This is just some quick info for people with the 1mzfe who are looking for a slightly cooler running thermostat for their cooling system...
The stock OEM thermostat temp is 180 degrees farenheit, or 82 degrees celcius.
Without resorting to the expensive TRD thermostat at 100+bucks a pop, and running at 160 degrees which can be a bit too cool, when it comes to cold winters, etc, several aftermarket companies make 170F / 77C thermostats for the 1mzfe (as well as the 5sfe, but I just don't know the part numbers for them), a good temperature for mildly modified cars who are looking to run just a bit cooler than stock.
Motor Rad - 281-170
Gates - 33867
Also, these are non fail-safe. I'm sure you can probably get them in fail-safe as well.
And I'm sure there's more out there. These should come to less than 20USD a piece and any local automotive store should be able to order them, such as NAPA.
