Sounds like two diffrent problems ,but the leaking of the coolent could be radiator ,bad hose or thermostat .If the oil is leaking it might have a sensor so you dont blow the motor ..I hope this helps ..If any thing please call local Polaris dealer so no futher damage ..Have a great xmas !

My Sportsman runs bad when heated up, but if you add fuel it runs fine again. I had a pick up that had an internal fuel pump like our Sportsman's and it did the exact same thing. It turned out being the fuel pump was worn out due to a plugged fuel filter. Forcing the pump to fail prematurely. I found I had bad fuel in my Sportsman and am going to replace the filter and the fuel pump. I also checked my plugs, MAF sensor, and Air filter, they were fine.

you probly need a new heat sensor, its located on the bottom right of your rad, i had the same problem with my 700 the fan only worked when it was already over heating, i cut the wires flush at the sensor drilled a hole above the key switch and mounted a toggle switch, no more over heating,

I have a 2006 Sportstman 500HO ATV, EFI. Sometimes it will run 100% correct, other times it will start, idle fine but then when giving it throttle will will start to surge almost like it's hitting a rev limited. Sometimes it will backfire and stall. I already replaced fuel filter, flushed the fuel lines and gave it fresh gas and installed a new spark plug, but no good. I also checked the throttle switch and it's not making contact to stall it. I download the service manaul and tested each sensor and they tested fine which is probablt why I get no check engine light.
This ATV is mainly used to plow snow in my driveway, no salt. It's used around my property but very lightly. It's still as clean as it was when I bought it and it doesn't have but about 40 hours on it.
