Themostat question

[eparks3211]

Has anybody considered or swapped out the focatory 190-215 deg themostat with a unit that will full open around the 190-200 deg range. If so could you throw me the part number info.

might i ask why? unless yours is running hot or you are pulling nonstop, its not in your best interest to lower the engine temperature. On a gas engine, it has a spark plug to fire the mixture. On a diesel engine it fires thru heat and compression, and when cooler then normal it will smoke, and not burn the fuel all the way.

Ask away. I pull a 13,00 pound trailer and it is not uncommon for my temps to hit 220-225. From what I have read 230 is the point you need to worry.
My thoughts are that the trucks run around all day at 190 under normal driving and the stock thermostat starts to open at 192 and is supposed to full open at 215. So I cant think of a reason that having a unit that will full open at 190 or 200 should hurt anything, but just the opposite.
It is also my understanding that the reason Ford installed the 190-215 unit was for smog purposes. The hotter the engine runs the less polutant they put out.

IN your case you may benefit by having a cooler thermostat, but with the load you are pulling, it probably wont help a whole lot....

Your thermostat is fully open, and your still hitting 225, all a cooler thermostat will do is allow it to stay cooler at the start of your run or pulling.

And around town, you will run alot cooler....

Yes i sure the thermostat is part of the bigger picture when it comes to emissions, but you cant deny the fact that, you need heat for a diesel to run properly, and most efficiently...

bumping it up for another try

I replaced my thermostat this past winter. It would never close, so the engine never warmed up. It ran like crap. I replaced it with one from Advance Auto. The information with the Thermostat said it was a 192 degree thermostat. It works fine in my 2004 F350 6.0L. Here's the info on the one I bought.

I would also like to know if there is an replacement thermostat that could fully open at 200 deg. My truck pulls a 40ft gooseneck everyday of its life. Why should the motor have to wait til 215 to get full radiator flow. Emissions BS if you ask me. With all the Diesel Sites out there, I'm surprised someone hasn't come up the the option yet, but I haven't been able to find it yet either.
