Flushing The Cooling System - Polaris 600 HO IQ Owner's Manual

Cooling System
Coolant High Temperature Indicator Light
Steam and hot liquids will cause serious burns to your skin. Never remove
the pressure cap when the engine is warm or hot.
The high temperature indicator light will illuminate when engine cool-
ant temperature becomes too hot for safe continued operation of the
engine. If you must drive your machine after the high temperature indi-
cator light has come on, drive slowly and stop frequently to allow the
engine to cool down. Driving in deep snow will also help cool the
engine. See your dealer for service. Add coolant if the level is low.
NOTE: Engine performance will be reduced if you continue operating
when the high temperature light is on.

Flushing the Cooling System

To ensure that the coolant maintains its ability to protect the engine,
drain the system completely every two years and add a fresh mixture of
antifreeze and distilled water. This service must be performed when the
engine is cold. Ask your Polaris dealer to check the coolant when he
performs the fall tune-up on your snowmobile.
