I don't believe anything is leaking or at least that i can see. It hasn't lost fluid out of the resivoir since I got it a year ago. Do you think it could be the pressure cap? Can you mix Polaris 60/40 with 50/50? I'm thinking the water pump is bad. Anyone else? Thanks everyone

 

I had coolant spewing this winter out of the over-flow bottle, turned out it was the pressure cap. I guess it weakens and drops the pressure in the whole system allowing it to boil over easy. I never had the temp light on with this problem though, but it was cold out too. Its a piece of mind fix though, and the dealer claims they go through a lot of these caps. Only problem is they want $40

 

Could it have air in the cooling system?

 

From Service manual
Low coolant level
Air in cooling system
Wrong type of coolant
Faulty pressure cap or system leaks
Restricted system ( mud or debris in rad fins , passages blocked in rad , lines,pump,or water jacket )
Lean mixture ( restricted jets,vents,fuel pump or fuel valve )
Fuel pump output weak
Restricted radiator ( internal or cooling fins )
Water pump failure
Cooling system restriction
Cooling fan inoperative or turning too slowly ( perform current draw test )
Ignition timing misadjusted
Low oil level
Spark plug incorrect heat range
Faulty hot light circuit
Thermostat stuck closed or not opening fully
Possible loose or missing diverter inside radiator

 

Check the radiator fins.

 

I rode it for about three hours no prob. coolant is above MAX line now though. When i was done riding i let it cool for about 5 hours. Had to go get gas. I rode about half a mile there and back and my fan was already on! I checked the coolant under the pressure cap before i went riding and there was coolant in there. Why is the resivoir filling up? I never added any coolant and it started off between the min and max line when i first bought it. Thanks
