I have a ‘78 Midget 1500 with a rebuilt engine (less than 1000mi) and my temp guage tends to indicate overheat after 40min or so of driving. I’ve flushed the system, replaced the thermostat & sender unit, checked for manifold & gasket leaks and have no indication there’s anything wrong there. When the temp needle gets to just the edge of the red zone on the guage the temp at the thermostat housing (measured by laser thermometer) ranges between about 165-175 degrees and the block between 175-180. I’m tempted to believe the guage is boggled. The car has never boiled over or pushed coolant into the overflow tank.
Does anyone know what the operating range is for temperature? I’m planning on driving the car locally and keeping an eye on things but would like to know how hot is “too hot”.
Thanks,
Gregg
