JFranklin Posted July 6, 2017 Share Posted July 6, 2017 (edited) A new engine will normally run a bit hot till broken-in. If you have a new radiator and no thermostat it shouldn't boil over. If it is not boiling don't worry about it. Retarded timing or lean fuel mixture & maybe a bad head gasket are about the only other engine problems to cause overheating, otherwise check to make sure the brakes are not dragging.
