I probably could have told you that months ago. one fair warning. pop that plastic plug quick otherwise youll get covered in oil. it drains FAST

thats the same location for the filter and plug as the silverado, including that cross member haha

It was a question that was asked at some point. I thought I heard they were changing aluminum in 2024.

Thanks for the warning on removing the oil plug. I am going to let the dealer do the first oil and filter change at 500 miles, so they can remove the factory installed filter. It seems like they are usually cranked on so tight, there's a risk of tearing up the metal can.

The only thing I see that sucks about this is you can't use a Fumoto valve. So I will either have to find a plastic compatible version, or a metal pan. I'm also fairly sure the last people I would want touching plastic on plastic parts like this is the low man on the totem pole doing oil changes at the dealer. I know a lot of places offer a "free" one for the first one (and most try to magically forget it, especially at Ford dealerships), so it can be enticing to take them up on that offer, but that's a big nope from me. At least you can get under it easy to inspect after IF you let them do it, like, before you get in it wherever they park it. Still a chance they will use an impact gun at put 4,000 ft/lbs on both the filter and plug.

Also, is there a crush washer or rubber of any kind on the fill plug? I assume it would be rubber and not just plastic on plastic.

I'll be getting that first FREE oil change in a week or two, and I'll see if I can get a photo of it.

I don’t really see any problem with the plastic oil pan. It’s probably tougher than cast aluminum, not many steel pans anymore.

keep in mind that these plastic pans do not need the plug reefed on there, it has a little click like feeling then its on. Ive delt with the fumoto valves at work before and honestly couldnt care less that its there versus a normal bolt. it does drain waaaaaaay slower though

Are the plugs or O-rings on the plugs considered reusable or replaceable item?

I guess I'll just have to experience it.

My jeep was the easiest I've had, high enough to slide under without a jack, oil drains nice right into the pan, no mess. Filter is a cartridge up top, again no mess.

It’s a mess, no such thing as a clean change on this motor…Expect to get covered in oil a few times until you learn a trick or two hahaha

all the tools you need is the filter wrench and a 3/8 6” extension and a ratchet.

I wonder if one of these tite-reach extensions would make the job easier?

Keep your hand out of the oil flow at least.

probably not, i really wouldn't waste the money on a gimmick like that.

with a normal ratchet and a the 6" extension you can angle it a bit to keep clear of it as you go. and you need that drop to help clear the frame and other stuff.. its hard for me to describe what i mean but think of a wobble extension angled off to a side, with that you can clear the mess, if a little. and do it enough times you should be able to change the oil relatively low mess hahaha

On the other hand, using a metal drain plug in a metal insert that's molded into a plastic oil pan is a recipe for someone going gorilla mode and cracking the pan due to over-torquing the plug.

It's not like they added this to a metal oil pan, and I expect the metal oil pan coming soon to the 2.7 will have a normal drain plug.

And aftermarket metal oil pans coming in 3...2...1...

Interesting! I wonder why they just didn't make the change for Model Year 2024.

Climbing under my Denali for the first time o look around and I have the metal oil pan. It's not a cast aluminum but it is metal. I didn't try to stick a magnet to it. But while I was under there, looking at how GM puts partID decals on almost everything, my passenger side brake backing plate had a decal with 05102023 on it. Date of manufacture it would seem to be. Delivery was on 6/6/23.

Has anyone done an oil change with a metal pan? I’m looking for the crush washer that goes along with it. I contacted a parts department and even for the metal one it gives them the rubber o ring even for the metal pan. The metal and plastic pans are calling for the same rubber o ring which doesn’t sound right to me.

Also GM uses the same part number interchangeably, so 12732388 brings up the plastic pan even though it’s the part number from the picture with the metal pan.

GM metal oil pan part number for the 2.7L is 1273-2388. 2.7L turbo, 2nd design. Replaces part number: 12728544.
Make sure to tell your GM parts guy you want the metal pan.
You will also need 10-2006 RTV.
This also moves the oil drain to the corner and has a threaded oil drain plug.
