Original owner, all stock 2015 2500HD WT 6.0 gas 190k miles. Cylinder 3 exhaust valve tip almost gone.
Engine developed a low noise valve tick on start up and idle, 3k miles later, louder and at all rpms. Intermittent (twice) P0303. Removed valve cover, rocker arm and observed damaged valve. Roller lifter and cam journal showed no signs of damage.
Of the eight valves, one destroyed and three others showing wear( pic 3) Inspected passenger cylinder head valve bank, no signs of wear or damage. Oil stain seen through exhaust port.
Informed GM and assigned case
#9-5190338716. The truck has been a solid performer and provides great service. The short years and high mileage may indicate future issues with valve lots that may be below specification.
My plan is to replace all valve parts including lifters. Should GM want to inspect these parts, I will make them available upon request.
I have a 2015 Chevy Silverado Work Truck 4wd with the 5.3l V8. On my truck, I have a manual transfer case on the floor similar to older trucks. All of a sudden my 4wd light on the dash will come on and my truck starts whining and grinding like it wants to go into 4wd. My shifter for 4wd is positioned in the 2wd position, and the light is still on. I can put it into 4wd and then back into 2wd and the light will go off and 30-60 seconds later the 4wd light will be back on. Now even when I turn it on sometimes the 4wd light comes on immediately. Has anyone else had this problem? If so what did they do for repairs? Anything helps
2015 Silverado 2500HD W/T "Modernizing" - Help! Instrument Cluster Upgrade, Backup Camera Upgrade, Factory Nav 8" Screen UpgradeBy ChadwickDMAX
Hey guys, new member here. I decided to join this forum because of how awesome the community is on providing answers and solutions to somewhat elusive topics elsewhere on the internet. I'm excited to be a part of this awesome community and help contribute when possible!
I currently own a 2015 Silverado 2500HD W/T (work truck). Although these trucks come well-equipped in comparison to previous generation work trucks, there are still some features that us W/T guys are missing that I would like to upgrade to. So let's call this the "W/T Modernization" thread. My aim is to provide a solid thread to answer some of my questions and also help other W/T owners find the information they're looking for in regards to upgrading their truck.
Here is a list of mods I would like to accomplish:
- OEM 8" Touchscreen display w/ IO5/6 HMI module for Factory Nav. (LT+ models)
- LCD Color-display instrument cluster. (LT+ models)
- OEM Steering Wheel Controls (SWC) on the right side of steering wheel.
- OEM style tailgate backup camera.
- Z71 style front grille approach camera.
I have found a good amount of information so far on upgrading these trucks from an IO4 to an IO6 HMI module in order to support an 8" OEM touchscreen along with factory nav, Apple CarPlay, etc. From my understanding, there are companies you can contact to purchase full plug & play kits for about $1k. This seems to be the easiest and most expensive way. I attempted a DIY approach by buying an OEM take-off 8" display on eBay, but the problem is in the HMI module. These need to be pre-programmed in order to plug and play and there is no open-source software to do so.
The issues I'm having is obtaining clear, concise information on performing the remaining upgrades.
Instrument Cluster / Steering Wheel Control Upgrade:
- So far I have purchased an OEM take-off instrument cluster from a Z71 package truck of the same year. This new cluster swapped out and powered up from the original harness just fine. Upon startup, the display states "Action Required: Cluster Programming" along with a plethora of service warnings such as "Rear Axle, TPMS, Front Camera" etc. Unlike the original cluster which has a manual push-pin selector to clear service codes and change menus, the new cluster does not have a manual selector. This leads me to assume that the only way to interface with the cluster is by steering wheel controls.
My W/T has cruise control on the left side of the steering wheel which is interfacing on the new cluster but does not have a right side control/selector. Can I simply add additional SWC selector to the right side of my existing steering wheel or do I need to purchase a whole new steering wheel? Is this plug and play? Once installed, will it properly interface with the new cluster? How do you properly program the new cluster? is it auto-programmable or do I have to take it in/send it off to somewhere?
- Rear OEM tailgate handle back-up camera is a necessity; especially since the truck is a crew cab long bed. Does anyone know if these trucks in this year come pre-wired to add on a tailgate camera? Will it properly interface with the new 8" screen? This is a priority over front camera which is just added luxury. Same questions apply to front camera. If anyone can point us in the right direction for a quality OEM style camera, that would be awesome.
Thanks a ton,

Chevy wants you work truck shoppers to know that the new 2019 4500HD/5500HD/6500HD trucks now come with a flowtie. A flowtie is a Chevy bowtie emblem that allows air to pass through and thus cool the engine area.
Chevy says that during Z/28 aerodynamics testing, engineers noticed that the bowtie on the grille was blocking cooling air. Engineer Richard Quinn went at the bowtie with a cut-off wheel making slots. He installed the new prototype "flowtie" on the grille and a retest proved that it allowed more air into the engine, lowering engine fluid temperatures during extended track sessions. Now your work truck can have that same benefit.
Chevy work truck Design Manager Kevin O’Donnell says, “The flowtie is an elegant solution. And it’s going to work on the Silverado exactly the way it does on Camaro."
I was wondering about upgrading my small cluster in my 2015 sierra WT to the multi-color/4.2 inch cluster. Is this something that is possible? The connectors are the same on the back so I guess all the wiring is there and its just a matter of getting the BCM programmed. Any info would be great!
