thanks for the fast reply, no ecm in my car,(too old lol) and, I'll check the others out in the morning when it gets light replaced the radiator today to and im done being a mechanic for the night! quick question, in your opinion would it be safe to drive the car even with the fan not working, about 12 miles to and from work tonight? and in the early morning?

Response From way2old

If it is a 91, it has an ecm

Quote "quick question, in your opinion would it be safe to drive the car even with the fan not working, about 12 miles to and from work tonight? and in the early morning? "

Maybe. If you have a temp gauge watch it like a hawk. Many cars will run ran with A/C request if not triggered properly by engine heat alone. If that works, just put temp setting to highest temp (up but A/C) and lowest fan for inside.

You said you were sick of playing mechanic but you could jumper fan directly with a FUSED wire to battery and alligator clip leads in a jam. 15amp fuse should do. Parts stores sell a length of wire that holds a spade fuse - handy to have for assorted things when made up as a jumper.

That's emergency makeshift trickery. If you don't know what and how DON'T! Loose wires must be out of harms way if you even think of something like that,

Need Help with low cooling temp sensor

Question From Needhelp62 on Need Help with low cooling temp sensor

I have a 1992 Buick Lesabre 3800, did a tune up on it. But i also replace a couple of sensor do to the code read out. I found the low cooling temp ,but no wires or harness to plug into.But i did find out if i unpluge the sensor on the backside of the engine in line with the fuel injectors , the radiator fans would run. But if you plug the sensor in it would stop runing. I still have no idea where the wire go ( yellow and black ) wires for the low cooling temp sensor with not harness. Need help PLEASE.
(edit out personal info)

SORRY FOR NOT PROOFREADING BEFORE I POSTED IT.

There is a Low Speed cooling Ing Fan Reday and a High Speed Fan Ing. Reday


The one i was told to replace was the senson that sits under the Intake Air on the drivers of the engine. The ECT sensor.

Sorry again and i hope this helps Thank you

Response From Tom Greenleaf

Not sure how you got in this jam, how you read codes with what conclusion?


Black/yellow is real common for a CTS, = Coolant Temp Sensor which is telling the "computer" how cold the engine is so it can deliver the correct amount of fuel based parts on that into. Pretty sure if unplugged you would flood it out.


Real common - the sensor is near thermostat and wiring from car should plug into new one if replaced or new ones can come with a new pig-tail of plug w wires to splice it in.


What code told you this circuit even was noticed by # please post it. That doesn't mean sensors are bad just that the circuit has an issue at the age sometimes the plug so new ones come with them as said.


More info needed. What troubles or why did you do this stuff to begin with?


T

Response From Needhelp62

I bought the car that way, i did not know about it being unplug. There are no wires to splice into. The serson sits on the drive side of the engine under Intake Air, right by the thermstat. I was told it was the ECT sensor and the codes were #15 and #23

Response From Tom Greenleaf

No wires or a dangling plug for this but the sensor must be there or it would have to be plugged as it touches engine coolant.


Various acronyms can be used - the key you said was black and yellow wires - where are those now?


Replacement should look like this now...........
/


Note pig-tail and shape of the plug. In this both wires are black and would usually just match up the location with the old one.


This if you don't see that shape on a plug somewhere or the matching part at the sensor I don't think you can make this run well with it missing, damaged or inoperational. Codes IMO don't mean squat yet if wires all messed up, pinched - who knows what you'll get.


If this is totally altered on purpose for who knows what reason I'm a bit lost to help. Probably if hacked up enough would find even a fixable used whole harness if that bad.


These and many cars have temp sensors for just telling engine controls how warm or cold engine is (this one) another for you dash gauge or light and another for when fan(s) should kick on.


If this was a bit newer vehicle it would be sending temp info for more than just those mentioned. If a bird's nest now this will be a challenge,

Response From Discretesignals Top Rated Answer

No such thing as a low cooling temp sensor. You sure you don't mean the engine coolant temperature sensor?

What is the code number your getting?

Yellow and black wires are the colors for the wires that go the engine coolant temperature sensor.

You should also proof read what your typing, so we don't need a secret decoder ring to figure out what your typing.

1992 Buick Skylark 3.3L Fuel Mixture Too Rich, HELP!

Showing 2 out of 6 Posts | Show 4 Hidden Posts
Question From axightly on 1992 Buick Skylark 3.3L Fuel Mixture Too Rich, HELP!

Problem: Vehicle is running too rich. 115,000
*No more that 11 mpg on a full tank.
*Black smoke is coming from the exhaust.
*Engine will not reach normal operating temperature(according the the temp. gauge, hoses and radiator and hot to the touch, system has pressure, hose going to engine does not seem to have fluid).
*Heat will work.
*Fan will not kick on.
*After a few minutes the vehicle will idle rough(sometimes the rpm's will jump up and down between 500-1100 while at idle).
*The oil level rises. Gas seems to be mixing with the oil.

I have replaced the air filter, spark plugs and wires. I have used seafoam and lucas fuel system treatment. The car will start up right away and drives great. What is wrong?

Response From Hammer Time

You apparently have a number of different issues that will have to be tackled individually. I would start out with the temperature, probably changing the thermostat. After that I would check the fuel pressure and see if it holds rest pressure when shut off to see if you may have an injector leaking. Change that oil before you do anything though.

Response From axightly Top Rated Answer

Thanks for the quick reply
What do you think about the coolant temperature sensor being bad?
I want to check the fuel pressure but auto zone wants a 250$ deposit for the gauge.

Response From Hammer Time

Your going to need a scanner to determine that. I would change the thermostat anyway. It's the only way you know it's good.

Response From axightly

could i take it out and stick it in a pot of water 200 deg. and see if it opens up. Is this a good way to test the thermostat?

Response From Hammer Time

Why bother? It costs $10. It should get a new one at regular intervals anyway.

1997 buick lesabre 3.8 surges

Question From jstockburger on 1997 buick lesabre 3.8 surges

Im having a problem with what feels like surges in my lasabre. When i drive at highway speeds and the engine is warmed up it tends to feel like my engine is surging. It seems like a very common problem with these cars, but I cant find a definite answer to fix it. I took it in to a couple shops and they all said its hard to pinpoint it because the check engine light isn't on. (they all told me different possible solutions from spark plugs to oxygen sensor to fuel pump to engine coolant temperature sensor and so on.

here are some examples of the almost exact same problem Ive been having:



please help :(


Links deleted. We don't advertise other forums Please post the specifics on your problem here.

Response From Sidom Top Rated Answer

While having a SES light on can help point you in the right direction, it's not a must to check out a car. If you can get the car to act up on a fairly regular basis at consistant set of parameters (speed, load , etc) you should be able to track down the problem. Now if the car won't "do it" when its at the shop, it get way harder, not impossible but in a lot of cases, it would be cheaper for you to bring it back when it's failing regularly...

One thing you can do, if there are some maintentance things you haven't done, now would be a good time to do them (it's something that needs to be done regardless of how the car is running) Plugs, wires, fuel filter, overdue maintenance items that could cause the probem you are having...........

Car overheating or bad Temp Gauge?

Showing 2 out of 8 Posts | Show 6 Hidden Posts
Question From BDRTFM on Car overheating or bad Temp Gauge?

I recently got an 02 Buick Century from a relative who is also a backyard mechanic. He was able to drive the car 100 miles or so without heating issues when he drove it out of town and back. However, when I turn the key, even before turning the engine over, early in the morning when the temp outside is pretty cool, the temp gauge immediately jumps to half way which indicates normal running temp - before I even start the car. Within minutes of starting the car, before I go more than a few blocks, the gauge is in the red and then the temp warning light comes on. I don't know if it's just my imagination but, it seems I can smell something as if the car is getting hot. But, like I said, that may be just because I am expecting to sense something that should be there if the car is overheating. So I parked the car and left it and told my relative about it. He came over, looked at the temp gauge needle without the car running, saw it climb a bit and said that there is either a short in the sending unit or a bad unit and he disconnected the gauge completely. I assumed there was something causing the car to overheat but, he said it looked like their was plenty of coolant when he checked it a week ago and that he didn't think there was a stuck thermostat so, it should be ok to drive for a few days without the temp being monitored.
I need to use the vehicle to get the kids to and from school and such but am afraid to drive it with no temp monitor at all. I still don't know if the car really is overheating or if it's an issue with the gauge. And it worries me that the fan won't kick in once the engine does start to get hot. So not sure if I should be driving the vehicle at all or what the actual problem could be. If anyone can give me an idea of what to do from here, it would be great.
Thanks.

Response From kev2

step 1 get the system scanned- its free at most part stores. Especially if the light is off.
then post all codes, also tell us which engine... someone will advise.


check coolant level before driving...

Response From BDRTFM

I'll try to get it scanned and post them but, the nearest place that can do a scan is a bit of a drive so, guess I have to hope I don't get stranded half way there or back. I have to grab the kids at school and not sure I trust even doing that. Really don't want to end up blowing a head gasket or worse. Not sure why he disconnected the sensor? I'd rather have an off reading with the temp warning light and fan coming on prematurely than have no reading at all.
Thanks.

Response From Discretesignals Top Rated Answer

When they scan it, it will have a coolant temperature sensor code stored because the sensor is unplugged. If he unplugged the sensor and the gauge is at zero, it isn't a short in the wiring. Probably something wrong with the sensor or there is some resistance on the ground side of the coolant sensor circuit.

You need that sensor operational not only for the gauge, but the PCM for fueling and fan operation.

Response From BDRTFM

So maybe the sensor itself is somehow creating a ground or resistance and causing the gauge to pickup an higher reading than the actual temp? I know when he unplugged it, the needle dropped to zero. And when plugged in, it never goes below half way. I was starting to wonder if maybe the stepper motor in the cluster was going bad but am not sure if each motor runs more than one gauge. So should I plug the sensor back in before the scan or will the code still be in there anyway?

Response From Tom Greenleaf

Tired at the moment - sorry. By unplugging this or things you are going to set codes no doubt that will remain for some time.
IDK - I find more troubles with connections and wiring for wrong info. In car you can test ohms thru the sensor at what exact temp known right where it's sensing. Some goofy to work with but infrared thermo pointed right at it should tell the actual temp and read on dash about that and sensor show the ohms thru it at given temps.
Plug it in and still get codes for some direction and check wires to it for anything wrong just because trying not to unplug stuff before a code reading,

Response From Tom Greenleaf

Arggh! Feel your frustration with no quick way to know if real or a problem that's real.
1. Do fans come on when reading is in or near the red zone?
1a. If not try this: Some even cold will force fans if not working properly to run with A/C or defrost request and would cool down even if you asked for the warmest request on the gauge if correct and no other issues.
2. A good clue with no tools it's overheating for real is if you know it's full of coolant - radiator included run heat full blast and feel air. If climate controlled that's not engine temp air but should be warm and pretty even for what you requested. If it goes cold it strongly suggests coolant is low or boiling as air thru a heater core doesn't transfer heated air well or much at all spells trouble is real.
3. If system can't hold pressure as felt (use a glove) at upper radiator hose you can feel it as it warms up from cold many vehicles do not cool or run fans over the boiling point of even the antifreeze mix so you are circulating air or bubbles - that's bad.
That can be just a pressure cap failed or a lot of reasons.
Some if cool ambient air and steadily moving along will be cool enough to be stable then rise when stopped or moving slowly like below 30-40ish MPH.
These just some things you can do to have some idea of real trouble or slight issue or find a problem with no tools, no codes nor accurate testing.
That only reduces odds if those things work not a fix nor assurance it can't really overheat.


There's a risk every time you drive that something will happen that strands you but can lower the odds.


Best you can do if you must drive it and hate to say stop if really overheating you'll be stranded anyway so don't make it worse,

Response From BDRTFM

Even with the sensor removed, the fan comes on almost immediately. As soon as I started the car when the sensor was plugged in, the needle immediately goes to the center even though the engine is cool an within 5 minutes or so, the fan comes on. And the heater is blowing warm air. I mean really warm air. I don't know if it's because my old cavalier didn't have a good heating system and just not used to it but the heat coming out of the vents in this car is very warm. I was feeling the line right where the thermostat goes into the engine and the line took quite awhile to get warm. It was pretty cool even after 15 minutes or so of idling. But it did eventually get warm. Not hot, just warm. And I haven't seen any coolant getting dumped into the reservoir either. But then, that's just while idling and revving the engine a bit in the driveway, not actually taking it for a ride. I'm tempted to just plug the sensor back in but, it won't really do much good because I still don't know if it's a bad sensor or something else like an air bubble or gelled up parts. I mean, until I see steam coming out of the cap or can fry an egg on the hood, I really can't tell if the warning light and needle going completely into the red are because of actual over heating or a bad sensor. I've never driven this car before so, I've no idea what is normal for it to make any judgement calls at all. I'll just have to risk driving to a place that can give me a code but, often those codes are pretty cryptic as well. Like my old cavalier that had a code saying their was a problem with holding a vacuum. That could have been any number of things. Turned out to be a almost invisible crack in the gas intake stem. But at least the code will give an idea where to start.
Thanks.
