overheating woes

I've had a couple.
But worse was when the coolant gelled in the rad one cold frosty Saturday night,while we were partying.
When it was time to go home,I went out ,set the automatic choke, cranked her up, and went back inside. A little while later, I noticed steam coming out from under the hood. Hyup she was boiling the coolant inside the engine and none was going thru the rad. So there I was pulling the rad out, at 30 below,coming out of my drunken stupor, with a huge pounding hangover, and three screaming babies inside who just wanted to go home.
It thawed out Ok no damage. A few hours later, or maybe it was in the morning, I can't recall exactly,lol, we were on the way home.
I hate cold-snaps,lol.
That same rad is in my 367 today.
That would be a ***** ! Talk about cold snaps, it 17 outside , only got up to freezing yesterday-----------
