UPDATE:
The WATER PUMP quit today for my wife while on the highway. The heat gage was well PAST the dreaded RED line before she was able to safley exit the highway...and when she did, the car stalled. (It then started to smoke and leak antifreeze)
And hour and a half later when I got there, I could still feel the heat radiating from the thing. The coolant leak was just the overflow doing it's job...nothing bursted.
The water pump is shot.
I was able to start the car without a problem...BUT the heat gauge stayed WAY past the red line. (It's stuck)
SO, my NEW now question is. How likely is it now that the head gasket is going to go now too? Maybe it already has? I was able to drive it for 1 minute to a "safe spot" without a problem. Every thing seemed fine.
This can't be related to my vent problem...can it?
Should I post this in a new forum topic?
