How Hot??????
Ive got a 1990 Ford F250 7.3 ATS Turbo C6. 4x4.
Ok this truck never ever used to get hot. at all, or so i thought i pulled loads with it and it never got past the R on "NORMAL" well i moved to coalinga CA where it has been 100+ lateley. I saw the temp gauge always on R or M of "NORMAL" so i brought it home to find that it had NO THERMOSTAT, so i put a 192 from ford in it and have been driving it. Now after that here is the question. On a normal day of driving before the gauge would not ever move past the line after the C on the temp gauge. now when i drive the truck no matter the temp outside this gauge always sits on the N of "NORMAL" is this common, i get out and probe the water in the radiator and its at 180-185 just would like to know what you guys think.

I have always been a fan of mechanical gauges myself. I just went through the same type of issue and installed a Autometer water temp gauge and the temp is fairly consistent at 190 degrees. All of the talk about how the gauge is at the "O" in NORMAL always makes me laugh because that doesn't tell me anything about temperature. A real temp reading is what reassures me especially because I drive an old truck and I want to know what's really going on. I also run a mechanical oil pressure, exhaust temp, and boost gauge. If you want good info, get good "real" gauges.

I have three guages in my dash from Ford that actually indicate something that is really happening. They are the fuel, tachometer and speedometer.
A reading on the rest of them tells you one of two conditions is true. That condition is the key is on or off. The amp, oil and water temp readings mean nothing relative to anything that is happening.
The amp guage has never moved up or down in twenty years.
The oil guage always says something like M or A in normal when the engine is running. The mechanical guage I installed reads somwhere between 5 and 60 PSI depending on how fast the engine is running and how hot the engine is.
The temp guage always reads N and the mechanical guage is always between 185 and 195 depending on air temp and payload on the truck.
The volt guage I installed is much better than any amp guage I have ever seen.

Do not rely on your "idiot guages" (they are called that for a reason) install a mech guage so you know what is really happening. For what it is worth yesterday was 100 and on the way to Dallas the temp on the freeway was 190, in town got to 200. You can remove the sender in the drivers side head and install your mech guage in that hole.

Thank You
Thank you for your help, it turns out that my problem was a combination of many things, my fan clutch took a crap and the heater core kinda self destructed, and this motor didnt even have a thermostat in it. I will be installing some mechanical gauges soon. Thank you guys i really apreciate it.
