: After a complete engine overhaul, a new thermostat was correctly installed, (160 degrees), and the tractor would overheat. Another one was put into the water outlet, and the same problem occured. Then I ran the engine without one, just like it was when I purchased it, and it's not over heating now. Can someone give me a idea what my be the problem with this. Thanks!
Sometimes there are large air pockets in the system until coolant circulates evenly. I had that happen in my Vette after I changed the thermostat. My Moline "U" did what you described due to a blown head gasket. It pressurizes the system and causes boilover. Hopefully it's the air pocket instead!
