    Fuel Pump Access Door in floor of 2007-2014 models

    For the gas tank on these machines I'd want to drop the tank and clean everything around the tank. Dirt, sand, gravel all build up over time, and the straps seem to be designed to rust too. Sure be nice if the tank happened to be low on gas too.

    Dealer Service History - Would you buy?

    Looks like the original owner was real picky, or a relative of someone at the dealership, or both. At that mileage I'd get the transmission serviced if you buy it. Pretty classy vehicle!

    2017 Tahoe 6L80 Transmission Issue

    First thing I'd do is unhook the battery for a couple hours, hit the brakes to have the lights totally bleed the circuits. See what happens when restarted and idled for a few minutes. Sees to fix a lot of issues in these machines.

    Best and MostReliable Engine

    I guess we really lucked out with our 2019, maybe. Sales were real slow, got a super deal on the machine on the lot and it was exactly what we were looking for. For me it's like driving a bus but we bought it for a highway machine and we load it up and take off every so often.

    Best and MostReliable Engine

    If price is not a barrier, I'd go with the diesel at this time. The current troublesome technology just to save a mpg or so with the gas engines is not worth the anxiety. But it would also depend on how long you intend to keep the vehicle. Diesel for the long run.

    REAR AC Lines

    I'm thankful that I have read about this problem on the forum here. I get under there now and then and wash all those lines off. Still look new so far. I wouldn't have even thought those lines go clear back there and tuck up out of sight. GM does some weird things along this line, plastic...

    What’s wrong with those tires on the pictures?

    Might be some underinflation there too especially if they were up front. I keep my tires at 37 psi cold, will go to 40 when good and hot. Goodyears are wearing perfect, maybe a bit too fast though.

    Is this frame too late to save ?

    Maybe worst part might be the body mount areas in the floor pan. Those areas are shaped so they trap water/salt and you can't actually see the damage until it's really a mess. See the same thing you're looking at here in Ohio. Clean/paint that frame as much as possible, then I start shooting...

    2025 yukon debut and predictions

    The Traverse and Acadia are built in the USA so the marketing dollars go to the higher profit margin vehicles I suppose. And I like how they promote that Turbo High Output motor without mentioning it's a four banger. Be a good machine for leasing, 328hp out of a 150 cubic inch motor.

    Body mount bolt washers rusted away - replacements ?

    Here in the snow belt I've ran into that a couple times over the years. Gets to be a real mess. I recently took all the bolts out, cleaned, and put a thick coat of Never Seize on them, wire brushed and painted the big washers. Just after 5 years they were starting to look bad, Tahoe never in snow.

    2005 Suspension Question

    After 24 years it might be time for some new rubber bushings. Body mount cushions for one. Certain tires can wear and ruin the ride too.

    Loosing coolant. Underhood coolant smell

    Not usually. Not uncommon to have a leak that doesn't show when cold, or hot. When in the warm up stage as pressure comes up it seeps until expansion seals it. But you need to pressurize the system cold and look real hard for the spot.

    2019 Tahoe transmission service at 28k miles

    I dropped the exhaust pipes so I could bring the pan straight down. I'm pretty good at tilting those pans and pouring oil all over me even with the pan mostly drained. And I wanted to remove those nuts on the exhaust manifolds anyway and Never Sieze them real good. Those six nuts were really...

    2019 Tahoe transmission service at 28k miles

    I've been seeing all the problems with the 6l80 transmissions lately, son's GMC took a dump at 100k miles, scared me some. Decided to do a mid cycle service on our Tahoe to see what it looks like. Pretty surprised (nice) to see the inside of the pan. Also changed the thermo valve while I was...

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    Spent most of yesterday looking for a squeak/groan noise on the left rear of the Tahoe. Unbolted everything thing that moved, lubed the sway bar frame bushings. No luck. I see the spring itself is mounted in rubber top and bottom, only thing I didn't do anything with. This is just weird. Did...

    Need Advice - 2018 Yukon Denali - needs new engine

    First thing I'd do is charge that battery. Then I'd unhook the fan/alt belt, start the motor, and listen for any serious noises from the engine by itself.

    New Vehicle - Service Suggestions

    One other thing, might seem a bit odd, check the bolts/pins that hold the disc brake pads on. They let the caliper move to keep it centered and they sure will get corroded and stick, screws up the braking some and unevenly wears the pads much quicker.

    Odd behavior, possibly due to damaged battery?

    Harbor Freight has a battery load tester for real reasonable money. Look for their 25% discount coupon. It will put a 150 amp load on the battery for 10 seconds to get a good look at the condition. It gets hot. But I got a new Delco battery put in our 2019 last year at our dealer. That battery...

    Please Help: What does this Carfax Report tell me?

    Looks like some nagging problems in a machine expected to be perfect. And 2021 isn't known to be a perfect year for those either.

    Instrument cluster

    Cluster problems are pretty common in those years, but I'd first suspect a bad connection or cable at the battery or grounding points.

    I'm guessing my trans is dead?

    I'd say you got good service out of that trans. but it's time is up. Fluid smell like it's burnt or just the regular stinky stuff?

    Rusty Calipers - issue or just cosmetics

    Is this a machine from Michigan? I'd look pretty close underneath the Esky for rust on and inside the frame, front suspension pieces, rear cross members, etc. Rusty looking calipers is not too common on newer GM machines with the silver looking coatings.

    Road trip MPG, 2019 Tahoe

    I checked that readout a couple times before and it was within a tenth or so on the averages. Very little down time or city driving with this trip. The technology does work, if they could just get the reliabilty improved.

    Road trip MPG, 2019 Tahoe

    Took a 500 mile road trip today, Sunday. Light to medium traffic, two people with luggage, no drag racing, no big hurry, mostly at a couple above the speed limit. 2019 Tahoe, 5.3, 3:08 gear, mid grade gas. I'm pretty satisfied with this:
