Remove the plastic, Run it till coolant comes out, find exactly where its coming from... Then i would go from there..

Also crank the engine with the radiator cap off if coolant starts to shoot up it could be a blown head gasket.. Inspect your radiator for cracks etc, Check all hoses, if all that checks out good then its down to your water pump and thermostat or your pressure cap(check to see if its coming out there)..

Also does your fan turn on during this time?

 

Also a service manual would come in handy... You can get one at your dealer. I paid 35 for mine...

 

Test the thermostat in an pan of water. Heat the water and moniter it with a thermometer. If it opens at or near the rated temperature its ok. If it doesnt, Polaris wants about $90.00 for one in Dayton Ohio. Good luck.
