running cold

always... 1989 F250 with 460 EFI.

happened a few days ago. the temp. gauge doesn't ever get out from the lower-than-operating-temperature range.

I think the T-stat failed in the open position and the coolant constantly circulates, keeping it cool.

What's the recommended temp. for a new T-stat? Who should the maker be? Ford OEM, or will aftermarket stuff work like Advance Auto parts?

I got an OEM T-stat from Ford. It is a MotorCraft and the temp. is 192F.

I will install it shortly and see what changes this makes.
