Hi I have a ’14 rzr 900. I can start it up let it idle it is fine…I can drive it under 40 mph it is fine….if you have to.get on it to go.up a hil or go faster than 41 mph it overheats immediately. Ive cleaned the radiator..replaced thermostate biught a higher pressure radiator.cap…still does this.same thing….amen it is acting normal the radiator is nice and warm and temps stay between 178 and 188 easily. If it does get to 199 the can will kick on and it cools down as it should…amen u go over 40 ite give it a decent amount I’d gas to raise the rpms…the radiator instantly becomes cold and the fluid shoots or of the overflow lid…..if anyone has any idea as to.what could be going on please help…also I’ve bled the cooling system each time it overheats
