  1. I believe the wheels from 19+ will fit the K2, however the TPMS sensors use a different frequency so you will have to swap them or get new ones that work with the K2.
  2. Sounds like a vacuum pump failure. I’d recommend calling your dealer with the symptoms as I believe GM has a program covering these even beyond the warranty period. I’m sure others will be along to share specifics of that coverage program.
  3. Each sensor has a unique sensor ID. Your truck has a table that these sensor ID's are written into when you do the sensor learn procedure. If you removed the sensors from the vehicle (as they were pulled with the wheels), you will get a TPMS light after you drive enough. Having said that, if you put your old wheels and tires in the bed, your truck will go on reading them and not give any codes or lights. When you perform the TPMS learn procedure, what you are doing is telling the truck which sensor ID to write to memory that each wheel location (LF, RF, RR, LR) in that order.
  4. The dealer may be offering you a bit on the low side for your ‘17. One thing to remember is that you will not be paying tax on the trade in value so if the dealer offers $50k for trade and your sales tax rate is 7%, that would be $3500. If you were to do a private party sale, that’s how much more you’d have to sell it for to break even.
  5. It’s not a T1, but the magnetic ride on my 2018 Denali is impressive. It’s the best riding truck I’ve ever driven.
  6. Search for this "Fernco PQC-102 2" Qwik Cap". Its what I used. You don't need the clamp that comes with it. This works very well.
  7. In the 2018, it’s not really a seat cooler as there is no cooling module in the system. Instead, it’s a ventilation fan so until your cabin temp comes down (from the A/C), all they are doing is pulling hot air through the seat. In terms of flow, they pull the air through the seat and blow it out the back and bottom. There are two fan motors per seat, one for the bottom and one for the back. I have actually been pretty impressed with how much difference the ventilation makes vs just having a standard leather seat.
  8. How difficult was it to get the old one off the valve cover, and did you end up breaking any of the plastic off that you struggled to find among the rockers?
  9. Can you give the part number for this? Also, can you confirm that you didn't need to modify the locking grooves prior to installing?
  10. You are correct to be cautious before ordering. If it were me, I’d make sure anything I ordered fit a 2018 as well before I ordered it since as you know, your 2019 LD is really the same truck as a 2018.
  11. On the 2018’s, there is no RPO code sticker anymore. They now use a barcode this is in the drivers door frame. You can scan it with a QR code reader and it will tell you a partial RPO options list. The best way to approach it though is to send your VIN to GM Customer Care and ask for the build sheet report OR do the same with your local dealer. They can pull it up on GM’s system and print it for you.
  12. It is a thermal barrier that is intended to reduce the stress due to thermal expansion on the joint between the condenser and the tank that is attached to the drivers side of the condenser. I would say the jury is still out as to how effective this is as a fix, but this is certainly the area where most people are having cracks that cause all of their refrigerant to leak out and then have no A/C.
  13. I haven’t looked at the K2 fuel tank pressure sensor setup, but I replaced the sensor on my GMT900 without removing the tank or the bed. I managed to lay under it and reach my arm around the tank and do it completely by feel. This may be an option for the K2 as well. On the GMT900, the fuel tank pressure sensor had no mounting hardware, it was just a grommet on the sensor that you press through the hole in the fuel tank header plate. All I had to do was unhook the electrical connector and pry the sensor out of the bushing.
  14. Have you considered a GM 1500 with the 2.7 Turbo. I don’t think that has AFM and many are liking that mill. I personally have not driven one.
  15. Gmt900 and k2xx both use 315 so your proposed swap is fine. It’s the new T1 that uses 433.
  16. I have a set of 17” to run in the winter and the 20” that came on the truck stock. I’m quite confident that the 17” gives a more compliant ride over small road imperfections (think cracks in pavement). Another benefit of the smaller wheel is that you really don’t have to worry at all about curbing the rim because the smaller wheels have enough tire sidewall that the tire takes the brunt of any contact.
  17. Sounds like you are switching between V4 and V8 modes. The TC unlocks for each transition between the two as I’ve noticed this on my truck too. Watch the Fuel Economy screen in your truck on your next drive. It should have an indicator for V4 and V8. I bet that moments after you see the “flare”, you’ll see a shift from V4 to V8 or vice versa.
  18. There is an option in the settings menu for the park assist sensors to be enabled with a trailer hitch. Do you have this turned on? It may help here, but I’m not sure as I haven’t done it myself.
  19. I see most are doing the cargo on with reverse using a diode, but why couldn’t this one just be done with a piece of wire (no diode)? I think it would then give you Cargo on with Reverse as well as reverse on with cargo. I don’t see where this would be a bad thing and would give more light around the rear of the truck when loading / unloading with the cargo switch too.
  20. For those who want to go back to stock for trade in, why couldn’t you just do this mod as suggested but remove the belt from the vac pump and leave the vac pump installed (cap the vac port as it’ll probably see crankcase pressure with the pump not being driven)? In this way, the vac pump will still have oil flow through it and it won’t be able to flow out the vac port. The pump won’t be turning so it won’t develop any vacuum or take any power from the crank. When you want to go back to stock, just put the belt back on and route the plumbing back to stock.
  21. I thought I read on here that GM extended the injector coverage on the K2xx GDI injectors. I’m sure if you do a search, you’ll find something about it.
  22. Could the reason for turning the fans on when the coolant temp doesn't come up be a fail safe for a failed in range coolant temp sensor? By turning the fans on, you prevent engine overheat in this scenario. Back in the days of a belt driven mechanical fan clutch, this wasn't needed as the fan clutch was reacting to the heat coming off the rad and they were designed to fail full on.
  23. My understanding is that VXDIAG (with it's GDS-2 and Tech2Win cloned software) is as close as you can get to the GM tooling and functionality without spending the big $$$ for the GM subscription. It is reported to do everything the dealer can do with the exception of access online service manual information and reflash modules. Remember, it's a Service Tool, not a custom tuner. It'll be great for some trims and certainly for diagnostics. It's not something you're going to use to change fueling tables, trans shift points, etc. Those are not functions that GM supports through it's dealers unless it's a full module reflash and that firmware calibration has been released by GM.

  24. Remember that the Tech2 does not support the K2xx platform. You'll need GDS-2 to support the K2 and T1 platforms. The VXDIAG includes a GDS-2 clone (hacked copy) with it and that's what makes it so powerful. So in summary, the VXDIAG is a hardware interface between PC and Vehicle. It also comes with pirated GM software (Tech2win and GDS-2) that makes it very useful for diagnostics. If you want to reflash a GM module, you'll use the VXDIAG hardware, but subscribe to GM Vehicle Programming Software for $40 for 2 years per VIN. I do not have the VXDIAG tool, but I do know someone who purchased one and he used to work at a GM dealer. He's only used Tech2win on the VXDIAG for older platforms, but his impression is that the interface is nearly identical to the GM Tech 2.
  25. 1SLOW1500, Are you saying that if a private owner purchases the VXDIAG interface and the subscription to GM Vehicle Programming Software from the Delco TDS website, that GM will actually pay the private owner when they reflash their vehicle if it’s part of a recall?
