I accidently posted this in auto so here I go again! I am working on a Kawasaki Mule 3010 with the FD620D motor. It was brought over because of a leaking water pump. I replaced the water pump, rebuilt the carb and replaced the thermostat. Filled it with coolant and began the long task of bleeding bubbles from the system. After many hours of bleeding and believing they were all out, started the machine and let it idle, with the radiator cap off. water slowly started running out of the radiator, so I kept adding coolant until the thermostat opened, which immediately drained the radiator completely! I shut the machine off and filled the radiator, jacked up the machine and bled it again. I bled every hose and line separately on the engine to make sure. This time, I put the radiator cap on and started it. All seemed fine for about 10 minutes of idling so I drove it down the street and back. Once I got back I noticed I left a trail of coolant the whole way down the street and back. What? So I refilled everything yet again, bled it again and started it and let it idle. After about 20 minutes of running, I noticed the coolant in the overflow tank rising until it began pouring out! In just a few minutes, it had blown all the coolant from the machine out through the overflow. Bad head gaskets? Did a compression test and it showed 210 and 190. Oil looked fine with no water in it. What is going on? PLEASE help, I have 10 pus hours just bleeding this thing and I don't know what to do next. Any ideas? Also, I did flush the entire system prior to filling and bleeding. Thanks in advance!
