2019 sierra 1500 SLT with 70,****** miles..

Looks like Engine oil cooler lines are leaking real good.

 

Having a hard time finding a replacement. Is it easier to just cut the bad spot out and use a clamp?

Please see the pictures. Its for sure the engine oil cooler lines right? Hard to see how they're routed, wasn't sure if it was for trans.

The leaking oil definitely looks like engine oil though.

 

I DO NOT WANT TO TAKE IT TO A STEALERSHIP. PLEASE DON'T RECOMMEND. But thank you for any helpful insight.

FREE UNDERCOATING. lol

 

But seriously, i believe that there is a TSB for leaking oil cooler lines, the dealership will replace this for free if your vehicle falls under the TSB, I don't remember the TSB number. Someone else can chime in or you can do the search. 

 

Are you still under warranty? Go to the parts counter and they can get you the correct PN to replace it.

Thanks. My search has only led to finding the GMC TSB N192220080, which says for Canada and Alaska. Called the dealership but they have to call me back...I absolutely hate dealerships.  Especially anything service related.

What help is it for you to respond on your doubts? Not even sure why people like you waste peoples time to add a comment that is getting us nowhere. Do you have insight on changing an oil cooler line? Do you know a TSB number? Like dude, blown away you came here to comment that you doubt a dealer will replace it. What help is that to anyone?

Found the Service Bulletin, it is attached. It reads as any effected 2019 1500(Chevy or GMC) will get the service completed, so long as its done by July 31, 2023. This should be free of charge. Still waiting on dealer to call back, but this is good info for anyone who is affected. The service bulletin is very detailed but I don't see any reason I wouldn't be qualified to get the repair done.

It's nice gm will reimburse for customer out off pocket expenses they incurred having the lines replaced. But they will never see this bulletin to submit a  claim.

I had mine replaced about two months ago. Would have cost me $1400 but, because I bought an extended warranty for the first time, I paid zero. For the record, I have a 19 with just shy of 97,000 miles on it. The leak started around 90,000 miles.

Thanks for having the service bulletin on here. Mine blew off yesterday and dumped oil everywhere. Towed to dealership calling them in the morning.  Have 53K on my 2019.

Looking at the carfax on mine (before i got it) it was replaced on my truck as well around 29k miles.

 

Seems to be a common problem.  Thanks for posting the TSB.  those are super helpful when speaking to idiot service advisors who don't know ****** about ******.  Very helpful for us owners!

Well, even though the service bulletin seems specific enough, it only applies to certain trucks. GM customer care recommended that I create a case once I bring it to the dealership. The dealership can then state if the problem seems to be the same as what is in the bulletin. At that point, GM may or may not reimburse.

TSB does not  = free fix, unless truck is under warranty.  TSB = Technical Service Bulletin.  Customer may present with "X", here's what GM has found to be the fix.  The phrase "TSB" gets thrown around like "Magnuson Moss" does.  

 

A special coverage or special policy would provide a repair in or out of normal warranty but your VIN must be applicable to it.  Dealer checks the VIN in GMs system.

 

Oil cooler lines leak all the time on these 2019-up trucks with the V8s.  

 

N212326940 that you found might be your only ground to stand on to see if your truck might be covered.  They'd have to run your VIN and see if that coverage is attached to it.  If its not, GM might provide some sort of assistance.

Oil lines have been leaking on GM trucks for decades, whether they are for a remote cooler or for remote oil filter lines like my 89 s10 baja had or my 95 s10 zr2. They don't fix them for free like i tried to tell the OP before he posted back calling me a troll essentially!

That tsb probably only indicates a batch made between this date and that date and at that specific plant. The lines are junk, they have always been a problem with GM either leaking or blowing out all together. I have never seen them out of warranty fix them free of charge, it was and has always been treated like a wear and tear item from my experiences.

Alright, as sort of expected, the dealership wants quite a bit to do the job and the part is, "back ordered with no ETA." The part the dealership gave me is 86788215. Looks like all the online sites have it, but I am not sure if I want to order it and DIY the job. I've only found one other who has done this job, with a 2019 Silverado. He removed front bumper to gain enough access.


At this point, I am considering trading in and being done with the truck..

      2021 suburban RST - acting up/lights flickering

      By 520Zilla · Posted

      Hi all,   I just bought a 2021 suburban RST with 88,000 miles on it and everything has been good but I’ve been noticing within the last month or so that there are small electrical things going on and I know what the AGM batteries and all the electric electrical in these big trucks you need to have a constant flow with good voltage   That being said, I bought a new battery thinking that that might have something to do with it but today I went to get in and start it and it said no key found when I had the key right in my pocket   It also proceeded to flash the lights inside and outside for over 30 minutes as I went to disconnect the battery as soon as I touch the negative terminal, I heard the relay reset and everything come back up. I got in the truck and started it no problem.   Anyone else have this happen to them? I’m starting to think it’s the KARR system that the dealer installed short circuit stuff.

      “Service Emission System” & “175 miles until “65 MPH Max Speed”

      By ManyCamaroz · Posted

      I don't drive this truck on a regular basis since I have a new company truck with no out of pocket fuel or maintenance cost. Yesterday I got it out to run some errands and got the title message on my DCI. A quick Google search suggested to first clean the Map Sensor. I pulled it out and it was sooty so cleaned it up and reinstalled it. Issue not resolved. My OBDII is a couple years old so didn't see any codes. Today I took it to a friend at AutoZone to get him to check it with his reader. It had the following codes: P20C3 P02BB P221F Stating the most likely solution is to replace diesel emission fluid (DEF) tank assembly.   So, I guess a trip to the dealer is necessary. I read where there was a backorder on these tank assemblies several years ago so hope that has been resolved.

      Do you keep your tires at full capacity? 80psi

      By Chuck FB · Posted

      Are you using a weight distribution hitch system with your trailer as that alone can change the actual tire pressure requirements needed. It would prove interesting to see what the actual individual axle weights are on your truck when you are hooked up to the trailer. In fact when your hooked to the trailer, typically if anything unless it has a large capacity weight distribution system that is over cranked, often the weight on the front axle will be less when hooked up vs driving empty and certainly if one doesn't have a weight distribution hitch. Really the only times one may get up there with weight on the steer axle is if there was a snow plow mounted on the front or a motorcycle on a rack or with a very large jockey tank full of fuel at the front of the box that transfers a bit of its weight to the front axle.    And of course your tires carry more weight for a given tire pressure due to their size vs a stock sized tire so there is that to take into the equation as well.

      Great info here thank you. I just joined, we have a 2014 Silverado truck we bought about 4 years ago with less than 5,000 miles on it. It has approximately 24,000 on it now. It appears to have all the standard issues that people are talking about. Occasional charging problems especially using 110 volt, occasional blinking triangle where nothing will turn on when first starting the truck but it will reset itself if you wait 10 to 15 minutes. Noisy coupler between the flywheel and the generator. Our truck is speed limited to 74 mph, is there any way to change that? The latest issue we have been dealing with is when driving long distance on the highway at full speed the generator does not keep the batteries charged. The meter will go into the yellow/red border Zone for charge status and the yellow triangle will illuminate solid but the generator will not keep the battery charged, not sure why the controller doesn't tell the gas engine to increase RPM to increase generator output it usually stays well below 25 kilowatts even though the battery is discharging and I have to slow down the highway to 45 mph and eventually pull over and let the truck idle to charge the battery so I can continue driving at speed. Has anyone had this issue before or have any idea how to diagnosed it? When via Motors was around it they were very helpful at troubleshooting. This becomes much if the Terrain is hilly and you're towing a small trailer

      Tonneau cover that does not leak water

      By Z45 · Posted

      I have the GMC accessory (REV) cover installed by dealer. Ordered with the truck.  They did a very good install job, can't find a single issue. Some water gets in around the tailgate but no where else.  You can see daylight around the tailgate but that's not the covers fault.  Installation is means everything. Guys at my dealer were seasoned pros, not inexperienced here today good tomorrow types, like many dealers employ for these jobs.   I don't mind paying for a professional job.
