A few other thoughts you could bypass but keep the stock thermostatic switch open. You'd need to test to see if this would overcool.
Or keep switch open and use something like this to lower the open temperature to 180 degrees
I believe it closes at 165 degrees.
Also take a look at lower images on post #33
There is also a coolant loop that goes through the thermostatic switch to help speed warmups of the AT.
