GRRRRR! Water pump??? Replaced thed the thermostat housing (water outlet) and the glue started to come apart again due to heat.
Water pump is not leaking and there is no slop in the fan (bearings). Could the water pump not be pumping? Could the fins be as small as tick tacks and not be pushing any water? Very late...gonna get an early start again tomorrow. Going to start a new thread and listen for ideas.
Thanks fellas!

 

flush the radiator and check flow thru the motor and passages.
