Guys, need help diagnosing an issue. I made a little change to the cooling system - installed in line T for the water temp sending unit. Then I added coolant and bled the system both by the head and the water pump. During my first trip he rhino was about 200. I had to stop all the time and let it cool down. Also every time it would get real hot the reservoir would fill up and shoot coolant everywhere and all over the floor board. I hope that replacing a head gasket would do good. But before that I'd like to run a pressure test on the system to see if it holds. The problem is that I don’t get where the air is coming from unless it was already there from the T installation and I’m not getting it all out. Guys, please help me to figure out what’s wrong because getting to my head is not going to be fun and want to make sure it’s my last option. Thanks!
