What is the Factory temp tstat on the 7mgte? Is it advisable to put a 180F in it? b/c i put a 180 with a hole drilled in the flange in my 3VZ and it LOVES it. Mind you i live in FL. it was in the 80's today! lol. So what are most of you guys running for tstats?
Best Tstat temp?

Stock is 195*. I run it in the winter to get more heater. Its in the 20's at nite here. I run a 180* in the summer, to allow the engine to run cooler if it can. I always cut that little toggle off it too. That way trapped air can escape to the radiator, and on out to the bottle.
That trick of cutting the overheat nugget and drilling the hole out slightly is a good one. I first used in on my 89 Vette with GREAT results. Ever since then I've done it on every engine. Seems to keep Tstat cycling down and temps more stable. Well here in FL last night I slept with the window open and just a sheet for covers. Unbelievable what kind of "winter" we have... really don't have. Still irritatingly Hot, I ran my a/c today in the house. So I think a 180 is called for.
Can someone post a pic of this thing to cut? I'll be installing a new tstat soon and would like to try this trick.
thanks guys,

You can't miss it. Its the loose dangly thing on the t-stat. Just snip it off with some sidecutters. Some people drill the little hole out to 4mm (3/16").
Just make sure you install the t-stat correctly, with the spring towards the engine, and the hole up top. AND....a NEW rubber t-stat seal.

If you have to pass a smog emissions test, you'd better use the 195 deg one, at least for the test.
