Its coolant disguised as oil. TSB 20-NA-166 - 20-NA-166 1..3 "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix" I'd say its the head, and its either leaking at the casting line and dripping down the intake into the cylinder, or its another spot on the casting itself at the cylinder that is getting wet.

Yea that's pretty normal to be off a few degrees after sitting. Usually 2-4 degrees from say a weather app or thermometer. I've seen it a bit more if you are parked facing the sun too when its really hot out.

You SHOULD be. IF you underinflate, you can compromise the truck's handling and stopping. Its an 8400lbs truck. LOTS of weight on the front end empty. Ideally you'll want 55-60psi all the way around. Tire light. GM dealers won't help. LIABILITIES. Others have mentioned tools that exist. That will be your only route.

Open the driver's door jamb. What do the cold tire PSI ratings on the tire placard show? I'm not saying to run it to those numbers, but I would like to know what it says.

Nah. That's called tripping over dollars to pick up pennies. Bean Counters-R-General Motors.

The fact that they went down with the other fob tells me the windows down with remote feature is still on. I would double check those settings in case the other remote decides to start doing it. Should be under "locks and remote start" in the settings page.

Read THIS - UI-Bulletin_147b-Snow-Plow-power-provisions.pdf The one P/N in there you need for both plow install AND for upfitter switch install. Read THIS - UI Bulletin 153_wip.pdf Important question. Do you have KEYED ignition? Or is it PUSH BUTTON START?

See...I think they are worse aside from Habanero. They are all some sort of super dark color like a super dark red or blue or teal. And the new 2027 Silverado EV colors that are coming, same thing. Dark, dark and dark.

Yea I don't get the weak color palette at all for both brands. I count 9 colors on XLT trim Ford F150, 7 on Tremor and Raptor just as examples. The color options aren't all that much better or different however, but there is a bit more choice still.

What is the build number in the radio? Go to SETTINGS, then to SYSTEM, then ABOUT and find the BUILD NUMBER line. The newest is Y181, prior version would be Y177. If you don't have either of those, your radio is not fully up to date.

Ambient temp sensor is installed at the bottom of the grille shutter at the front of the truck behind the grille. That would not be the ambient air temp sensor. That would be the windshield outside moisture/ambient light and humidity sensor. Not the ambient temp sensor.

This can be done. It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness. The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right The problem with doing all of this? You pretty much can't have any programming done to your truck that involves the cluster ever again. The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with. So it would be advised also to turn off over the air updates. TLDR; Should have bought an LT double cab? You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.

Yes. The 2.7 Turbomax has Active Fuel Management. It is NOT the same as the V8s. Totally different system. Here is an article from GM when the 2.7 came out explaining the cylinder deactivation and the valve lift system. Starts at the section called "SCS Valvetrain": New Turbocharged 2.7L 4-Cylinder Engine Powers Full-Size Trucks – TechLink This is an internet myth going around. It was alleged that some 5.3s had this mystical 8th digit of the VIN as an "E" which somehow meant it had a new one year only 5.3 that didn't have DFM. The writer of said article and the person that made the claim conveniently can't count because they posted the VIN. The 8th digit was a "D" which meant its still the 5.3 with DFM. The 9th digit of the VIN was an "E" and the 9th digit isn't the engine code. At all.

You can't change the batteries in TPMS sensors. You have to replace the sensor.

For those interested, the Silverado and Sierra websites gained some new details to them. Biggest one being a visualizer of each truck and all trims and colors, on their respective sites. Still no power announcements. New 2027 Silverado | Pickup Truck | Chevrolet 2027 Next Generation Sierra 1500 | Future Vehicles | GMC Colors that stand out/I question. These could change closer to production as well, so my opinion based on the current state of the visualizer. Chevy - Trillium Green. Love it. Its trim locked to Custom Trail Boss, Trail Boss, ZR2 and High Country. Pacific Blue. Nice. But High Country only at the moment. Red. Only one red is shown, Apex Red (which is a nice color and is on the Trax and Trailblazer right now). GMC - Two reds. Cardinal (Red Hot) and Mesa (Apex). No green. WTF. Again. Its possible these may change some as production nears, and when the order guide launches.
