Thermostat temp
Hi All,
Just curious to see what temp thermostat everone runs now that winter is coming, I have a 170 degree in my truck and it seems to never heat up.
Should I go hotter? What does everone else run? What temp would have come in the truck when it was new?
351M, C6, Stock.
Thanks!

I just flushed my cooling system and swapped my thermostat to a 195 to get me ready for another cold New England winter. 195 should keep me nice and toasty.

I would NEVER run any cooler than a 180* thermostat in a FORD engine.
They were designed to run HOT 195*<
Ford engines do not run economically with cooler than 180*
>
>Should I go hotter?
Yes, Minimum 180*
What does everone else run?
Summer 180*
Winter 195*
What temp would have come in the truck when it was new?
195*

For most of its life, FE engines were specified with two thermostats, winter 180* and summer 160*. It wasn’t until almost the '70s when they started jacking up the operating temperatures for emissions. Later engine families were designed with higher running temperatures in mind.
>Ford engines do not run economically with cooler than 180*
True, but they make the most power there, at least according to my timeslips.

I run a 180* year round. I think this lets the heads run a tad cooler, and may extend engine life a little. I wouldn't go below 180*, though.

Thermostat temp
I just bought a 180 last night and while looking in the book, I noticed some of the fine print at the bottom. It said to only use a 195 if the cap was at least 7 psi? It didn't make much sense to me. My 195 I have in now runs the temp gauge at 215 so I'm going to swap and see if there's any difference.

Thermostat temp
205 degrees all year round. One has to remember your engine is a heat pump. The more heat you take away from the engine and throw at the radiator, the less there is to push the pistons up and down. I would never even consider colder than 180*. The coeffiecent of friction between the engine pieces rises as it gets colder and goes down with increasing temps. If I thought the coolant could stand it I would run hotter still, but 205 was the hottest stat I could find. DF
