2009 Skidoo MXZ 800r 6000 Miles. As i was riding across the lake the other day, my sled started to overheat and coolant was spitting out of the overflow hose. After further investigation i found that my heat exchanger was only hot on one side and ice cold on the other side. Towed the sled back to the hotel and lifted up the front end to try and burp any air bubbles that may be in the line but no matter how many times we tried it when taking the cap off and running the sled after about 25 seconds the coolant is over flowing right from the bottle and still coming up as overheating on the dash with the 'ENGINE' coming up across the screen as well. Ive been looking for the bleed screw but see nothing on top of the head and even anywhere around the thermostat?
