Damn... next you're going to tell me I should check the oil level
occasionally.... They put that friggin' dipstick in there and now everyone expects me to use it??? BLASPHEMY!!!! The engineers have told us that there are certain things that *should* be done to ensure that we extract the maximum troublefree miles from our cars. There are things that the engineers tell us we *shouldn't* do if we expect to get as many troublefree miles from our cars as we'd like....... Time and time again, accountants, computer wienies and university grads (would you like fries with that?) are consistent in their efforts to re-invent the wheel.... trying hard to vary from tried and true practice and, somewhere along the line, falling far short of their desires. Most premature catastrophic failures are the result of operator inattention or poor maintenance practice. The modern auto is one of the few places we can save money be spending it.... we just have to spend it soon enough.... "Anthony Giorgianni" > wrote in message ... > You sure, Fred?

If you are talking about explorers I have no data, but I know the late model mustangs have a phony voltmeter and oil pressure gauge, and a half phony water temp gauge. Neither show anything but dead center no mater what the actual reading once its higher then some very low trigger level. As the other poster said, the water temp is a real gauge till it hits 90C, then it stops moving even if the temp goes to 102C. That's the highest mines ever gone. Presumably it will spike up at some very high temp, my guess would be at around 120C. Even when cranking the starter the voltmeter stays rock steady at mid scale. >>Water temp - Not exactly.

If so, this is the first time I've ever heard of that. Our Explorer is a 92, hardly new. But the Expeditiuon is a 99, and the gauges are all real except the oil pressure. I have never seen any posts to any groups or newsletters saying the newer ones are different. -- Bill Funk Change "g" to "a" |

I think it depends on which models have the electronic dash. The Mustangs got it in 99 but I don't think the Exp did till later, if ever. The dash looks "analog" but it's really a digital dash driving analog gauges. My guess is it's cheaper to use gauges then digital readouts. You can put these digital dashs in "diagnostic" mode and then the trip odometer digital display shows the actual "gauge" values. Many of them appear to have a digital range of 0 to 255 which I believe is an 8 bit (or byte) digital resolution (I'm not stating it well). From what little I've read, the dash is even tied into the computer in such a way that it would be hard to swap a dash from one vehicle to the other without having the ford computer system to hook it too and reset it's parameters,i.e. a V6 dash into a V8 car, or an ABS dash into a non-ABS car. -- Elbridge Gerry, of Massachusetts: "What, sir, is the use of militia?

I pretty sure all the gaugues in my '03 Expedition are basically "go" / "no go" gauges and not true analog gauges. The temperature gauge does ramp up till it hits mid scale, but then it never moves. Likewise the oil and battery gauges seem glued in place once the truck is running. This is defeinitely a change from my '97 Expedition where only the oil pressure gauge was a 2 poition gauge. I think many of the people who get upset about the two position gauges don't realize how crappy the old electrical analog gauges were. I have a Dodge truck that came with an electrical analog oil pressure gauge. The damn thing scared the crap out of me all the time. I finally installed a aftermarket gauge (analog non-electrical) and discovered there was not a problem. The battery and water temperature gauges in my 1992 F150 move all over the place all the time. However, they are not calibrated, and as far as I can tell they are almost meaningless unless they go full scale one way or the other. A gauge that is not calibrated is no better than a go / no go gauge. By the way, as far as I can tell, the water temperature gauge in my 2003 Saturn is positioned by the PCM and is not actually displaying the actual water temperature. When you start the car it moves off "C" to the same place everytime and then slowly moves up to the exact same "normal" place everytime no matter what time of year or what you are actually doing.

By the way, as far as I can Perhaps if you only want to use the gauge to get the actual water temp, voltage, etc., that would be true. However, even a non-calibrated analog gauge is quite useful if you take note of its normal characteristics. When the gauge shows a change from how it usually behaves, that can be very helpful in alerting you that something has happened and should be investigated. These changes can be subtle and not severe enough to activate a go/no-go idiot light or one of the so-called 'idiot gauges' under discussion. My 1993 Aerostar has a non-calibrated temperature gauge and non-calibrated voltmeter (neither of which is an 'idiot gauge'). I have used both of these gauges to correctly diagnose the need to fix cooling system and charging system problems before they became hard failures. |

But I haven't seen anything about this even on the Expedition Digest. On my Expedition, the voltmeter and water temp gauges don't move much, but that's because the systems are working in good order. When idling at night, with lights on, the turn signals will cause the voltmeter to fluctuate, and the power windows do too. So I seriously doubt that's a go/no go gauge. As for water temp gauge, the Expedition has never had a coolling 'misadventure', so the needle stays put after warmup. -- Bill Funk Change "g" to "a" |

For sure the Voltmeter and Water Temperature gauges on my 1997 Expedition were true analog gauges that moved in response to changes in the system being monitored. But for my 2003, they don't seem to be. And for the 2003, the wiring diagram indicates they are driven by the PCM, so I am reasonably confident they are now good / bad indicators. Ed |
