operating temperature

My Tahoe runs normally at 210...pulling or not. So did the 2007 Tahoe.

190 to 240 is normal. Does the gauge move?

Your cooling system thermostat does not open until coolant reaches 192-196 Deg F. Its OK. Boiling temperature of WATER is 212 Deg F and pressurized cooling system increases this temperature even more.

Not if it's a Ford.... They don't move for sh** until it's too late..

That's the only thing I hate about Fords.. Their gauges suck as far as telling you what is actually happening..

Even on my 13 F150, the actual gauges don't move once they reach operating temp.. They are just there to give you a false sense of security that "all is good"... Since the needles don't move...

I'm sure they will move, once you are overheating... But, what good is that?

Anyway, at least my 13 has an actual trans temp mode on the display, so I can monitor that... I've seen it go to 230 on the display, but the actual "gauge" didn't waver a bit from when it's running 195 in the dead of winter..

I know why they do this.. But, for us folks that actually know how to look at a gauge and not panic when it moves....

Yup! 190 to ~240 is normal so it does not move. I have seen mine move and it was not too late. Just slow a bit and it goes back to normal.

Just a lot of disagreement on how hot is hot such as this old blog post:

Don, I will send you a complete kit to install a 230F audible alarm that will not fail. The alarm is a chime tone. Use electrical tape over the tiny speaker to throttle the volume. The trigger mechanism has a service life of 10,000 actuations at full 27 amps. This circuit uses 20 milliamps when alarming.

I don't give a **** how "hot" people claim is "safe". The difference in the life of hoses and seals dumps on its butt at higher temperatures and increasing temp from say 200F to 230 does not improve emissions or fuel mileage. What is DOES do is NOT allow transmission fluid to cool as well.

I love the asterisks. It takes a mild four letter DAM and gets people to use their imagination to turn it mentally into SH** or even FU** Great foresight.

Sounds pretty neat, details on kit?

Thank you.

No the gauge is in the normal range--but I'm using a scangauge to display the temperature.
