"Stock V6 thermostat is 180 degrees. You do not want to install a 195 degree unit."
Just curious, & I'm sure you're right, but how do you know this? I haven't had my old one out yet, so I don't know what temp was stamped on the original - maybe you have? (Are Motorcraft stats stamped?)
The Ford Shop Manual (page 03-03-24) says that it starts to open at 183-190, & is fully open at 210. Haynes manual says starts to open at 189-194, fully open at 216.
The Motorcraft stat for this engine, #RT-1104, is listed as a 190.
So I'm confused....
