After putting around 15 hours on the RZR know it is pushing water out the over flow bottle,replaced the fan relay because it was not running the fan very long and sometimes not at all,this did not cure the problem,it only pushes out what the bottle holds,its not over full because when it cools the bottle is still empty,I notice that when it is blowiing water out ,that the fluid in the hose that goes from the top of radiator on the left side to the right side below the fill cap has alot of air bubbles and looks foamy,any ideas on whats causing this,will be taking it back to the dealer this week,just looking for some input from yall.

My educated guess is that there is air in your system and needs to be bled out. There is a coolant bleed screw on the thermostat housing on the passenger side of the engine (forward side). It helps to have your front end jacked up too. Check the service manual and/or owners manual on how to bleed the cooling system.

LOL.. well.. if the head gasket is leaking, pressure from the cylinder can get into the cooling system and push it out the overflow.

but I don't think it would empty the bottle.. it would fill it..

Try bleeding the system. When I drained my system to replace the coolant with Engine Ice, mine would shoot water out of the overflow pinhole until the system was thoroughly bled of any air.
Will do,give me the scoop on Engine Ice,purpose and advantage.

X2. Sounds like air in the system. Lifting the front does help.

Engine Ice keeps the coolant at a lower temp, which means less time with the fan running. Works really well, I barely hear my fan come on any more and I run usually between 180 and 200 degrees, even at slow speeds. I also have the Polaris "hood scoop" hood, which improves airflow to the rad. A forum search for Engine Ice will give you lots more info. It's not an additive, the whole system needs to be thoroughly flushed and Engine Ice is used straight up.

the thermostat is on the front of the engine behind the passenger seat. there is a screw on it that you can use to bleed the air out.

Man I think you nailed it on the air in the system,went out to check it and backed the bleed screw out and air started blowing out,waited till it stopped and and checked the level in the radiator and now it is low,will pick up some antifreeze tomorrow and fill and test the system,and I did have the RZR sitting on a incline while bleeding.YOU DA MAN.
