What thermostat are Florida folks running?

Quick question for Florida boys and gals. Do you find 180 or 195 better in Florida?

180 All the way...

I only use 180 Hi-Flow Tri-bar Robertshaw Thermostats....and nothing else..

It really does not matter. If a 289 came with a 192* then that was the point the engineers felt was best to maintain minimum engine temp. Did not matter whether that car was shipped to Minnesota or Florida.


Once the thermostat opens, it is all up to ambient temperature, operating conditions and engine health as to what the temp the engine will be running with at any point in time. Removing the thermostat completely may seem like a good idea but it can cause the coolant to run too quickly and not spend as much time in the radiator for it to cool down.


If it is a sixty degree day in Florida in the winter, you don't want your engine to run at 180* when it should be running a minimum of 192*

Whats the difference between 180 in Aug and 192 in Dec?

The car doesnt know what month it is or what the outside temp is.

Granted the 192 will give you a bit more heat in the cabin than the 180.

Up north, big trucks block off the radiator when its cold to keep more heat in.

Nothing wrong with using a 180 thermostat and it’s my preference.
Idling in slow moving traffic on a hot August afternoon will cause your coolant temps to get above 200 no matter what temp the thermostat opens at.
I just like to give the cooling system a head start.

I used to run the 180 back in the 70's - 80's, but went to the 195 when I stuck the roller motor in 8-9 years ago.

And the proponents of NOT letting their cars come up to the correct operating temperature for maximum oil life, maximum performance, and best fuel mileage are at it again. And Oh Lord there's that letting coolant run too fast thing again.
Sigh. Somebody else take this one, I'm tired.

Is it really worth arguing about a 15F temperature difference?
No.
Its drivers preference in accordance with ambient temperature and driving conditions.
Does yours with a 195 thermostat perform better in a dry 100F SoCal summer environment?
I’m cool with that. Not gonna argue over it.
But in a 100F 90% humidity southeastern summer environment, mine performs better with a 180 thermostat. And it’s my preference.

Ford used both a "low temperature" and "high temperature" thermostat. If I lived in the desert southwest, the California desert or west Texas I might be tempted to use the "low temperature" version. Unless it regularly gets over 100*F daily I'd stick with the 195*F.

Ford engineering determined that the proper operating temp on the stock Mustangs at that time was for the thermostat to open at about 192* F. The window is high 190s low 200s. The optimum temp also impacts the oil temp. If you don't bring your car up optimum temp you stand a good chance of sludging the oil prematurely depending on how you drive among other things. What will happen is you aren't bringing your car to the optimum temp the engineers prescribed.

You 180 stat guys can argue and justify but there is no engineering reason to put a 180* thermostat in a stock classic Mustang. It's not going to prevent boil over. The misinformation comes from those that don't fully understand the mechanics and engineering of an automotive cooling system. They're going on a generalization of "cooler is better" without respect for the engineering parameters. A good example is saying a car performs better with a 180 stat. All it means it yours opens earlier.

To really measure it you'd need to do some dyno runs on the same day/time on the same dyno with the thermostats swapped in and out to compare. The "I feel it" seat of the pants dyno isn't able to tell. The way to tell is to test it. I doubt the guys claiming better performance have done any sort of testing it's just a mindset. For example out here I can hit 100 mph with 105* ambient temps and not come close to overheating with a stock cooling system. The stopping is a bit hair ball but the performance is there.

The guys that are hard core convinced the 180 is better come on back with some data and let us know how/why the Ford engineers at the time got it wrong. Remember to show your math...

So what if you make more power? Is 5 horsepower worth it? Even if you made an extra 10 horsepower by running 10 degrees lower - and I'm not saying that's the case - that extra ten or twelve degrees could be the difference between condensation and blowby boiling away, or staying in your oil.

With water in your oil, you get mayonnaise in your crankcase. You get rust. You get sludge.

And then you get a new engine much sooner than you want to.

Better to stick with the stock temp thermostat, and run in its intended temperature range.

“The guys that are hard core convinced the 180 is better come on back with some data and let us know how/why the Ford engineers at the time got it wrong.”

Not saying the ford engineers are wrong. I’m sure it’s exactly right for the conditions of their test parameters.
But would a engine designed for operation in Barrow Alaska work equally well in the Amazon basin?
Sometimes different conditions require adaptation.

What about an engine designed with a 172F thermostat? (Something I have real world experience with)
Would you say that the engineers got it wrong?
I would.
And so would those who operate those engines in below freezing temperatures.
(Hint: they never reach peak efficiency at low ambient temperatures)

I would certainly agree that a 160F thermostat far too low for a SBF.

It's like a science versus religion thing. If a person truly BELIEVES that a 180F thermostat is best then the proponents of the 192F are wasting their time with all their facts and evidence.

Random fun fact: Did you know it actually regularly gets hotter in upstate SC in the summer than it ever does in the city of Miami?

Lake City Florida is also regularly hotter than Miami.
What’s your point?
