The seal was intact and unit was visibly fine, leads me to think it was stuck and just not opening and closing at the correct temps. On the truck I swapped in a stock replacement and it worked correctly.

I noticed it as I was doing some trans tuning and saw the coolant not going above 150 on a cold winter day. FYI the stat in our cars is 194 and the truck I believe was 210 or around there..was last winter. Temps Marked on the unit.
