How to Cool a Snowmobile Engine


If your engine is overheating on your snowmobile, promptly take action to cool the engine. This can be done by:

  • Driving in loose snow.
  • Viewing the coolant level. If it is low, add coolant. DO NOT open the pressure cap while the engine is hot.
  • Stopping the engine and allowing it to cool down.
  • Ensuring the radiator(s) (cooler) is clean and free of debris.


If you must continue to operate your snowmobile, drive slowly and stop the engine frequently to allow it to cool down.


Some snowmobiles will send an error code when the engine overheats.


If engine overheating seems to be caused by something other than poor cooling conditions, contact a RideReady Service dealer for assistance.
