I was prying the alternator back to get the top bolt in and all of a sudden it started leaking antifreeze from behind. What the heck are the metal tubes connected to the back? Are those carrying coolant?

 

my guess and this is an observation in your post, but yes... thaht would be coolant and those would be coolant lines.

 

Mr Clown spam...again

alternator...

 

I know I thought that was the funny part....

Clown: my advice would be to tighten up the muffler bearings they might be the cause to all your problems. Not sure of they are warranty or not, but check your local GM dealer. I think there was a tsb on them, but that can be found on the Yugo site.
