New long block, high fan run times..

[TopherSho]

Ok, just to check with others, It's 70 outside, What is your coolant temp avg at on long stretches with steady gas at about 65-70 mph?

Should I put in a new 170 tstat?  Does the livernois/Torrie/eccopower tstats flow more?

Stock T-stat runs at 186 ish for me in 70 degree weather.  These cars are designed to run at a certain temp.  Ford designed them that way.  IMO there is zero need in any clime or place for a "colder" T-stat other then the factory t-stat.  It is a marketing gimmick...period.

#$%@ me,  i thought so.  im still running 215-230 degrees f ... where is this measured at?  maybe the sending unit/sensor is bad...

Hey AJP?  does your tune run the fans on a more aggressive curve ?   

[SHOdded]

Yuk!  Still a problem that has to be resolved by the dealer.  But wondering if there any air bubbles in the system, which you can try "burping" it for.  Also a thermal image of the radiator would reveal any hot/coldspots indicating radiator blockage.  Maybe incorrect spark plugs have been installed?  Might want to pull and check them (ALL of them).

sensor is on the back of the head above the trans, I have a flex not SHO so air flow to radiator is different (worse) and on a 75 degree day doing pulls for logs I was at 182degrees. I have a 160tstat.

my fans shut off as soon as car is turned off?

[TopherSho]

i will take a look at the sensor wire/plug  sigh ...

i am also going to put my non-meth tune back on if the strategy is the same as before.  it should be fine and will run the fans on BRAD's tune.  i just need to see the temp behavior under light loads with his old fan curve JUST to make sure .. but i expect high temps still

i really hate this cars utter complete unreliability ...

that is so weird, except my trans failure, I have full confidence in my car to drive anywhere.

So, here's a weird question, where else might the car be monitoring the temperature?.  Because right now even though it's reading high on temp the fans are behaving exactly as I remember they only spend up every now and then and only go to about 50% and then kick off...

So from observed interpretation it seems to be operating normally it's the gauge that showing me an anomaly

What is your SCT device saying?

CHT DEGF : 235

I will be perfectly happy if you call me an idiot and tell me I'm reading the wrong thing

Offs.. cylinder head temp.. my sct has the wrong guages showing...

Idiot is me   derrrrp

I have a solution....

Let's blame this on "Friday".

what was the actual gauge you were "mis-reading"?

*I* had the wrong gauges on display on the handheld .. looking at the data log now.  BUT i did have a bad tstat so the 1st time that the mechanic replaced after the car gauge went up to the hot line

[TopherSho]

168f max temp... now that im looking at the correct guage after the almost-overheat and replacing the tstat...  happy
