[V8] new radiator

[Kneale Brownson]

Since archives searching is so lame, here's Cobram's description including using the cooler lines for draining.  He says the cooler lines won't drain the sump.  If you can't get the drain plug off, maybe one of those extractors with its tube run down the filler tube into the pan would do that part of the job.  Your best fill is to use the filler tube.  You don't want to be reinstalling those cooler lines when they're full of oil.

I got my new radiator last night - and it is an exact OEM replacement.
Same manufacturer, same look, same everything.
It cost about $100
more than the modine (as reported by other listers) unit, but it fit right
in. Sounds like it is well worth the extra money for proper form and
function.

My current problem is transmission oil. I lost some,
and want to change it all out with the OEM stuff - which I have. Problem
is, the drain plug is covered by a dirt deflector plate on the
transmission - which can not be removed without first removing the
crossover pipe - which is a PITA that I just went through. I am wondering
if I can suck it out through the cooler lines, and also put the new oil
back in by forcing it in the return line? Anyone know which is which? I
assume the oil pump suction line is the bottom of the cooler - right?
