    Lifter issues - What Oil Did You Use?

    I turned off start-stop every time (I remembered). I don’t see how start-stop can help engine/starter/battery life while saving a very small amount of gas. Irony is when I wanted it to work-waiting in a long line of cars, for a train, etc the start stop would never turn the engine off. Pull up...

    Tahoe Z71 vs premier suspension

    Depends on if either or both have air ride & magneride.

    Magnetic ride suspension VS standard

    I guess it depends on what you are after. My 2016 was standard suspension, which I changed to Bilstein struts and shocks when OEM got worn. I thought that setup was the best. Fast forward to my now current Z71 with air suspension and magneride. I have experienced the previous generation...

    Magnetic ride suspension VS standard

    Magnetic ride is definitely noticeable. Bumps are much more controlled. Handling is much better.

    Lifter issues - What Oil Did You Use?

    For those that had or have lifter issues (the dreaded collapsed lifter) what oil and filter did you use before the problem? What oil and filter do you use now? I am wondering after a comment made by the dealership mechanic as my truck was in the shop for a #6 collapsed lifter. I have sworn by...

    2021 Tahoe with 6k miles mine has already had a head off

    I think we have a different system as the engine can go from 2 to 8 cylinders, and anything in between as commanded by the engine management computer.

    Another 2021 z71 engine problem?

    If the engine shakes, especially when warm, probably a bad lifter. Mine developed same symptom. Was in shop LONG TIME waiting on parts. :( Now how do you get the tranny in neutral without the engine running? Myself and the tow-truck operator could’t figure it out. Turn the engine off and...

    2021 Yukon 3rd Row Seat Cover Reco?

    I’ve had good experience in the past with Cover King. Might look at them.

    Aftermarket wheels

    I’m not taking shots but just want to set the record straight — you said 20x9 with a 22” tire? o_O

    How about some gas mileage reports?

    21 Tahoe Z71. 20-23mpg highway 16 around town, but as low as 13mpg in winter around town. Seems like the 21 gets worse than the 16 LT got. Still a great truck anway—maybe not broken in yet!

    Windshield Mounted Rear-view Camera Mirror?

    What is the option or RPO code?

    Front & Rear Diff Lube?

    Found out the RPO codes from the QR code inside the driver door jamb. RPO codes are no longer inside the glove box door. I indeed have the G86 rear diff. Not sure the part number or type of fluid? I want to change it so soon for PM maintenance and get all the initial wear particles flushed...

    RPO Codes?

    Thanks! Somewhat combersome but I got it.

    Front & Rear Diff Lube?

    I would like to do some PM on my 2021 Z71 Tahoe, but I can’t find the type of front & rear differential fluid. Manual says “Consult dealer”, other oil sites don’t have anything listed. Surely someone has changed fluid by now. What did you use? To make matters worse, I can’t tell if I have...

    RPO Codes?

    Where can I find the RPO codes for my vehicle? Before, they were located on a sticker inside the glove box door. They aren’t there now. I’ve looked high and low, and did a giggle search, to no avail. Any ideas?

    Raptor tire on Z71 Tahoe 21

    I don’t think 17s will clear the brakes—especially the fronts.

    Windshield Mounted Rear-view Camera Mirror?

    Saw one of these in a new Sierra, and saw them mentioned for the new Tahoe PPV/SSV. I have not seen the option for the civilian Tahoe or any retrofit kit. Anyone see the kit or option from GM or the aftermarket? Comes in handy when the back is filled up!

    2021 Z71 Tahoe Engine Failure Tear Down 4k Miles

    Is that a Z71? I thought all Z71s had red tow hooks, black chrome trim, Z71 badges on the front fender just behind the hood, and Z71 running boards?

    Mud Flaps and Power Running Boards

    I ordered and installed Weathertech on a Z71 with stationary boards. When I was ordering them, if you have power running boards the website would not let you order a front set of splash guards.

    Tire size for 21 Tahoe Z71

    what offset rims? 22” would move the tire sidewall up and perhaps above the control arm.

    Tire size for 21 Tahoe Z71

    First time I changed oil on the 2021 Tahoe Z71, I noticed the front tire is awfully close to the upper A arm. There is only about 3/4” + or - between the two (about a hand width-I could stick my hand up there and rub both at the same time). I don’t think you will get much wider than a 285 or...

    Gas Capacity

    Mostly true. The new pumps and tanks have a “reservior” around them for cooling. I.e they are designed to keep about 1 gallon of fuel around the pump at all times for cooling. It was interesting to see when I dropped the tank on my 2016. I’m sure the 2021 is the same way.

    Vehicle build sheet

    or a Toyota, or a .... They ALL have issues. TSBs galore. (And this coming from a Toyota, former Nissan, Ford, Honda, Oldsmobile, Buick, Chevrolet, etc owner/driver.). With the complexities of today’s vehicles, 22+ computers and more lines of code than a commercial airplane (and we see what...
