"Ideal" is an automotive parts manufacturer that started in Bavaria. I believe most of their parts now are out of Shanghai though. http://www.ideal-automotive.com

Got the NAPA thermostat too. Will see if it lasts.

When i worked at the autoparts wearhouse we stocked "ideal" and "stant" both and i think O'Reillys carries "ideal" but you may want to check with you local parts shop to see what they have....."stant" works just as good i guess.

Do either of those safely fail to the "open" position or are they just plain old normal thermostats?

just plain old t-stats as far as i know.......never had one fail on me yet.....

My Roush runs around 75C (170 F) and pretty sure Roush said I had a 180 F thermostat. But when it is cold out (say 50 F), the water temp seems to run much lower, maybe 40C (104 F). Why wouldn't the thermostat stay closed until the temps got up to 180F? The water temp gauge goes right into intake manifold, so it is reading the engine water temp which really should be 180 F. The thermostat isn't broken if during the warmer weather it holds at 75C. Maybe there are some holes that shouldn't be there? I'm glad there are so many experts around! Ha!

If you have an electric guage they are not as accurate as a mechanical guage.....hook up a mech. guage and you'll see what i mean.....
the out side air plays a big part in how cool your engine will run.....
if its 40 degrees out side and you have a 160 t-stat then your coolant will
probably not get warm enough for your t-stat to "cycle" and thats why you have a bypass hose it will allow the coolent to circulate and bypass the t-stat....
if its 100 degrees out side and you have a 160 t-stat then you car is probably going to run hotter than the 160 t-stat because you cant pump enough cool coolent into the engine for the t-stat to "cycle the coolant"........
thats why a lot of race engines dont run a t-stat they use a washer to restrict the flow
and allow the air being forced through the rad. to act as the t-stat...the faster you go the cooler it runs....you slow down it gets hotter....
i hope this all makes sence its easier for me to explain it when i dont have to type it...
