So I was almost back to my house when I glanced down and saw my temperature display flashing at 225-226 F :panic:

I immediately shut the car off and quickly noticed that the hose the connects under the expansion tank had come off! (the expansion tank was recently replaced and I don't think the shop that replaced it did a very good job of securing the hose clamp back). I didn't have hose clamp pliers with me so I couldn't get the dang hose back on so I let the car cool down for about 30 minutes and then started it back up and quickly scooted home before it overheating again (I think when I pulled into my garage it was reading 197 or so). The engine sounded fine and it seemed to drive fine for the short distance I had to drive it.

Should I be concerned about engine damage or do you think I lucked out and turned the car off in time?

Sounds like you had plenty of notice and did the right thing and let it cool down. Your fine, don't sweat it.
Hopefully you are right! I guess I'll fine out soon enough when I can get a pair of hole clamp pliers and get the hose back on. I have a feeling I'm going to have to purge the system for a while too to get all those dang air bubbles out.

Got a pic of that hose? Im troubleshooting some intermittent cooling issues myself. Heat temps rise quicker than they used to from 184-200F where as a month ago it would only fluctuate from 184-190F at most even in traffic.

I have a whole log of testing that I did on my own (no special tools or anything, just idle tests & driving) if someones interested in seeing.

The hose I'm referring to is just the one that attaches underneath the expansion tank (number 11 on the diagram):



Also, as an update to this, I just went with one of the screwdriver-type hose clamps and used a small screwdriver that I had to tighten her up. Problem fixed! Honestly, I wish they would have rather went with the tightening type of hose clamps to begin with as they seem like they have a lot better seal...

Now comes the fun of trying to get all the dang air bled out of the lines. I let it idle for a good hour yesterday while slowly bleeding off air and then drove it around for a minute but there still seems to be a little air hiding somewhere. These coolant systems are a giant pain in the bum to get all of the air out of!
