i have only overheated once and that was because i forgot to plug the radiator fan back in and i've gone on a year with the car (and previous owner never changed it in the years he owned the car)
and thankfully the ECU goes into limp mode once it hits a certain temp so i didn't screw anything up
The plastic tanks don't handle overheating well. Form what I've read and researched they like to get brittle and crack. God Speed was the least expensive way to get into an all-aluminum radiator that I could find.
