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.
