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

MAINTENANCE
Cooling System
Coolant High Temperature Indicator Light
The high temperature indicator light will illuminate when engine
coolant temperature becomes too hot for safe continued operation of the
engine. If you must drive your machine after the high temperature
indicator 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. 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, we
recommend that the system be completely drained every five (5) years
and fresh Antifreeze 50/50 Premix added. 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.
