Quality 180F Thermostat

Quality 180F Thermostat
Fits like it was made for it.
Stant Superstat - 45858 - $9.99 at Advance Auto
I crossed it from a Gates 33478S, so I expect that would work also.
It's a slightly off center design with a jiggle pin (to help bleeding the air out) in the flange.
Stainless steel, brass and copper.
Felpro 12994 gasket.
Edit: added gasket PN
From my testing it appears US thermostat temperatures are listed as the start to open temp and are fully open at as much as an additional 10 degrees, whereas the OE thermostat, 88c, is the temp when it's fully open. Nearly all auto parts stores list a 195, which is too hot.

I don't really know anything about those, but I don't get the point. Fully open is fully open, I would think.
If you're running a 180 and you overheat the thermostat is going to be fully open. Supposedly the MotoRad locks fully open if you overheat. Does that make it more fully open than any other 180 that's fully open?
I must be missing something.

When it fails.....
Actually, this one is not a fail-safe unit....MotoRad ETC4765 88C 192-200F. From reading around, it seems that this range is ideal...fully open at 200F. I got this one from my local parts dealer, so I might return it for the fail-safe unit.
After a recent head replacement on another car, I installed a MotoRad fail-safe thermostat. It worked for the first 50 miles, then failed sideways, meaning one side locked open. I replaced it using the same one and it hasn't failed yet, about 10k miles on it now.
At least it did its job and it got me home safe. If a normal one failed, it would have been on a tow truck.

Unlike standard thermostats, the Motorad Fail-SafeŽ thermostat, is built with an extra stroke that automatically locks into an open position when an overheating condition occurs.
MotoRad - Fail SafeŽ Thermostat
Google fail safe thermostats, aside from the motorad links, it's complaint after complaint about them.
Fully open at 200F is too hot. OE is fully open at 88C, or 190F.

IMHO I believe that practice in USA is stamp stat with start to open temp, while on the other side of the pond fully open temp is marked. So a 195F stat in US won't behave the same as one destined for the Euro market. The stats are not "snap action, they slowly open and close, you can toss one in a pan on the stove and simmer it. I live in a hot and humid climate, with slow traffic, so AC is always on and I run 180- 183 on the highway at 55, maybe a degree or two higher at 70. I got tired of seeing it go past 217, etc. I like my 180.
