Thermostat O ring?
I'm repairing the thermostat assembly in my 90, 5.8 bronco. The old thermostat is a 195 Fahrenheit model, and seems to be in working order (did the boiling test). I've got a new housing, and after some careful sanding and dremeling, I've got it in acceptable shape.
Now I'm ready to put it back together. However, I'm working with a buddy who thinks that there should be a o ring between the thermostat and the thermostat inlet to keep the thermostat from rattling around in the aprox 1/64 inch deadspace between t-stat housing and t-stat inlet.
I, in my devil-may-care fashion, am of the opinion to use some permatex thermostat silicone to hold the thermostat onto the t-stat housing during installation, which, IMHO, should reduce the wiggle room to a minimum.
Anyway, tl:dr: does my thermostat need an o-ring?
