94 mpv over heating? i put new rad and thermostat.. there is no coolant flow in the rad and it blows only cold air inside? is the impeller on the water pump broken or worn out? if so,details on water pump install..
You probably never cleaned the cooling system out.
If you have not get it done by pros.
It seems something is blocking the flow. If the water pump went bad you will know. Rarely ever heard a impeller breaks off like you think. The bearings and the seal break first.
Check and see also if the heater valve is working.
As for the over heating even new thermostats fail. Reverse flush is needed or the procan measure the pressure in the radiator cooling system and edetermine if there is a engine pressure problem. Tools and experience is the key in the game of diagnosis.
