Ok i was drivin my car today, and today was the first day that it was below freezing here.....and of course my radiator was frozen and didnt know it!! And the temp gets hot (all the way to the red) and me like a moron keeps driving it.....but only for like 3 mins. ANyway, if i did mess something up what would be the symptoms? I feel no power loss? And it still runs strong that i can tell. What should i look for if i messed something up?

 

One thing to look for is oil in your coolant....

 

Run it the next time its not frozen. I would do a leak down test and a compression test of the motor and make sure all the numbers are good, if they are you should be fine.

Also look for white smoke out the tail pipe, and check for mixing fluids in the crank case.
