Our local chevy dealer buys Adaptive One pads from Napa when they don't have any of there regular parts in stock. Basically the same pads as the silver/gold because it's likely the same people making them for both places. Food for thought.

I do remember seeing that on the GM page some time ago but didn't really pay attention and just kind of glossed over the info. I guess I need to pay more attention to details. The good thing is that all 3 levels of parts are backed by GM which is important.

This is great, learn something every day, and thank you @newdude for the detailed info. Each of you have been helpful and why I love these forums. I as well didn't realize the GM part hierarchy with OEM/Gold/Silver but makes sense when you think about it. 

 

Relating to NAPA, I also tend to shop there vs the other stores and have found their parts to be pretty reliable compared to the competition (Napa Gold filters, etc..). Other things like this I try to stick with OEM where I can but as we have seen that's not always easy.

Will the Gold brake pads last as long as OEM and stop the truck as well?

 

 

We use the golds all the time.  They work quite well.

12674639/15-51125 is the 207F thermostat.  19474058/15-51125G is the ACDelco Gold/Professional line and is also 207F.  12674634/15-11113 is the 194F thermostat.

 

ACDelco Gold/Professional line are not the OEM part/supplier typically, they are made by one of the major aftermarket suppliers. 

 

So lets pretend that Motorad is the supplier to GM for the OEM one and build 12674639 to GM OEM specs, the ACDelco Gold/Professional one is supplied by Stant and is built to spec but might use cheaper components or alternative materials, etc.  Same with brake pads.  The OEM ones are made from the OEM suppliers (TRW, Akebono, etc.) but the ACDelco Gold and Silver line are all made by what was the Affinia's Global Brake division which is now spun off to Frist Brands Group.  ACDelco Gold and Silver all all the same as Raybestos brakes.    

 

 

 

 

Hey sorry to revive this but I just got a replacement tstat from my local Chevy dealer and they provided a cardboard box with an ac Delco gold part number of 15-11125G but it has the GM genuine part number of 19474058 right above it on the same label on the box. On the housing, it has the GM number then the ACD gold number and “Made in China”. This is definitely not oem, right? Did they discontinue the oem part or something? I’m just confused why a dealer would be selling aftermarket parts I guess. My truck is a 2014 1500 5.3.

That is the latest and greatest OEM thermostat.  They dropped it from being the "Gold" version and replaced the 12674639 with it.  Comes in a Genuine GM OEM cardboard box too. 

 

Also, GM has stuff made in China all the time.  

 

Also also.  Back to my original bit on these.  Its one of the major manufacturers of thermostats that was supplying the original OEM one, as well as the current version.  Motorad, Stant, etc.  GM doesn't make their own thermostats and if they did, its been decades.  Many decades.

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need.webcrimsNY

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
