Fail-Safe Thermostat

Could it be that I'm loosing my mind? I thought I read somewhere a while ago that someone made thermostats that failed open rather than closed. I've asked at all the automotive supply companies around here and no one even seems to know what I'm talking about. Do they exist ? where can I get one? Thanks , John

 

I think This is what you're talking about:

Those are really nothing new...

 

here in iowa arnold motors supply sells them. not really sold on them. i prefer the stainless super stats. if you cannot find a fail-safe and really want one let me know ap and i will get one for you.

 

Even Auto-Zone has them or can get them in a day. Nothing new, TR

 

I put one of those turds in my brothers late model car just before winter a couple years ago. It made it one month before it stuck open and he was bitching about no heat!

 

Better to fail "open" and have NO heat,.....than to failr "closed" and overheat ?

How about not fail at all! The damn thing didn't even have 200 miles on it!!

 

I have a hard time finding a regular type thermostat, those damned fail-open things aren't worth a plugged nickel. They stick open if you have a little bubble of air anywhere in the system after you install them. Never had one work more than a few days!

 

i get the stant heavy duty ones. their supposed to fail open

 

Ditto!! I never liked them myself as they tend to "fail" (lock open) quite frequently.
