    Engine Coolant Level Dropping

    I was unable to find anything myself, but I do not claim to be a coolant leak detecting expert. Clearly the dealership isn’t either. They wanted me to drive 1,000 miles before I return so they can see if the coolant has dropped and if it has, where the dye is detected. More to come…

    Engine Coolant Level Dropping

    Update: I took my car back to the dealer who originally looked into this issue because the coolant has continued to leak. They struggle to find any leaks. Claim to have done a pressure test, which held pressure. Then I received this: “This is normal. Owner to add coolant in between oil change...

    Will 2021+ 22” wheels/tires fit stock height 2015-2020?

    With the mud flaps off, there is no rubbing at all. After a slight trim of the mud flap that had an unnecessary edge on it, those are back on with no rubbing at all. Stock height all the way around. Rides great. Love the larger tires to fill out the wheel well.

    Engine Coolant Level Dropping

    Hey everyone, I have a 2018 Tahoe, and about a year ago my coolant level was almost gone. I took it to the dealer, and they said it was unusual for it to go down as much as it had with such low miles (25k) on the car, however, they said no leaks were found. They filled me back up, and I went on...

    TPMS - Part Number 2015-2020 vs 2021+

    I purchased the part number 13540604, and they worked like a charm. 315mhz.

    Will 2021+ 22” wheels/tires fit stock height 2015-2020?

    Well, I went ahead and gave it a try. 2022 RST 22s with the 275/50r/22 tires. Fitment was great. Slight rub on my right front aftermarket mud flap which I easily trimmed to eliminate rub completely. As mentioned in other threads, the TPMS sensors in the 2021+ do not work in 2020 and earlier...

    TPMS - Part Number 2015-2020 vs 2021+

    Hey everyone, I just purchased a set of 2021 RST wheels that I put on my 2018 Tahoe, and the fitment is perfect. I am trying to figure out the TPMS situation now, and dealers are completely useless as they will not provide part numbers over the phone, and they want to gouge you on the price to...

    Will 2021+ 22” wheels/tires fit stock height 2015-2020?

    Thanks for the info. Maybe a better way to have asked this is: Has anyone tried putting a set of the 22-inch OEM wheels from a 2021+ on your 2015-2020 Tahoe/Yukon? If so, what was your experience?

    Will 2021+ 22” wheels/tires fit stock height 2015-2020?

    Hey everyone, I just picked up a set of stock 2021+ 22” wheels with factory tires. The tires are 275/50/22. This puts them closer to 33” than the stock 32” tires I have on now. I’d hate to go through the hassle of swapping out the wheel sensors and all if they won’t fit. I know the lug pattern...

    2019 Tahoe for towing. Difference between tow and max trailer package?

    Can someone take a picture of what the rear auto-leveling suspension looks like? My Monroney label shows that I have the Max Trailering Package...but my rear suspension looks to just be standard spring and shock. I am not seeing any bags back there. Is there a Max Trailering Package with...

    Getting Bilstein 5100's for front. Is upgrading rear shocks even worth it?

    For those that have installed, did the 5100s get rid of the boat rock now having the stiffer suspension? I’m still on the edge of doing it, as I’ve struggled to get a good idea of what to expect. I’m less concerned with the fact that it levels or can raise the front. I just want a better right...

    Getting Bilstein 5100's for front. Is upgrading rear shocks even worth it?

    I, too, am not a big fan of the ride. To me it feels like a boat that is constantly rocking. What's further surprising is that every bump in the road sounds like it is in the backseat with a major thumping sound. Almost like the shocks bottom out (though I know they are not).

    Getting Bilstein 5100's for front. Is upgrading rear shocks even worth it?

    While I cannot speak from experience, I am contemplating doing the same (5100s all around). The guy at 4WheelParts was of the impression that the rear shocks makes a huge difference on SUVs given the weights that the rears carry, compared to a truck that, unless hauling or towing, does not have...

    Anyone tried GTR Ultra 2 LEDs in 2015+ Tahoe/Suburban?

    Yes, I did notice they were not fully snug in there. I have not noticed any negative ancillary impacts with this being the case. All good so far.

    LED bulbs for 2017 Headlights

    I do not disagree with @petethepug about LED technology not being a perfect marriage to projectors, however....compared to stock halogen bulbs, there is no comparison. The LED bulbs provide significantly better light output improving visibility tenfold. You have to pay for it though. The $35...

    LED bulbs for 2017 Headlights

    Yes, that is the set I purchased. I do not use high beams often enough to warrant an upgrade, but they offer them for those as well. The high beams are not projector though, which I am sure you are aware.

    LED bulbs for 2017 Headlights

    I did the GTR 2 lights, and they have been great. See thread below. These are plug and play, no mods to the capsules. https://www.tahoeyukonforum.com/threads/anyone-tried-gtr-ultra-2-leds-in-2015-tahoe-suburban.116809/page-2#post-1439044

    Adaptive Cruse Control not working

    I know the exact button you are referring to. I was in the same boat. I thought I had ACC, but in fact it was just the crash detector. No ACC on my car. I have also only seen the crash detection engage once, and I have tested it out a few times. Wouldn't put much confidence in that feature, either.

    2020 Trail Boss 20-inch Wheels on 2018 Tahoe

    Hey everyone, I came across some new Trail Boss take-offs that I picked up. They came with the Dueler A/T 275/60/20 tires, but my wife did not want added noise to the ride. I swapped her new tires for my Dueler H/L 275/55/20 tires, and she is much happier with those (and it keeps the stock...

    Anyone tried GTR Ultra 2 LEDs in 2015+ Tahoe/Suburban?

    The car has not even been started since installing them. I think my wife put about 5 miles on her car during the month of April. The month of May should be different. Governor announced some lightened restrictions.

    Have you gotten around to installing the lights yet? Interested to hear your feedback on them.

    Engine Coolant Levels

    Coolant came in today. Got it topped off. Time will now have to tell. Maybe my wife will start driving it again now that the states are starting to life the stay at home orders. Maybe.

    Front or Rear or Both Sway Bar?

    Hey everyone, As I have seen a lot of others comment on, the Tahoe has terrible body roll. I installed a Hellwig rear sway bar on my truck, and it improved the body roll significantly. I'd like to do the same for my wife's Tahoe. Have any of you all installed one or both on your vehicles? My...
