    23 Tahoe High Country drivers side mirror got wacked, only broke the glass.

    Put a new glass on a Cruze last week. Aftermarket replacement snapped right in and they have electrical connections like OE. Not sure they are available for the '23 models yet. Easy install.

    Time for new battery, need info, 2019 Tahoe

    Got it swapped out yesterday. Spent more time cleaning everything up than actually changing the battery. That's one heavy chunk too.

    Delco battery date coding?

    I can decode most replacement brand batteries but this Delco has me stumped. Anybody know how these numbers work on a Delco?

    Suggestions for code scanner tech tool?

    Looking for a basic code scanner for the newer GM vehicles. I have the 2019 Tahoe, son has a 2017 with the same drive train. Not looking for bi-directional operation or to reprogram anything, just pull codes, reset SES, see live monitoring inputs. I see several that look good, priced right, but...

    Oops, turned key on with MAF unplugged, service engine light on

    It fixed itself. Took 5 restarts looks like. I need to be more careful when I do stuff to that machine. Probably need to get a scanner for this newer OBD sys. too. Son has a 2017 Sierra with the same drivetrain as the Tahoe. (See new post)

    Oops, turned key on with MAF unplugged, service engine light on

    Changing battery and air filter today. Hooked up 12 standby power while battery was unhooked but after I put the new air filter in I turned on the key to get mileage with the MAF unhooked. Now I see the service engine light on, also see the oil pressure was reading high on the first drive...

    Trans/Transfercase fluid change

    If that trans fluid is not nice and red I'd change it. I'd want to see what's in the bottom of the pan too.

    Need help with power inverter

    The inverter in our '19 is good for 400 watts I think. Still not near enough. Divide your watts by 12 and you'll see that little heat gun pulls a lot of amps in the car DC circuit.

    Time for new battery, need info, 2019 Tahoe

    I'm into 3rd gens myself, not much into racing though: On the Tahoe battery I'm thinking I'll stick with the OE conventional battery. This is our road/vacation machine and it has to be dependable.

    Time for new battery, need info, 2019 Tahoe

    For our 2019 Tahoe. OE battery is a 94RPG or H7 size flooded acid standard type battery. Looking at new batteries I see that for a few more dollars I can get the same physical sized AGM H7 with a better amp rating and better warranty (4 year free replacement). But I'm not really up to date on...

    5.3 Guys, opinion on oil change intervals

    I read somewhere that German oil specs are some different that over here in the US? Could have something to do with longer intervals for the German cars.

    Front brakes both sides heating up and dragging

    One thing you can try is get the brakes hot and dragging, open a bleeder and see if you get a spurt of fluid. That would point to a restriction in the lines rather than a mechanical binding. See this in motorcycles pretty often.

    Battery Replacement a Professional Job?!

    Any time I cut the power to any vehicle I hook up a jumper battery to keep all the memories powered up.

    Is it possible to keep truck too long?

    Some of this depends on where you live. Up north in the rust belt, maybe time to let go. Southern areas maybe spend some money to get it up to par and drive it another 100k. Does your machine have the cylinder de-activation deal? Any work done on that setup? That could soon lead to an...

    Too much rust?

    Critical points for rust are at the body supports where there are the rubber cushions that sit on the frame. The supports that are part of the floor boards can rust and darn near impossible to actually repair. Also look at the frame cross members that can get seriously rusted too, mostly in the...

    Need help!

    Check your oil, see if the oil on the stick smells like gas.

    I thought I blew up my transmission because my truck would not move …….

    Kind of amazes me the torque values on some of these bolts and nuts. Old days just pull it tight and run it, 150 ftlbs is more than "tight."

    Tips and tricks to have a nice ride.

    With no warranty I'd disable the AFM cylinder de-activation, get a tune module to improve the torque converter lockup, and do a trans. filter, fluid change, and put the revised trans cooling control valve as mentioned above. Should have a long term reliable machine with this.

    Main Bearing Failure with 6.2L at 3,200 miles

    I wonder if it's core shift due to heat cycles, water splash, stress. A 0.001 shift would wreck this modern engine pretty quick. Darn shame to do a heart transplant on a brand new machine like that though.

    Front bumper fascia lower molding removal

    Just about any of that type trim is a push on piece. Try prying at a corner and look behind it for a push in tab. If you see a gray adhesive strip it's 3M trim tape and that stuff is tough.

    Best place for instrument Cluster repair?

    Son's Silverado cluster started messing up,finally most of the gauges and readouts quit, most lights were out. Sent the cluster to a place called Circuit Board Medics in SC. Full rebuild and new lighting. $180 and 20 shipping both ways. That was last year, still working fine.

    Piston Rings

    I'd stick it in the bore and measure, If 15 thou or more I run with it. If under that I'd do more research.

    Ok to put 20" rims on 2024 Tahoe High Country that came with 22" rims

    Might want to match the outer tire diameter to the stock tires to keep the various computer systems happy. Smaller wheels with bigger tires would probably give a nicer ride too.

    Engine issues

    Might try some of these. GM created this for the early cars with aluminum heads on the cast iron blocks that were having coolant leads due to the expansion differences of the metals. I've read it was a factory install in the Cadillacs for a couple years.
