AHHHHH, well there you go. That is why I was hesistant to change out the T-stat two years ago when I flushed the cooling system and why I didn't change it this time either.
I know it's old (original), but the car only has 45K on it and it's working perfectly so I figured I'd just stick with it.
THanks for the feedback!
