Puk'in Fluid

Found it!! Replaced water pump, drilled bleeder hole in thermostat, added another electric fan for increased cooling air, watch carefully for out-gassing in water (nothing), and same results again. Just for s#!+$ & giggles shot the temp gun on bottom tank of radiator at 103* and top was 195*. Seems that one of the last run-ins had something in the engine that has gelled in the radiator. Easy to replace. Thanks to all for hints, suggestions, and advice. I am done guessing on this one.
