Came out of Osoyoos BC in 32C weather pulling 4 place full of furniture etc.Trucks Temp gauge would show hot if I got into the throttle.Had to Set back to stock helped quite abit.This is pretty normal I guess??I mean I wasnt holding it to the floor or nuthin I was being careful.These hills seem like they are quite a few miles long with hair pin switchbacks.I was running a SCt programmer.

Was it puking coolant or did the gauge just get hot?

Was the fan engaging?

Is your heat exchanger stack full of grass/dirt/bugs/small woodland creatures?

It's tough to diagnose without more info.

Fan would engage, everything is clean.Coolant wasnt leaking seen a little that had come out of bottle but level was still good.

With an OEM tune, it's a hell of a lot easier to diagnose a problem than with a chip/tuner that mucks with the fuel/timing so much you can't tell what's going on at any given moment.

Of course, with the switchbacks, you were running big load at fairly low speed with an open torque converter much of the time, and that's going to make heat regardless.

Factory temp gauge still maxes out while commander shows about 204-210F.Getting pretty frusterating.Could it be a faulty gauge?

The problem with the factory gauge is that it basically has preset points. Once it gets to a certain temp it jumps to a certain point. You can see this pretty bad on a cold start if you sit there and watch it warm up.

that is probably what is happening. We are showing you coolant temp in real time and when the temp hits a preset value it is jumping the factory gauge way up. 204 should not do it but, I think 210 will.

 

[fullthrottle800]

At what temp will the coolant boil over then.Should I just ignore that factory gauge altogether?Cause Im thinking if it over heats that easy mabye ford wasnt the way to go.

I don't think it is technically overheating until the ECT exceeds 240F. I wouldn't think 210 would cause the factory temp gauge to spike to hot. Some of the '05 trucks had a faulty cluster that would read hot when, in fact, the truck was still within normal temps. I wonder if there is any chance your 06 somehow has a defective gauge?
