Heater control valve works properly and the core is not plugged as water flow freely thru it. Seems to me if it had air in the system it would overheat. The last thermostate was installed 8000 miles ago. I would think all of the air has been burped out by now. I use a laser beam digital point and shoot thermometer gun to determine the water temp at many places on the motor, heads and radiator and hoses. Has always been below what you would call normal ever since the manifold gasket change.
No return hose to the radiator Billy. But I do agree that the system needs a restriction to slow down the water flow, keep it in the block longer to get hotter.
Has a new 3 week old cap on it. An OEM 16lbs cap that I pressure checked so I know it holds proper pressure.
I appreciate the ideas and thoughts, please keep them coming.
