6.0L Power Stroke Engine and DrivetrainDiscussion of the 6.0L Power Stroke diesel engine and drivetrain in the 2003-Up Super Duties and Excursions. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.0L Power Stroke engine.
Was in Death Valley last weekend. Temps were in the high 120s and were 120 degrees F at 7:30 at night. Truck, as seen below, ran perfectly with no overheating problems even though the air conditioner was on high all the time. The temp gauge did not even move.
Was not towing that weekend, but was carrying a couple hundred pounds of junk I usually carry around. Only mods on truck are EGT gauge, 4 inch exhaust and Mag-hytec diff cover, along with the 35 inch Toyo Mud Terrains.
My 05 is as trustworthy as my 01. Truck has 12,000 miles on it now. Ron

I was on 395 west of there last weekend also. Forecast was for 128 one day(don't remember which day). If I remember right the N. America high temp was 135 in Death Valley. I only go down there in the winter!
Towns on the CA side were setting records for most days in a row over 100.
It was only in the high 80s around te Mono Craters.

I tell ya, when these trucks run properly they simply rock.
About a month ago I went to the Hill Country (central TX) to visit some vineyards. After buying a few cases of some good stuff we decided to stop in Llano for some good BBQ. That meant leaving 4 cases of good wine in the hot truck.
Not to worry. Combine a 6.0L with an AIC and you have perfectly chilled wine.
A friend of mine asked, "Won't your truck overheat when you let it run like that!?" [Me] "Nah, not unless you set it on fire." [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

I don't know if the newer trucks are the same., But my 02 had "IDIOT GUAGES!"... They always stayed in the middle... Temp, Oil and Volts....When loaded and climbing a hill the Temp guage should rise slightly, when warmed up the oil pressure should fall at idle...However, on my 02 They did not move!!! [img]/ubbthreads/images/graemlins/shrug.gif[/img]
Yep. Stock guages are junk. [img]/ubbthreads/images/graemlins/vomit.gif[/img] [img]/ubbthreads/images/graemlins/vomit.gif[/img]

Ford and other manufacturers have added a dampening feature to all their gauges. This keeps them from moving very much. In the case of the temp gauge, you will notice that it rises to exactly the same place and stays there all the time. This is not a very useful gauge, but deceives the public into thinking exactly as you believe. I believe the purpose of this is to keep the public from complaining about a moving temperature gauge.
I installed a VDO coolant temp gauge that actually indicates the temp of the coolant. And let me tell you, that gauge moves a lot. It is not uncommon to see 220 to 240 degrees under hot and heavy load conditions.
The manufacturers have done many a disservice by installing this kind of a gauge. I think it would be better and far more useful to install a functional temp gauge and add an explanation in the ownwers manual on how to read to a functional temp gauge.

You said it george!!!They won't do it tho cause it makes sense.Plus think how cheap that gauge is for ford to purchase.Anything that inaccurate has got to be cheap.
Forget the gauge. The truck ran in 120-130 degree heat and did not overheat - period.
Also, my 05 temp gauge has moved slightly when towing a heavy load. I believe too much is being made of this temp gauge issue. Believe me you will know when your truck is overheating - it will lose some power and eventually puke coolant from pressure cap or overflow.
My truck ran in these temps 2 complete days perfectly - never skipped a beat once in the 2 days. Never puked a drop and EGTs in very safe range even when climbing extended grades in those temps.

Ford Temp guages aren't that bad. They won't tell you if it's going up or down a few degrees, but they tell you if you're too hot and tell you when you're warmed up. That's what's important.
On the other hand, the oil pressure guage on Fords is just an on off switch. If you have enough pressure, it shows in the normal range. If you don't, it says low. If the truck is running fine, a stock guage is enough. If you're having problems though, it's an easy insurance policy.
EGT - that's another story...

The problem is that the vast majority of owners are not TDS participants, not even really enthusiasts, and just want a transportation appliance. And if the temp gauge moves, or goes to a number they don't like (nevermind that it's a perfectly okay number), they'll bring in a perfectly fine truck with no real problems to be checked out for overheating. Which drives up warranty costs. Which are passed on to everyone who buys a new vehicle.
For the folks here, who are enthusiasts, yeah, it would be better to have a proper gauge. But we, tragically, are a very small minority of the total customer base. And catering to us would cost the OEMs far more than they'd make off us. Luckily, the aftermarket has what we need.

On my 95 Impala SS I did a mod to the temp gauge as it was an idiot gauge also. There was a resistor in line that when removed allowed the gauge to read real time. Any chance of it being that easy on these trucks?

If you are to the point of losing power, damage has already occurred. [img]/ubbthreads/images/graemlins/vomit.gif[/img] The whole point of an accurate temperature gauge is so the operator can take a “pro-active approach” [img]/ubbthreads/images/graemlins/warmsmile.gif[/img] and take the appropriate action.

Hun. By the time my gauge went hot, both heads were blown, puked out all the coolant, and permanent damage was done. I bet FMC is glad they saved $20 on a real temperature gauge, and spent $ 9,300 repairing the truck.

I am surprised someone else (more knowledgeable) has not jumped in. My understanding is that the gauges are not defective or necessarily cheap. They are computer outputs, telling you what Ford thinks you need to know, and therefore not telling the whole story.
I, for one, would like to know when temperatures and such are gradually rising so I can take proactive measures.
I have the X-Monitor. I have seen my Trans temp read "normal" when the actual temperature input to the computer has moved from 100 - 170 degrees. I have not added a water temp gauge yet. But, I will.
The oil Pressure gauge is nothing more than an idiot light. If you have more than something like 7 lbs pressure it reads normal. Ford would be more honest if they just put in idiot lights instead of selling idiot lights that look like gauges.
