I am hoping that someone can point me in the right direction on this issue. I have a 2011 MXZ 600 Sport. I just replaced the oil filter and coolant on the machine. Now the machine won't start unless it is completely cool. It fires up instantly when at ambient temperature, but if I shut the machine down for even a minute and try to start, it just cranks (electric start). It doesn't give a hint of starting. Even if I let it sit for 15 minutes, it won't start. The engine needs to cool down completely before it will start again. I must have caused the problem when I pulled the oil tank to change the oil filter. Not sure how replacing the coolant would have caused this. Any help would be appreciated.
