Knowing the Helm FSMs, I am almost positive that it addresses removal of the thermostat, SOMEWHERE in the book. It is also a FSM. It usually does not list step-by-step the process for what usually requires basic mechanical skills.

Torque specs are either in the narrative or listed in a diagram somewhere at the begining of the section. It takes a bit of hunting in the picture, but they do list a torque spec for pretty much every nut and bolt in your vehicle.

Good Luck,
Michael
