My 1997 caddy started to over heat.
I replaced the radiator, water pump and thermostat.
Fans kick on at the right temp both high and low.
I do not see white smoke coming from the tail pipe.
When engine was cold I ran water through up and lower line of the hose
I have ran water through upper and low side of engine to look for blockage
I have removed thermostat at this point connected all line filled cooling system with water
and started motor.
after starting motor and letting it run for a while I can feel that upper radiator hose get hot but No water flow
lower hose I feel water flow going through. I am stumped
