In this video I have a look at a Buick Century 3.1 that came in with a customer complaint of overheating. Pretty common issue on these cars.... except in this case. Pretty sure the "computer" is lying to us. Let's find out!

Make sure you check the pressure control valve FIRST before replacing the transmission. I found out after a transmission replacement. It still felt like it was slipping. Solution was the faulty valve. Had to part ways with her as a noisy valve train revealed, a wiped exhaust lobe on the ol' bump stick and 2K to fix. I bailed out.

It looked to me like there was enough room for a deep socket and 3/8" extension.

Figures I didn't check it's function first, that's what I got for being in a hurry. I always enjoy your videos. Great explanations of operation and terrific troubleshooting techniques.

In answer to the question about using the secondary sensor as a backup: 1. The lower resistance of the green wire sensor will result in a higher temperature gauge reading but without knowing the resistance vs temperature curve it’s not obvious whether the reading would be disconcertingly high. 2. The orange/black wire is referenced to the internal circuit ground that the ECM uses to measure the sensor voltage. Since the green wire sensor uses the engine block as a reference, it might introduce electrical noise in the measured voltage since the block is also used for the alternator current return. It might be close, but it wouldn’t be exactly the same as the internal ECM reference and it wouldn’t be a clean signal. The result could be erroneous and fluctuating temperature readings. I knew a wise old electrical engineer that asked: “When is a ground not ground?” His answer: “Usually.” It would be interesting to measure the voltage between the reference wire and the engine block using a scope. I think you would be surprised at what it shows.

I think the point of the question was, if your sensor takes a dump, and the car is running like pooh because of it, and you are in the back woods of Kalamazoo, could you swap to the other half of the sensor, and have the car run reasonably well so that you could get back home with it. Even if there are a number of technical reasons why you shouldn't leave it that way, can you get home.

It should always be remembered that infrared thermometers can't be used on bare metal, especially when it is shiny because it reflects infrared light rather than emitting its own, AKA the emissivity is wrong, and also the spot size being measured grows the further away you are and will average the temp of everything in that spot so the closer you are or the larger the part being measured the better. IOW either measure the temp of the hoses or paint the metal flat black or use a flat black sticker on the metal and for something small like the hose you want the thermometer almost touching it.

@ouch1011 4 жыл бұрын

It looks like that sensor was, as you alluded to, designed to act as the sensor for the PCM and the gauge cluster. Older GMs that used this same engine (which may have still existed when this car was made) did not use class 2 data to run the gauges, they used connections to the engine, so it may have just been a matter of the engine being built as a complete package (including the harness) and having different body harnesses. Its easier to build one engines/trans package complete with harness than to build different setups for different cars

@kmath50 4 жыл бұрын

I had a similar situation with a Dodge Spirit 4 cyl. There was a head gasket leak, and the temp sensor was located where the exhaust was leaking into the cooling system. The gauge was reading hotter than what the engine was really running at.

Wow you were pretty thorough on this problem and it is much appreciated. It was turning into a can of worms and frustrating and I can relate to that. I sure wish you could have explored the green wire as a functional back up circuit , but you were losing money on this job and you got bills to pay so I don't blame you. I am having simulair problems with overheating so I am going to try this. Also I am told the radiator cap will not properly seat and (you can squeeze both upper and lower hoses and water gushes out when open) I have confirmed that. I was going to try and build up the seat/land of radiator cap neck with a two part epoxy . The new cap gets very oily and there is gunk in the water . A head gasket test was done and there was no leakage. I had the gaskets changed on the intake and valve covers twice over the last few years. I am going to look over your notes to see if you have that schematic . Thanks !

The dark green I believe is a carry over from the day when the gauge actually got it's signal from sensor and not class 2. I have replaced a few myself because the pcm would say all's well and the dash would be pegged. Instead of redesigning a whole new harness. The just reuse the existing harness.

@fascistpedant758 4 жыл бұрын

I don't think the temp senders for gauges operated in the same range of resistance as those. The green wire may have been used through another module like the BCM ?

@clinthelling3560 4 жыл бұрын

No it doesn't operate in the same range. It worked on 12 volt shorted to ground via the engine block. Like I said it's a carry over from the days before the IPC ever communicated With the ECM/PCM. That green wire was the same green wire used on a 60s or 70s Chevy. It wasn't until the late 90s to early 2000s GM even started using the class 2 data to report engine temp to the driver. My 77 C10 pickup used the same color code if memory serves me correct. I actually had a Chevy Malibu that used that post with the green wire to report to the IPC the old fashion way. Plugged in the scanner PCM said normal dash was reading hot. Replaced Sensor/Sending unit. Shipped it. Same as a unit to say report oil pressure and back up ground path form choke coil or fuel pump relay on injected engine. Some people don't realize GM only will produce 4 to 6 different wire harnesses for a whole line of chassis. Why reinvent the wheel so to speak. If the can reuse a harness they will do it to save cost.

I wonder if that temperature sensor is designed for a different engine and it was just cheaper to use the same connector and terminate the third wire at the main plug.

Kinda looks like a combined engine coolant sensor & temp gauge sender in the one unit ~ earlier models didn't use temp gauge derived from ECU?

Id bet it was for the different engines but used the same harness and sensors. They put 3.1,3.4 and 3.8 that were all basically the same block just bored differently

@@Sicktrickintuner ...just had a bit of a dig on this -- part suits over 450 different GM models --- post 2000 or so the part is referred to as 'coolant temp sensor' ...however... 1999 and before the same part is referred to as 'temperature gauge sensor' ...go figure =)

The 3 wire must be to ground a light in the dash for too hot

@@legros731 I don't think so, that's a different sort of sender ~ that typically uses a temperature set switch, not a thermistor..ie; reach 220F and close circuit to ground.

Eric I feel your pain every time you work on a GM product and wonder "why the heck did they design it that way?" I am a machine repairman for GM-Thermal Systems- Lockport, NY. The engineers that design the machinery to make the products are as clueless as the ones who cause you problems!! Can't work on these machines easily due to poor design. It's a GM thing!! Fight on Brother!! Love your channel!!

I definitely was that guy today watching your video sitting in my driveway trying to figure out what was wrong with my car. I have no automotive skills at all and thanks to this vid, I was able to find and replace the sensor on my own. Still cautious with it and I'll take it on a drive later but I just wanted to thank you for putting this video out, you're the best!

It "looked" like a chrome 3/4 socket, w/ wobble would have worked ?? Hard to see, from our angle of the dangle.... :)

I enjoy watching your inductive and deductive skills at work. I use a deep 19mm with UJ to access my temp sensor.

Typical gm recall on those engines for oil leaks and possible fire.

My car like that burned up a year ago! It had nothing to do with overheating! Oil leaks! Or sabotage! I had just put a DORMAN M.A.F. on it!! It blew up, after a cool night, before it even turned over for the first time that morning! Blew the plastic upper manifold off, lit the fuel lines, and melted everything that wasn't steel under the hood, in less than 4 minutes!! Even aluminum! I had little drips of copper wiring harness on the ground after I moved it! 205,000 miles, and not even a spark plug change in 7 years, and a new DORMAN MAF burned it down faster than a month old Christmas tree!!
