    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.

    Swapping headlight bulbs…HOW THE..?

    We put LED on our 2010, and our 2012 9C1, so I know how nice they are. the caprice required just a little hand gymnastics to get into and out of the headlight module. The 2010 required removal of the headlight module to get to the high beam, and then, required a certain type of bulb (one...

    Tahoe PPV Deflector installed on 15 Suburban (shorter lower valance that comes on Police model)

    Funny, I have a 'regular' Tahoe air deflector headed my way. I wanted to get a deeper one on the truck to hopefully gain some mileage. We put a Suburban/Tahoe air deflector on our 2002 GMC 2500HD when it was new, and we gained a solid and repeatable 1 MPG. I figure if we can get that out of...

    2017 Chevy Tahoe PPV Auto Lights

    That option can also be disabled via a RPO option. You'll probably want to check the options on the SPID sheet for your truck. Our 2010 PPV has all the parts, but it's not enabled, while it is operational on our 2018. If disabled by a RPO code, AFAIK, the only way to re-enable it is via a...

    Swapping headlight bulbs…HOW THE..?

    Yeah, the manufacturers are doing their best to make you come to THEM for the simplest things now, like replacing a headlight bulb. We're holding off on the LED upgrades on our '18 until after my shoulder joint is replaced. It's just to painful to pull all those bolts at this point in time...

    Fans run like the engine is overheating, coolant gauge reads no temperature, A/C disengaged.

    Well, that was quite the PITA! We rolled the Tahoe out to the shop today to do the temp sensor replacement. While you can see the radiator drain plug, you can't touch it without significant disassembly of the front of the truck. Checking with the FSM, on hopefully the quickest route to...

    Fans run like the engine is overheating, coolant gauge reads no temperature, A/C disengaged.

    Why does GM seem to have these things happen? Like the crap motor mounts and dash panels on the NVS Tahoes, to this stuff? I JUST had this happen on our new-to-us 2018 Tahoe. Bringing my bride back from cataract surgery I noticed that the temp gauge was reading below 160 degrees and the...

    Swapping headlight bulbs…HOW THE..?

    Like Sparks says: 'Remove the front bumper cover' is step 1. That's like a 30+/- bolt/clip proposition. You might be able to get by by just removing the inner fender liner, but I doubt that. Since you have an aftermarket bumper, who knows what that process is?

    Steering wheel swap volume controls

    I don't need heated wheels here. Maybe cooled, but not heated. What I'd like is the radio volume controls on the wheel. I really miss that on the new one. GM says their radio volume control module is 'plug and play', so I may go for it for the better wheel and hope the volume controls work...

    2007 PPV Tahoe magnaflow catback help

    That cat-back kit looks pretty complete. Like B-train says, the front attachment is a ball socket that uses no gaskets. The only potential issue could be if the nuts are rusted on the studs. You'll probably want to hose the stud down with Liquid Wrench/WD40, or some other good penetrating oil...

    2010 Tahoe PPV cylinder misfire

    I did clean the MAF sensor, and no change, although if it were the MAF sensor, I'd expect it to be a random miss, but it seems to be consistently-posting cyl7. It could be the injector, but I do hear it clicking, and it sounds just like the others. We have already replaced it for DD duties...
