what temp does u'r stang run best at?

[riceater89-5.0]

what temp thermostat do u use? (please specify u'r engine too!) thanx a ton

 

[The Shape]

180* stock engine

180* therm. H/C/I. Some how i run at around 170* with stock cooling system minus the a/c. I think removing the condensor helped ALOT.

rice eater, it is really gonna depend on how YOUR car runs. some guys have components that are not up to par, and they run a 160 stat and see water temps of 220 in traffic. others run a 180 and dont see more than 190.

generally speaking, a 180 is safe - no matter how great your cooling system is, the 180 should work fine. you can run a 170 also (dont know that i would delve into a 160, though some guys do and love it).
do you need heat in the winter? that is something to consider.

good luck.

180 stat, usually run around 160 170 ish on the highway

 

[riceater89-5.0]

the guy before me im thinking had a 190 in it, it ran at about 200 all the time. im trying to go from one extreme to the other, to see which my car likes best. its feels a lot more peppy with the 160 in it, but it also smells like its running rich, im not to worried about heat, i have a truck to drive in the winter, (my car doesnt get along with snow......or rain.....or gravel!!!) thanx to all who replied, much appreciated

I run a 180 but the car never gets above 160 170 im surprised my camaro temp bounced alot but the mustang stays in the same area. Runs peppy when its cold out seems a bit off when its hot.

180 steady after warm-up
Edelbrock H2O pump
"High Flow" 180 stat from Jegs
Once it warms up...it doesn't move up or down
Highway, drive-through...180
Pretty much stock 5.0
PS It loves a little cool humidity...go figure!

180-185. Check my sig for everything I have.

 

[92BlackGT]

Runs right at the bottom of the 'A' in NORMAL on the stock gauge. Before I replaced the radiator, t-stat, hoses and flushed the system, it always ran at the 'O'. I blew my upper hose on the way down to Tucson, so that made me update my cooling system. Run's a lot stronger now.
Mine's a bolt-on engine.

195* It's what the computer, and engine was desgined to run at. Mine stay around 190-200* when I drive it dead at 195*

Wrong. The eec has nothing in it that says it needs to run at 195* or hotter. The transition from open loop to closed loop is TIME based NOT temperature based. Running the car hotter will get you cleaner emissions and a little better gas mileage possibly.

I prefer mine run around 180*, but it usually runs cooler. I have to swap out my stat since fall and winter are near.

 

[GoldenEye]

I have a 180 stat and never get above 180 to 190. As a matter of fact on the highway I run around 150-160 which I think might be too cool. I'll be going to a 195 stat soon and adding an aftermarket guage and new temp sending unit to make sure everything is good.

 

[Stump1000]

I dont think that was his question. The question says "what temp does your stang run best at"

 

[Stump1000]

I run a 180, my stock guage is way off though, The more electrical stuff i turn on the higher it gets. who knows

 

[myfirstii]

We just went over this today in my automotive class....A engine runs best at around 180 to 200. Any thing under 180 will cause excess engine wear and ****y gas mileage and less power.

Ready to get proved wrong? Dynoed my old combo with car warmed up 299hp/329tq, gave it a half hour cool down, 304hp/339tq. I made MORE power with it COOLER. Go to the track and make a few passes at 200*, then a few passes at like 150-170*, hmm I wonder whats gonna be faster Ask your "teacher" if he knows anything about open loop and closed loop

 

[HISSIN50]

you are both kinda right (whether the power part Firstii said is right is arguable - and GRN i see your point).

the power part not with-standing, you are talking about two different apples - how does the car run best and what is best for the motor. two different things. generally hotter (within reason) is better for emissions and economy (as long as oxides of N. dont get out of hand or are catalyzed).

the thing i worry about is the oil. if one is running 200* water temps, it is not unreasonable that oil temps are at ~250* - not where i want dino oil to be for very long.

i would not be flogging a 'hot' motor myself.

 

[Grn92LX]

You have to find the happy medium and I find about 180* is that medium. I have to change out my stat since the colder months are comming otherwise I doubt my cars gonna even hit 130* if that

 

[408stroker5.0]

I like to run my 408 (see Sig) at 175-180. Seem's to run it's best at those temps.
