I have an '01 z-71 with the 5.3 motor. I messed up the head on my oil bolt and want to go to the auto store and get a new one. Any idea what size thread it is? I didn't strip the threads just the head of the bolt. I couldn't find the info. in my owner's manual.

 

Thanks

I dont know what thread size it is...but I was able to get a drain plug (not oil bolt...you say that and they'll start lookin at you funny) for my truck from NAPA. All I had to do was tell them make, model, year, and engine.

 

Not quite sure how you managed to mess up the head of the plug. What size socket are you using? Keep in mind that it is metric.

Ya its 15mm but the stupid thing says 1/2 on the bolt. Now who thought that up?

yep ...15mm is right....I think the 1/2 in on there because the theads are 1/2inch 14.

 

I think ??

to be 100% sure you should call the dealership and have them look up your vin# they will be the only way to be 100% sure.

:sigh::P

What??

No need to do that, all the engines use the same plug. Just go to any parts store, tell them your make & model and they can hook you up.

Go to the dealer and get a new one. If you get a universal oil drain plug, even if it fits, it may not be exactly the same and the sealing gasket may not seal properly. It is not worth trying to save a dollar in this case.

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Correct.  2019-2020 are serviced by a different p/n.  19420611.   The recall engines 2021-2024 are serviced with 12740076.     What the difference is between the two, I'm not sure, but 2019-2020 only show 19420611 as the replacement engine p/n.

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
