bubbabubbs@yahoo.com - 04 Apr 2008 18:56 GMT I've been thinking about what my next commute car is going to be. 80 miles/day, it's just me and my briefcase, so thinking of a small vehicle with great gas mileage. Yaris hatchback, Scion xD, or Honda Fit would work for me. Problem is, none of them has a water temp gauge, just an "idiot light."
Would you consider buying a car (brand new) that only has the water temp "idiot light", but no water temp _gauge_ ?
Btw, do these "idiot lights" come on early enough to prevent major engine damage, or only after the engine has overheated to the point where the head gasket is blown?
Also, the next bigger models that do have the water temp gauge would be Toyota Corolla, Matrix, or Honda Civic. But the extra purchase/ ownership cost may not even offset the possible repair costs resulting from a Yaris/Fit/xD engine overheating (which, if happens, would be several years down the road.)
TIA, Bubba

My 5 speed 2000 Civic has/had/offered no tach not even as an option (thank goodness it DOES have a temp gauge) - it would have been such a pain to install an after market (tach) I learned to do without.
loewent - 08 Apr 2008 18:35 GMT FYI on your civic if you buy a used cluster (I got mine from Ebay) with a tach, it is a direct swap and the tach works without any further modification.
Kinda neat, frustrating at the same time.
And if you want to keep your original mileage on the odometer, just swap out the center gauge cluster. I bought a US cluster for my canadian car, so I didn't want to have to worry about converting from miles to kms.
It took me 10 minutes to do the swap.

Mike Walsh - 04 Apr 2008 19:35 GMT An idiot light might not come on soon enough to prevent engine damage. On some vehicles if you loose coolant pressure because of a leak the boiling temperature will be too low to cause the idiot light to come on. It is getting harder to find vehicles with gauges. Most cars I have owned had temperature, voltage, and oil pressure gauges. My Fusion has only a temperature gauge.

The coolant does not have to boil for the light to come on. The temp sensor only senses the temperature of the water, it has no way to determine if it is boiling or not. What may happen with a sudden leak is the coolant level will drop low enough that the temp sensor is no longer immersed in coolant. Being the sensor is no longer in contact with the coolant it will not turn the light on until it is too late.

But a true temperature gauge uses a sensor that MEASURES the temp,and the gauge gives warning BEFORE the temp goes "over the top". A gauge gives you more info,and sooner. A stuck thermostat may cause your engine tempo to cycle from 'cold' to 'hot'(affecting mileage) but an idiot light will not show that unless 'hot' exceeds the sensor limit.But a gauge will show that variation,and will show an engine running hotter than usual but within tolerance,showing something has changed[a problem!],that an idiot light will ignore. (until it's too late...)
Every car should have a temp gauge,not an idiot light.

If there is no pressure e.g. because of a loose cap the coolant can slowly boil away without the idiot light coming on. The same is true if you use only water with no antifreeze. The boiling point of water at sea level pressure is 212 degF. With 50% antifreeze and a high pressure radiator cap the boiling point will be about 270 degF. An idiot light might not come on until 240 degF. You are correct about the light not coming on if the coolant is low. I have seen engines that became so hot that the the head gasket blows and the driver swears that the idiot light never came on.

It's usually an "operator malfunction" for some folks not acting quick enough in response to a caution or warning light that is damaging. I've heard it said many times "I saw the light but I didn't know what it meant". I say to myself, hey, it's only money, why should you care.
If they didn't know what the light meant, I would doubt a gauge would be any more meaningful to them. Sometimes to learn what a light means, they see the results of driving with the low oil pressure light on in a sixty thousand dollar car because the person (woman) did not act, they just kept driving, until it stopped. Very instructional. Hubby was not happy. Like I say, it's only money.
You sound like an aware type of person, so a light instead of a gauge would be fine for you, but you could add an after market gauge if you wanted.

I've been driving a Corolla when I'm not in a truck since '03 and IMHO they are great cars, no problems.

None of them have oil pressure gauges either, or what a few years ago would have been considered normal instrumentation. You MAY be able to ask the dealer for a "gauge package" but the number of cars available with real gauges is slim.
>Would you consider buying a car (brand new) that only has the water >temp "idiot light", but no water temp _gauge_ ? I wouldn't. But what is even WORSE are the fake gauges which you see on an increasing number of cars. They look like real gauges, but they only register three different levels. Apparently having gauges that move around too much is "confusing" for the driver.
>Btw, do these "idiot lights" come on early enough to prevent major >engine damage, or only after the engine has overheated to the point >where the head gasket is blown? That depends. The basic idea is that they're supposed to come on well before the point of damage. But there's really only one way to find out.

You can always install aftermarket gauges. And not that although I wouldn't buy a car without gauges, I'm also a luddite who wouldn't buy most any car made today. --scott

But if it really bothers you, it's easy to get devices that plug into the OBD-II port and give you more information about your car than you ever want to know. For example:

Define "should". ALL cars are built on compromise. This particular compromise is very small, and shouldn't make someone not want the car.
That they made a decision not to include it, is immaterial. If you want the car, the $160 for a Scangauge may be easy enough to swallow to give you the car AND the feature that you want in it.

Yes. On many of the cars that have gauges now the gauge is nothing more than an idiot light with a needle. The gauge is either cold, normal or hot. Same with oil pressure... It's either 0 or normal. I was told manufacturers started doing this because people would bring a car back in for warranty repair when the gauge reading was still "normal" but not exactly like it always was.
>Btw, do these "idiot lights" come on early enough to prevent major >engine damage, or only after the engine has overheated to the point >where the head gasket is blown? They aren't as good as a gauge, but really who has cooling system problems anymore? The last time I had a car overheat it was because a hose blew out and in that case neither the gauge nor the idiot light detected it in time to avoid damage. Since neither was in water anymore they didn't detect the rising temp until waayyy to late.

I wouldn't upgrade just for that feature. Replace all the hoses every five years and don't worry about it.

truth is, water gauges are an historic anachronism. if you look at the typical car's temp gauge, they don't have a linear response, it's a step function. that means that when it's in the "normal" zone, there can be considerable temperature variation and you'll never see any difference in indicator position.
given that it's not really any interest when the coolant is cold, and there is no visible variability under normal operating conditions, that only leaves the "too hot" zone to be of any real interest - and there's no reason it can't be served by an indicator light. in fact, it may be a good deal more useful than a honda where if you don't happen to look down at the gauge to catch a problem in time, you can easily cook an engine. most people notice right away when a light comes on.

I've had many vehicles with real gauges and a few of them overheated and I never noticed the gauge go up because it happened so fast (blown hose). I might have noticed an idiot light. I'd like to have both in an ideal setup. It's nice to know what's happening with water temp on a long uphill, esp if you are towing something. My 99 Mustang GT has a temp, oil and volt gauge but all are just idiot gauges. At least on the mustang you can put the Dashboard odometer into "diagnostic mode" and it will give a true digital readout of water temp. I think most idiot lights for water temp are set to go on at about 235 degrees. If everything is good in the cooling system it should not boil till it hits 260 degrees.

Unfortunately if you want something like that you have to do it yourself.

With today's modern LCD dashes,such a thing ought to be easy to implement.Have a bright LED behind the hi segments that would light when those segments are activated.

Now that I think about it I think my Porsche works like that, but I've never seen the warning lights even bulb check. My fluke says everything is working fine, so I don't know what gives.

Even with a proper temperature gauge, you need to consider whether the gauge is in a visible place on the dashboard. First prize for "Most Stupid Position for Temperature Gauge" has to go to the Renault 14 (probably early 1980s vintage) which placed the gauge low-down on the central console, behind the gear lever. Not a place that you will frequently check it as you look at the everyday gauges like speedometer and fuel, and warning lights such as ignition, oil pressure and handbrake.
Many years ago my sister was driving my mother's Renault 14 shortly after she learned to drive and wrote off the engine because a radiator hose burst and the only warning that the engine was overheating was this insignificant gauge on an obscure part of the dashboard.

Under the hood, drill the dasboard, over the dashboard, place it on the left pillar. That's too time consuming.
Just get the "Scan Gauge" and plug it into the obdII diagnostics port. Besides it being a trip computer, one of the gauges is a water temperature digital readout. D.

OTOH,my 94 Integra GS-R had a stuck thermostat,and I noticed the temp gauge rising when I stopped and falling to 'Cold' when I was driving. I got the parts and fixed it before anything worse happened. And the last car I had with only an idiot light blew a rad hose (during a Buffalo blizzard) and left me stranded out in the middle of nowhere(Millersport Rd),except that a generous person stopped and gave me and my bud a ride ALL the why home,quite out of their way. The idiot light was useless to me.
Conclusion;idiot lights are for idiots.

while i "like" to have a gauge myself, engineering reality is that it doesn't mean much in this situation and an idiot light would probably be a better single choice if, like me, you just happen to be distracted and don't check the gauges and end up cooking the motor one day. a light is much more noticeable.

Just another sign of the "drivers are stupid, they don't need to know anything" mentality of modern cars. Well, not JUST modern cars- General Motors used nothing but idiot lights on most of its cars through the 60s and 70s, but GM was the exception. Then in the 80s, Ford started using "gauges" that were controlled by pressure switches for oil pressure- so that they either read "normal" or "zero". Yeah, real helpful, but it stopped people complaining about "the oil pressure changes when I speed up!"
From a driver information standpoint, the BEST setup is a gauge AND a "check gauges" light that turns on (and sometimes rings a chime) when a gauge is out of range. Its easy to overlook a gauge that's slowly creeping out of range.

Do you know the temperature inside your fridge? Oh, I see--you added a thermometer so you'd know. The little "1-6" dial isn't enough for you, so you added something the manufacturer didn't include. And yet you bought the fridge anyhow.

zzyzzx - 09 Apr 2008 17:27 GMT Then get a Ford Focus, or some other similiar car with a gauge instead. Then call up all the makers of the cars that you didn't buy and mention that a lack of temperature gauge was why you didn't buy their car.
I wouldn't buy a car without a temperature gauge, or tachometer either. That and I always add a voltmeter.

That and I always add a voltmeter. that makes no logical sense because the temperature gauge is extremely non-linear. it doesn't really tell you anything other than whether the motor is in the normal range or if it's too hot. and only one of those two pieces of information is actually important. a light can do that job, probably better because you might actually pay attention!
elmo's analogy is excellent because there's a lot of info about many things that any machine operator doesn't actually need to know - they only need to know if something is wrong. and this is one of those situations.

Oh, REALLY?
That's patently nonsense, and I can give you a concrete example. The whole point is that the gauge will tell you when some things are wrong that a dipshit light will not. My wife's car (1993 Chrysler LH) has an analog temperature gauge which, despite actually being routed second-hand through the engine computer, has come in very handy. That car has dual electric cooling fans, and a few years ago one fan motor failed. Because it had a GAUGE and not an idiot light, she was able to see that it was running just slightly hotter than normal (about 1/2 division, or maybe 15 degrees F) in traffic, so we opened the hood and checked things out. The one remaining fan *SOUNDED* normal, so I would have ever noticed the problem without that gauge, and my wife could have been stranded somewhere or I could have wound up with a pair of warped cylinder heads and a ruined engine if the second fan had failed also. Instead I was able to put the fan motor on order and then replace it without ever having to take the car out of service except for the actual time required to change the fan motor (about half an hour).
Similarly, I've had oil pressure gauges behaving in an abnormal way warn me that the oil filter had collapsed internally and was bypassing all the time- something that an idiot light would never do.
Lights are ONLY useful to call attention to a reading that's gone out of range. Gauges warn before the problem gets critical. The best of both worlds is a light that tells you to check the gauges.

The best of both > worlds is a light that tells you to check the gauges. <brag> My 2001 Trans Am has gauges. And a "check gauges" idiot light. And they appear to either be real gauges or very convincing software "clones" - oil pressure starts high at a cold start, varies with RPM and is lower at idle when the engine is warm. It even registers a bit higher when I run 10W30 in it vs 5W30. </brag>
Of course, it didn't come with a shift light.

When the nitrous kicks in, it's important that I don't hit the factory rev limiter.
(why? because the factory rev limiter works by dropping a cylinder, and if the nitrous is flowing and I don't get a spark, I'll probably end up blowing the engine sky high.)
And anyone who makes a comment about shift lights and automatics probably doesn't (a) bracket race or (b) have 400+ hp on tap. :)

********** It's good to know that my memory wasn't THAT bad! An upshift light is something that would have been pointed out in the New Car Features, and since I am not a fan of such lights, I thought I would have remembered it. The poster must have been thinking about his VW or something.

Yeah, my truck has the "hey dummy, upshift light you're going to get an extra .25 mpg" and my TA is getting the "hey dummy, upshift because the rev limiter's gonna kick in and you're gonna blow the motor" light. (It's after I replace the shredded factory clutch.)

The point is, something could go wrong at any time, refrigerator or car. Wouldn't you want a gauge showing you at a moment's notice as the refrigerant is slowly leaking out, so that you don't end up with a warm fridge and spoiled food?
of COURSE that's abnormal. But then, so is the car overheating.

The probability of a rock flying into the condesor coils underneath my fridge and causing a leak is astronomically low. The odds of a rock nicking a tube in my radiator is not nearly as low (lower if the car has A/C because the condensor would take the hit first....). Also there are about 4 to 9 pressurized rubber hoses and 8 to 18 hose clamps all waiting to leak on a car cooling system, not to mention fans that can fail, thermostats that get sticky, and radiator caps that quit holding pressure, etc. etc. And that's just the SUBTLE failures that will first show up by mild overheating, not the disasters like a burst hose or blown head gasket.

But the probability of your $900 fridge being a cheap piece of Chinese junk and leaking coolant and ruining the food in your fridge is MUCH greater today than it ever has been.
Hence, it would be prudent to protect your food investment, if nothing else, by using such a gauge.

Yes, the car is an appliance--for 99.9% of the people out there. Yet you, somehow, think that your desire to have a temp gauge that behaves the way you want it means that it's a necessity.

Actually, >>I<< never said that it would stop me from buying a car at all. Its trivial to add a gauge if its important to you (and it SHOULD be, but I digress again.) On the other hand, when I see that a manufacturer took the time to put in a gauge, it makes me think hjust a little more highly of the competence of the engineers who stood their ground against the air-headed right-brain type stylists, marketing lizards, and bean-counters.

Steve - 21 Apr 2008 21:46 GMT > no dude, it's the other way around. the engineers doctor the gauge so > it only tells you two things - normal and too hot, and only one of those > is important. That's simply not true. The HISTORY of the situation is that engineers installed gauges for years. Then came idiot lights because designers and stylists liked the "modern, all-electric" look of the dashboards they could create. Then gauges made a comeback. THEN, the automakers started getting complaints from people who'd grown up on idiot lights, and didn't understand normal behavior, most particularly of the oil pressure.
THAT is when the "dummy" gauges that read mid-scale or nothing at all appeared.
> left to their own devices, they'd leave the waste of > space out. Engineers NEVER leave instrumentation out of ANYTHING if left to their own devices. Left to their own devices they'd install an oil pressure gauge before the filter, one after, and one at the last feed off the oil galley. You'd have a water temp gauge before and after the radiator, a transmission oil temperature gauge before and after the cooler, and 8 individual exhaust gas temperature probes.

This would fail to solve the first engineering problem, which is have a good car of xyz dimensions. You can't get everything in without trading off something else that is important to the engineering. It's also false that engineers do not make economic decisions. In this instance, more gages = more manufacturing costs = less than optimal sales and profit.

I might have exaggerated a bit, but in general powertrain engineers would argue that electric seat warmers be omitted to meet weight and cost before they would leave out instrumentation. Certainly very few powertrain engineers would want to leave something so basic as a temperature gauge and oil pressure gauge out of their own car.
Elle - 22 Apr 2008 16:07 GMT > Elle wrote: >>> Engineers NEVER leave instrumentation out of ANYTHING if [quoted text clipped - 19 lines] > weight and cost before they would leave out > instrumentation. Me being a retired engineer specialized in power plants, it depends on the instrumentation. (Call that a nitpick; I am betting you know this.) A prime example is the tachometer. Many automatic transmission cars have one. It could be argued to be superfluous for auto trannies and manual trannies. I suppose it is in auto tranny cars because it helps sell the car, though.
> Certainly very few powertrain engineers would want to > leave something so basic as a temperature gauge and oil > pressure gauge out of their own car. I do not think anyone here disputes that some sort of gage or idiot light--one or the other, at least--for coolant temperature and oil pressure is a very good idea. We're talking about automotive design and how systems integrate (e.g. when it comes to using space; offering safety to the passengers; etc.). A contingent of engineers will be focused on passenger comfort, and with the marketing department, they will run the numbers and find that the seat warmers sell X amount of cars at Y price, so they need to make it work for Z dollars a car.
Related aside: Laypeople of course can discuss this topic intelligently, because this is about tradeoffs. Many of these tradeoffs are understandable simply with the application of common sense.

Not only that, but it is helpful, because one is able to determine what gear a car is in by comparing the vehicle speed with the engine speed. Plus, if one has a manual transmission, if the engine speeds seem to creep up when going uphill, but the road speed stays constant, this suggests that there is a problem with the clutch (and soon, your bank account is going to take a hit).

Actually, good engineering means reducing the number of gauges. Imagine if every operation on your computer required a gauge. You'd have one for your disk drives, ethernet card, wireless card, one for each of your USB drives, for the temperature, a bunch for different keyboard settings, for your floppy diskdrive (older machine only), your fire wire, for the state of the batteries, your video port, the audio I/O, etc.
Your computer would have more gauges than a nuclear power plant (and Bush wouldn't be able to say it, either).

There is some good info about how engines work on the internet (How stuff works has a lot). Plus, there is this neat building(s) in most towns called "a library" where they have books on the subject.
And if you're in school, you can ask your science teacher, too.

Right now I have a CPU utilization bar graph in the lower corner of my screen. I can switch it to network I/O, disk I/O, or disk space used if I want.
Good engineering really means making the RIGHT information available at the RIGHT time. With a car, the critical things that need to be displayed are fairly simple: Engine temperature, oil pressure, speed, and fuel remaining are the big 4. The best designs, as I have said, make all 4 available as analog readouts, and ALSO will turn on an attention-getting light and/or ring a chime if any of them (except speed) get out of the normal range. That's been done for decades (my wife's 1993 car being so equipped) so its just DUMB to regress.
The point I've been belaboring is that to reduce oil pressure and water temperature to ONLY a warning light is actually denying the driver information that he/she might occasionally want or need, and which can be valuable. Certainly the average driver doesn't need to know the exhaust gas temperature and oxygen content, but with only 4 basic readouts really NEEDED, why deny any one of them? It would be a different matter if there were 10 parameters equal in importance to oil pressure and coolant temp and designers would have to start making decisions about what needs to be primary and what could be secondary, but there just AREN'T!!

And even though its mostly window dressing, it does come in handy even in an automatic car to indicate if the transmission starts slipping, TC clutch fails to lock, etc. But yeah, 99.999% of the life of the car, a tach in an automatic is worthless and a prime example of something that's there ONLY for marketing.

A major component of my WHOLE ARGUMENT in this thread has been that DUMMY gauges are just idiot lights with pointers and are therefore as useless as an idiot light. How could you POSSIBLY have missed that, other than deliberately doing so just to pick an argument?

"The whole point is that the gauge will tell you when some things are wrong"
but now you're admitting that a warning light is as much use.

so you're contradicting yourself and arguing for nothing!
bottom line: if you want full instrumentation, install it yourself. the stuff you get with the car is good enough for the job it has to do. any /real/ engineer should know that.

Because /not/ wanting one is just stupid. Sure, there are reasons for el-cheapo line cars not to have a gauge, and that's fine. But for any driver to say "I'd rather have a light" is just flat dumb. No way around that.
What really gets me is the idiot gauge- costs MORE than a light, but is less useful (because it doesn't attract attention, and worse yet may even give the unwitting driver the impression that its a real gauge.
> quote: > "Gauges warn before the problem gets critical." [quoted text clipped - 3 lines] > > but now you're admitting that a warning light is as much use. Not at all. Gauges do warn you before things get critical, and you blatantly left out the obvious part of the second statement, which is that a gauge will tell you when some things are wrong WHICH A LIGHT WON'T TELL YOU. Hence my examples of 1) a dead electric fan which was indicated as a slightly abnormal gauge reading but which was not far enough out of range to have turned on a light, and 2) abnormal oil pressure behavior which indicated a collapsed filter causing the bypass valve to open, but was technically within the "normal" range and never turned on the idiot light.
> quote: > "gauges are just idiot lights with pointers" No, I never said that YOU read it that way, but its not what I said. I said that "idiot" gauges (the kind that are just controlled by a switch which either sets them to the normal range, or drops them to zero) are just idiot lights with pointers. I never said that real analog gauges, whether mechanical or electric, are idiot lights with pointers.

Without the operator knowing how the machine works in the first place, a gauge is absolutely useless.
See, your mind is in a very, very narrow place. YOU wanted to know how the thing works, so YOU found out. Others don't know, don't want to know, and in many cases can't understand it even if they try. A gauge is useless to those people.

No, not really. I remember in driver's ed, a few decades ago, the instructor explaining to us that every few minutes you should move your eyes over the instrument panel and look at the gauges and see that they are all more or less nominal. If anything is in the red, pull over and call for help. If you notice it moving toward the red, get ready to pull over and call for help.

You can lead a horse to water, (you can even shove it's head down in the water,) but you can't make it drink.

That's simple psychology.
Unless you know the principles of operation of the whole machine, the gauge will indicate nothing to you. It may be behaving perfectly normal within its own context, but if you don't know the context then you don't understand its behavior. If the needle wiggles around up and down, the guy who has no idea what the gauge is for will worry. Hence the "idiot light driven gauges".
And if all you end up with are "idiot light driven gauges," then just put in idiot lights. You save money, and you get a better alert.

And my grandparents and great-grandparents, some of whom never completed high school (and at least one grandmother CERTAINLY didn't "understand the operation of the whole machine") read analog temperature and oil pressure gauges perfectly well. Never melted down an engine, never took it in to the mechanic unnecessarily either. Are you telling me that driving-age people of 2008 are simply too stupid to do such a simple task?
