What did you do to your NBS GMT800 Tahoe/Yukon Today?

Changed the quick connect "Y" piece, its brand new and has a pinhole leak... WTF!!! LOLView attachment 251265


Gave the Denali a wash, then drove to a gravel parking lot for a picture... not very smart. LolView attachment 251264 View attachment 251263

Looks good. Is that y a Dorman part?

Yes it is, are they common for that? After a while it clogged up and stopped leaking.

Consensus about Dorman's parts is 50/50--with some parts being an absolute "NOT". Are you brave enough to leave it on since it stopped leaking? If it was me I'd change it. You know what'll happen--locally it'll be great, no overheating, no leaking, but as soon as you go on the highway on a trip the ***** will break! Causing you to get stranded. Me personally--I'd change it--while you can.

Like the truck, not the leaking “y” part!

Definitely will, i forgot to change the post it's not the "Y" it's the connector to it, which I also put new. Will change it, wonder of Oreillys will change it , since I just bout it this weekend. Either way it's coming off.

They should swap it out np.

Those Dormans Y's are known to fail fairly quickly and leave you screwed on the side of the road. They are bad enough that they have singlehandedly made replacing the Y fittings a topic of great debate and some people go to the extreme of putting in expensive metal Y's. The OEM ACdelco parts are known to last 150k + miles. I would replace them with the real deal so you don't need to worry again. The GM part numbers are 15055342, 15055343. Amazon or Ebay carries them. Or take your chances with the Dorman but you have been warned!

Got these 22” off a Sierra Denali recently. Truck looks wayyyyy better with these compared to the stock 17s.

Agreed. I hate chrome and those look good on there even to me.

This comment alone should say a lot about how nice it looks!
