No doubt you are fine, those tabs melt when the engine melts down.   You probably had some boiling around the cylinders, but I don't think you caused any damage in a mile and a half.  Just fix it and run it!

Subject: Possible...Overheating

Hello,
Today I was out driving (about 2 miles) and my alternator froze up and the belt broke. 
I took off belt and did not think about the water-pump being run by the same belt, "other stuff on my mind" regardless I drove another 1.5 miles and then it hit me. Pulled over immediately and turned engine off. 
Engine temp was still not up to normal operating temp as I had just started driving and it is currently below freezing where I live.  The gauge was rising quickly before I shut it off in a safe location. Opened up engine compartment, I could hear water gurgling but nothing was spewing out anywhere and it had not hit a temp that caused the coolant to go from expansion tank to overflow tank. 
Here are my questions. 
1. Have I ruined the motor...I did not see any coolant leaks anywhere. 
2. What temperature do the GoWesty Melt tabs actually melt and where are they located. (Just had a new engine installed recently...) 3. If the heads fail, would they leak immediately? 

I will get alternator and belts replaced. 

4. Is there anything I should watch out for when I do start it up next? 
Thanks for any advice. 
Regards,
Bill
