can't keep 400 polaris cool
hey guys and gal's ,
I can't get any help from the polaris guys. I was wondering if any of you motor heads can help me. after about 20 minutes of riding my 400 starts to loose power and overheats. This is what I have tried so far but I must be missing something.

I have checked for flow (that's ok) Have checked level of colant(ok) checked both lines in and out of engine/rad. (ok) and have bled out the system with that pee hole on top of head. (just let colant come out and closed ) I have also checked for air bubble in rad while the machine was cool to see if I had a cracked head.(looks ok)
any Ideas? Thanks

Yes, those fins can get all mucked up and not allow any air flow through....take the front grill cover off and take a water hose (nothing high pressured) and just keep spraying (preferably back to front) until it run clear....I spend a good 5 minutes on my radiator after I've been riding through mud bogs...

Thanks for all replys. I have not done anything to the engine it's all stock.
the only thing different was I took the machine from 8600 feet to 11500.
The more I think about it the more I think it's the fan. does anybody know how to check the sensor to the fan?
