low,
add ATV Angle Drive Fluid (PN 2871653).

COOLING SYSTEM

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 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.
Overheating of engine could occur if air is not fully purged from
system.
Polaris Premium 60/40 is already premixed and ready to use. Do
not dilute with water.
