It's leaking everywhere! CAR WIZARD shows most common leaks on 2015 GMC Yukon

The 2015 GMC Yukon is a great SUV, but that doesn't make it perfect. The CAR WIZARD 🧙‍♂️ goes over what commonly goes wrong on this model, also the Chevy Suburban and the Cadillac Escalade.

I've repaired this before by cutting the metal tube before the rubber hose crimp. Using a flare to just slightly bubble out the end of the tube, then sipped a hose over that with a clamp and no problems since. But most shops will often elect to just replace the part with a complete new part because then you can be sure it won't fail, and if it does it's covered by a warranty.

I was in the Petro equipment business for years and we were using Pig Blankets. They make oil and gas only and another line for any liquid. Really handy. They also give away cool pig coffee cups.

Had mine changed while the engine was being swapped out. In the Acadia, Enclave series, these leaks cause other issues such as soaking the alternator in oil. Just a theory but, I believe heat exposure causes shrinkage in the rubber lines at the crimps.

Toyota had this same exact problem with their 3.5 V6 in the earlier years and Toyota redesigned the parts with 100% metal and they have no more oil leak problems.

Wizard, after you use the oil spill rags I recommend investing in some betonite Quick-Gel just a bag or two as it will last you a long time. It comes in a 80-100lb bag (about $7-$10) in a powdered form (think flour) and you can throw just a small amount and it will pull up the stains with minimal scrubbing with a push broom, this works on even old oil stains and after your done it can be disposed as trash. Best part is there are no chemicals it's 100% natural.

It costs money to use better gaskets and designs. They also make money on the parts, lots of money. Meanwhile, my '14 Accord with 213, 000 miles is bone dry everywhere.

I had some leaking hose assemblies like that a few years ago and I took them to my local parts store. They do a lot of hydraulic lines for farm and construction equipment and had the hose and crimp sleeves in stock, as well as the necessary crimp tools. It took just a few minutes to fix everything and I didn't have to wait for anything to be shipped. As I recall, it was a reasonable price too.

I heard Scotty Kilmer say on one of his videos that his dad used to tell him, "don't assume you have just one leak".

My 2015 Silverado with AFM delete is still going strong at 150, 000 miles so I agree with Wizard!

I have a 2011 Yukon XL 2500 with a 6.0L that has well over 220, 000 miles on it and It's dry as a bone everywhere! Zero leaks so far and it's an outstanding and reliable truck!

I had the same issue with the transmission cooler lines on my old 2000 Chevy Blazer. We had vehicle inspections where I lived when I had it so I had to replace them. We replaced them OEM AC Delco, but after less than a year the new ones also started leaking. It's a GM thing :)

Driving around in my 19 year old Lexus. Runs like new. That’s crazy!

[grampy]

When my trucks transmission lines started leaking i replaced it them with stainless steel braided lines. Even those will eventually leak but they wont break off and suddenly cause all you fluid to leak out miles from home. I like to fix things for the long run ; )

Thank you Wizard and Mrs. Ironic, I had the same problems with my '83 Chevy K20 130k, 5.7 fix one leak another started.

I'd be concerned about the direct injection, lifters and variable cam timing stuff causing $1000's in repairs in the next couple of years. A couple leaking lines isn't what I would worry about (they STILL need to be fixed though). GM isn't doing us any favors with a lot of their designs. What with the 3.6 V6 that needs engine out for timing chain, the 3.0 diesel that has an oil pump driven by a belt on the rear of the engine that means trans out to change at 100-150k miles (timing chain also on the rear.) It seems anything newer than 20 years old is a money pit of electronics/mechanical garbage. Ford/MOPAR/GM, doesn't seem to make any difference (or many foreign for that matter). Too much to buy the vehicle new. Too much complexity. Too much expense to fix. No wonder there are those companies advertising extended warranties, assuming they actually pay out.

2:00 I agree! I believe this is the sweet spot between modern and old school : )

[mwmceo]

Wish I had some respectable mechanics in my area that do things right the first time

[trentryan]

They could make lines that dont leak but why? Parts that last forever don't make them money, its all part of that planned obsolescence, you can either keep replacing everything as it fails or buy a new car which is what they really want

2015 and newer are not vortec fuel system engines anymore. They switched to the ecotec fuel system in this generation of gm trucks and large suv. The engines are basically similar but also different as well. I work for a GMC Buick dealership as a tech down in Georgia.

This is my favorite generation of the GM full sized suv. 2015-2020
