Is this the one your meaning? It's the seal that wraps the outside edge of the thermostat flange. #3942454

speaking of thermostats in this thread i went to change mine this past weekend on my 12v and the bottom bolt is seized in the head. while trying to get it to budge i actually started to round off the head of the bolt. any tricks tha tyou all know? i have PB blaster sitting on it now hoping it will soak in, and i guess i will have to use my hot knife on the low setting to break the bond. I am just tired of being cold in my truck. j

I think that one's a thru hole around the back... you may want to hit the backside with PB blaster as well.
