    2019 Tahoe corroded freon tube leak - manfr design flaw

    Heh, I guess when they design them like that an inanimate piece of tubing IS a wear item!! :mad:

    20 inch rims on PPV tahoe

    The larger diameter will definitely drop the effective gear ratio, which will affect acceleration. Add to that the increased unsprung weight. It takes a LOT more energy to start those big tires rotating. I'll bet you feel it. OTOH, you'll gain some top end, albeit the speedo will say the...

    Advice Needed re Replacing Front Strut (Shock?) on 2017 Tahoe

    They're actually a shock absorber, although they are available as an assembly with the spring and attaching parts in a strut-like assembly. Even as a separate part, magnetic ride shocks aren't cheap, They seem to run in the $300 range for aftermarket parts, and the strut assembly in the...

    If you won the lottery and you could have any truck, what would you choose?

    Bentley Flying Spur Speed Edition 12. Need the 4-door so the pups can travel with us. :rofl:

    2018 oil cooler assembly replacement?

    Attempt to replace No. 1 was a fail. It seems the Lisle fuel line quick disconnect tool (P/N 37000) will not work with these lines. GM calls for tool CH-41769 to do the job, so I've ordered one. It should be here midweek next week. Fingers crossed. Just in case, I've also ordered P/N...

    What would you do to stand out?

    Driver's side spotlight. OR, just get a retired PPV: ;)

    2018 oil cooler assembly replacement?

    Ours is 2WD, so no front diff. It looked like it might not be too bad, but I've had 'gotcha's' before. The lines run from the driver side of the engine block just above the oil filter housing, forward to just to the front of the engine, then turn right across the front of the engine...

    Retired 2019 PPV Tahoe. Rear windows inoperable

    On the 2019 PPV, it looks like the SEO option 6N5 (SWITCHES – REAR WINDOW INOPERATIVE) makes the rear door windows inoperable at the door switch. Check your SPID label, possibly on the glove box door. IIRC, that will require a BCM update to remedy.

    2018 oil cooler assembly replacement?

    Saw a couple of oil spots under the front of our '18 PPV. I climbed under the hood to discover that one of the oil cooler lines where the rubber hose is swedged to the aluminum tubing is leaking. I have a new line assembly enroute, and haven't had a look in the FSM yet, but wanted to see if...

    Spark plug change @ 99,500 miles 2019 Suburban 5.3

    Our 2010 PPV was similar. right rear plug was a huge PITA to get to and pull. We did plugs and wires at about 90K miles, and, honestly, I couldn't tell much difference at all. Our 2018 PPV is at 98K miles, and AFAIK, it still has the OEM plugs in it. Still runs great.

    2021 Tahoe PPV massive oem brakes, 16"

    Hopefully, they do better than the phenolic pistons on the Mustang SVO brakes!! They worked great until they didn't. Common failure mode was a seized piston in the caliper, usually after you stopped. :mad:

    2011 Chevy Tahoe best LED Headlights???

    Note that the lights Joseph shows will NOT fit a Tahoe without significant surgery to the radiator support. I used a set that had the passive heat sinks (they look like metal ribbons coming off the back) and those just fit. The headlight assembly has to come out to install them, but they do...

    2010 Tahoe PPV cylinder misfire

    Truck went to the new owner last week. He's already installed the spare front suspension bits that went with it, and they're diving into the engine issue later. When they put a scanner on it the only thing they could find odd was that the fuel sensor was showing 2% alcohol. We run regular (93...

    “CAI” cause of RPM fluctuation?

    Agreed. That plug looks used, but not abused. I replaced the plugs on our '10 Tahoe when we got it at ~60K miles, just because. While they didn't look as used as the one you show, the new plugs made zero difference in how the truck ran.
