Thermostat questions

King Cobra 22 · Nov 29, 2005

My car runs on the cool side even in hot florida with the stock H/C/I.

I was wondering will my car run hotter with the new H/C/I?(TrickFlow kit)
If so I was thinking about getting a 180 thermostat.
I talked to a mechanic and he told me that running a 180 degree stat would waste more gas and would not be good for the motor.I could get problems like oil sludge yada yada yada.He told me engines run better when it's a little on the hotter side like a 220 degree stat.
Whats the truth here? I'm very confused.
And Will I waste more gas?

im in florida and i use a 180 with no problems

So this guy is recommending a stat that is 20-25*F hotter than stock. Your low speed fan would never shut off once the car reached temp.

No offense, but that is some horrible info.

You need to look at what temps your car runs at, not the stat rating. But a 180 allows the ECT to get into full fuel trim, and that is what matters IMHO. I also run a 180, as do most folks on here.

Good luck.

He was mostly talking about cars in general.

Like you said most people here run a 180 stat and when I brought up thermostats to this mechanic he told me my car would run better at a higher temp(not too high) basically recomending me to keep the stock stat which I believe is what something like a 200? Instead of getting a 180 stat.

Stock stats are 192 (our cars)

KC, I guess we should ask: where do you live (climate-wise)? And what engine-temps do you run at right now? And In the summertime? If you live in a cold climate, do you drive the car in the winter? (give folks a temp range that your car sees, and how well it does in those extremes).

In trying to figure out what the guy meant, here is where he may have been coming from:

I would use a stock stat if I had to drive in the cold winter.

The other thing he might have been thinking of was that many many folks think that if a little is good (a 180), more is better (a 160). This is not so, and if he was talkin about 160's, I agree with him.

So I guess more info about your personal set-up would help folks to figure this out and maybe help ya make a good decision.

Good luck.

Get a 180, make sure your fans come on (test with code reader) and be done with it!!

For my climate I live in Florida. I don't know the exat temp my car runs at but by going from the gauge It runs on the cool side of the gauge no matter what temp it is outside.Summer time is usually 90+ degrees and winter is usually in the 40's (coldest).

If my car is running cool maybe I wouldn't need a 180 stat?
Will I run hotter with new H/C/I?

HISSIN50 · Nov 30, 2005

The stat should regulate temps to its rating, so it does not really matter. As you can see, other guys in FL use the same stat (as do I, in the desert. Temps of 115*F to freezing and below).

Most important with the HCI is that you dont want to take a chance on running alum heads too hot. I would use a 180 on the HCI, even if in a milder climate. That is just me - others might vary.

Good luck.

HCI will generate more heat. A 180 stat, the fan coming on early (instead of 210), 60/40 mix (water/coolant) and a bottle of water wetter should easily knock 20 degrees off. To go even further then that I would suggest an aluminum radiator. My car runs at about 180 degrees all the time with all this in 90+ degree Florida weather.

Almost done, should be soon.

i run a 180 don't go any lower. something else that guy might be thinking about is the sensors. most sensors only start to be accurate once they reach a certain temp. Rick at AFM told me that the sensors for us don't work properly if they are too cool.
