Are you sure of that part number? It comes up as the same for the previous years...

No I have not. They (gm) did some "improvements" for the '24's. Maybe the 'improvements" weren't! Are you saying your Dad's dealer has 500 of them down, or gm customers, nationwide?

Nice, but what was the sticker price? Make sure to take your heart meds, before looking!

You could also have them look at Bulletin 22-NA-027 and see if your camshaft cover serial number falls into a bad design. See attached bulletin. You could inspect it yourself.

Welcome. Any chance you could use a different dealer? GMC, Chevy, Cadillac? It doesn't matter, they will all work on them.

They would be in front of the cooling stack. Sounds like you don't have them.

Were they closed?

Also, welcome!

These damn things. If the louvers are open you will see nice shiney bright aluminum fins of the radiator.

I sure would!

Look thru the grill, with hood closed.

I believe it a combination of things, temp and speed. But the ecm at the end of the day. There is a plastic motor mounted on the left radiator support, that opens and closes the louvers, sorry, shutters. If'n you have something like the launch, it has the ability to command them open and closed...

It's hard with a denali. AT4 ans SLT, no problem.

They are between the grill and radiator. They are black. They are plastic. They are a pain in the ass. They will malfunction.

Sorry, that's what I call them. gm calls it the Active Areo Shutter Technology. They are in the OM...

I have heard this before, but the guy lost his engine, towing. Dealer couldn't find the problem. I asked him if'n they looked at the damn louvers, to see if they opened. He responded back a few days later that was the issue and couldn't believe they didn't check them, being at the dealer...

Are the louvers opening?

Welcome. Post pics when you get it home!

Wow, that is low mileage on a turbo.

Yes. I felt the same way. Make sure you lube the o-ring good with fuel and use a six-sided socket. I bought 3 housings on Amazon from iJFJ for my trucks. No issues with them. I agree with the ease with filter replacement, but was more impressed with how easily it was to prime.
