I have a 77 F250 with 351Engine and is 4 X 4. It has been sitting for years
just being started to keep things in working condition. The male fitting
for attachment of the hose going from the heatercore to the block has rusted
off and now what is left of the fitting is still in the block.
Does anyone know if this is a pressed or threaded connection and how do you
get it out.
