does anyone know exactly how a thermostat opens and closes? is it gradual, like a dialation process, or is it wam bam thank you mam, type of open and close.

also, i went to a 180-189 thermostat, stock i think its 196 or something, so im only staying 17-7 degrees cooler, shouldnt i have gone to a 170-179? I just hear about going down to a 180.

would like a straight foward, detailed answer, i know theres some engineering mind out there that can explain to me how it works =)

I dont know the answer to that question.... But...

You could always boil a thermostat on the stove to see how it works.

That is how you test a thermostat.

The boiling point of water is 215 F. so that will be sufficient.

Also, to really make use of that thermostat, you'll need a tuner to change the temp at wich your low speed/high speed fan kicks in.

Otherwise you'll only notice a difference when you are crusin' on the HW or running the AC(which turns the fan on).

found this on about.com:

"The secret of the thermostat lies in the small cylinder located on the engine-side of the device. This cylinder is filled with a wax that begins to melt at perhaps 180 degrees F (different thermostats open at different temperatures, but 180 F/82 C is a common temperature). A rod connected to the valve presses into this wax. When the wax melts, it expands significantly and pushes the rod out of the cylinder, opening the valve"
