[V8] POP..Hiss..Smoke..Antifreeze Smell..SOS!!!

Now, how the &*%@# do I get down in there?  Looks like a long weekend
job.  If anyone has some "lessons learned", I'd sure appreciate them.
Does the dash have to come off?  If so, this may be a chance for me to
replace the dash lights.

Hopefully I'll get the green light to work on it this weekend or
next...I paritally severed my ring finger and am waiting for it to heal
up.  I will probably go ahead and I/R/R everything cooling-related while
I'm at it.  I've checked some old posts, and apparently 98-105 degrees C
on the highway is considered "running hot"......

Thanks again.  All advice is greatly appreciated.

Hmm.  Sounds like the nightmare I recently went through.  In my case it
was the heater core (as pointed out by Mr. Head) began to disintegrate,
lodging plastic pieces into the return hose nipple of the expansion tank
it) and leading to calcification of the radiator internals, reducing
radiator efficiency to nil and causing failure first of the heater valve
and finally the heater core.  If you're lucky, maybe it's just the
heater valve (but your passenger side smoke description makes that

Good luck and let us know what you find.
