2019 RZR Tipover

Well, I finally did it 115 miles on the RZR, we were going up a slick, technical, and steep mountain trail, conditions got gnarly and we ended up flopping the rzr on its side. It sat there for about 2 hours while we tried to get other wheelers and additional help, I got it upright on flat ground and let it sit for about 20-30 minutes. Once I started it white smoke plumed out from the oil burning, it lasted about 5 minutes and I noticed it was overheating. The oil was low, and I need to change it, but no apparent sounds of engine damage. The resivior is about a 1/4” about the cool fill line, and all hoses and radiatiors are cold to the touch. Temp got to about 220° and up to 240° once trying to limp it to the trailer,

Any ideas? Oil, air in the line, pump gone bad, thermostat?
