Now that the barn find is back on the road (it passed inspection this week)
I have some cooling questions.

 

Firstly.  It has been running for the last couple of weeks just on water.
No point wasting anti-freeze and making a sticky mess if it leaks like a
sieve.  So far my only obvious leak is at the top of the radiator (see
question 2).  What is the recommendation for a modern anti-freeze type to
use in it?

 

Second.  There is a small pressure leak in the weld at the very top corner
of where the expansion neck is attached to the main body of what appears to
be the original radiator.  The running temperature on short drives (less
than 10 miles) looks good, so I would prefer not to overhaul/re-core the
radiator at this time.  Any tips on what type of weld this is and whether
they can be successfully rewelded/brazed?
