Hi all!
Quick update - Blue Shirt came and helped me out, what an awesome guy! :clapper:

raise: :ty:
Fortunately it appears that no damage was done to the engine and she has since run smoothly.
I have taken her in for some TLC recently, spending a pretty penny on the cooling system and rear wheel bearings, but for now all seems to be in order once more.
For those who are interested, I had the radiator, expansion tank, expansion tank cap, and main pipes in and out of the radiator replaced, as well as the thermostat housing which was cracked. I didn't have the water pump inspected though...
Thank you all who responded with suggestions and offers to help. They are all greatly appreciated!
