2023 Silverado 5.3 4x4 Random Hose Hanging Loose After Oil Cooler Line Replacement

So I took my truck to another dealership besides the one I bought it at to have them take a look at the leaking engine oil.

 

Took 15 minutes for them to confirm leaking engine oil cooler hoses and they replaced them.

 

They couldn't figure out why the other dealer needed to add dye to the engine oil and make me drive it around for 300 miles to make it leak more.  They said it was totally obvious.

 

So I just spent 2 hours cleaning up the undercarriage of the truck from the oil that was all over from the leaking and the repair and I came across this random hose.

 

It is down by the front diff and terminates up near the battery where it is electrical taped onto a wiring harness.

 

Does anyone know what it is?  I don't recall seeing it before.  

 

If it was something important I can't believe that the service technician wouldn't have hooked it back up.  Maybe I should just rip it off?

 

Took off the right front wheel well liner to keep an eye on the engine oil cooler lines to see if they start leaking ... even though they were originally leaking at the engine block adapter.

 

They also said something about a TSB for the adapter bolts being too long to get proper torque which made connection leak at gasket.  I couldnt find that TSB and they didnt mention it in the notes.

 

Check out pics.

 

I also created a complaint with the NHTSA on the leaking oil cooler lines just in case anyone else is experiencing them. 

 

I had less than 1000 miles on the vehicle before I noticed the leak.

That looks like your front diff. vent. It should be up higher next to your coolant reservoir. I would move it up and zip tie it. Or you could leave it. Typical lazy tech

Thanks for the info. 

 

It was the front diff vent hose that was disconnected. 

 

Not sure if that was intentional or accidental. 

 

Glad I saw it.  I put it back on.  

 

Is there supposed to be a hose clamp to stop it from coming off?

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
