temp

the factory guage isn't worth a shit. Get a good autometer gauge to really tell the temp of your coolant. The best thermostat to use is the factory Ford piece. 19X degrees. Can't remember the temp right off the top of my head. Hopefully, you did not use a 160...

I've had problems with parts store t-stats sticking open or running too cold (2x times in a row). I finally gave up and got one from the dealer and it works just fine. The cost wasn't that bad either.

Yeah, I can't explain it either.

the factory ford thermostat is a 192. I have an autometer mechanical guage in my car and it says that I run around 170, but the thing is that I have a 180 t-stat. The factory guages are terrible. they are basically an on/off guage. Something is wrong here!
