Upper rad. hose outlet broke so I
used epoxy for a quick fix Could I
leave the thermostat out so
there's no pressure, until I can get
another radiator ?
It’s not the thermostat that causes pressure, it’s the radiator cap and the normal expansion of the coolant when it warms up. And no you can’t run without a radiator cap.
Ok third one not posting answers. I’m done for the day.
