I have a kawasaki mule 3010 with the vtwin gas motor.. Now there is coolant in the heads which of course makes me think that it is a bad head gasket but now it is running better then ever since i have had it.. The symptoms are excessive smoke under load.. Not nesccically when idling in neutral as much but as soon as i put it in drive it will start to smoke a good amount through the tail pipe and when driving of course it will smoke even more.. Now it runs great for anywhere from 5-15 minutes at MOST but then starts to heat up to about 240 or more... The radiator will be full one minute then bone dry the next which i guess could be cause it is all going into the cylinder and heads but tge overflow tank will be completely filled all the way to the rim when the maximum full amount shows to be less then half way up.. The symptoms it is having seem like it could also have bad blow by due to worn out cylinder rings amd possibly the cylinder sleeves themself.. What do you think might be going on? Thank you in advance
