The return hose is 5/8 on the 60's Imperials I have a feeling
that is how some folks get the idea to use a length of heater hose, since
it fits right on & they know the cooling system gets pretty hot &
operates under pressure.
The problem here is that a heater hose won't
stand up to the fluids in the steering & start to slough off from inside
& depositing a lot of garbage throughout the system. Generally, by the time
you notice something wrong, the damage has been done.
