Bad "New" parts frustration.

On my 5th t-stat from NAPA in one of our vehicles. And this one is no good...the store I deal with gives me some pretty steep discounts, and this is the only dead part that I have gotten form them so I will keep going back. Rich did mention a "premium" t-stat last time I got this one, perhaps it is time I try it...

There are even thermostats, that when they fail,, they "fail open" ,,

so you don't overheat your engine finding out the stat is shot..

you have to ask for it..
