None, here. Dealer could smell it too, ran all sorts of test on the coolant system. Never set a code, never a sign of a leak anywhere, my coolant was never found to be low in 20,000 miles. Just had that coolant smell. I sold mine to a good friend of mine, when I bought my 23 AT4X which only come with 6.2L gas engines. But I would have bought the diesel again had it been offered in the X .

Tires are 305/60R18. Wheel is 18x9+20. ‘That same tire I originally had mounted on a 18x9+1 which I had on my 2021 AT4, which that setup did have a rub issue on the 2021. I ordered today that same 18x9+20 Fuel covert wheel, only in all black with a set of 305/65R18 Falken At3 tires. The 2023 trucks with the AEV front bumper come with a 33.2” tire, the Recons were only 32.4” tall tire. ‘Going to try and keep the 305 width and get the height back up a little over 33”. The Falkens spec 33.4” tall. -

Sold my 2021 AT4 Carbon pro 1500 Duramax tonight, picking up my new 2023 AT4X later this morning . Dealer sent me a few pics yesterday right after it came off the transport. -
What have u done to your 2020 hd
cc1999 replied to mkeddie's topic in 2020-2024 Silverado HD & Sierra HD Mods
Got my new HD a week and half ago, so far got the windows tinted, my black gmc logo’s installed, headache rack and toolbox installed. Day 1 hot her home and got started . Getting started. Next came the window tint. Next came getting the rack and tool box off my old 2015 Ram 2500 all moved over and setup on my 2023 GMC HD . Now on the GMC 2500. -
I ordered Fuel covert 18x9+20 with Nitto Recon tires 295/70R18 . based on my math calculations. I should end up really flush with my fenders or very close to it. Which is what I am after. Custom Wheel offsets has a great gallery for seeing what different combinations look like. May not find the exact wheel tire combo your wanting but you can find sizes and offsets like;y similar to what your looking for in similar size and offset with similar size tires. https://www.customwheeloffset.com/cart

Recent pic of my 1500 AT4 Duramax doing a little work. Here is one of my new 2023 HD Duramax. -
cc1999 started following 3.0 Duramax smelling anti freeze after parked

My AT4 now has 10k miles and ever since the first oil change around 7000 miles mine has had the same coolant smell everyone is talking about. I have had other mechanical minded buddies comment on it as well. At first I thought I was imagining it, when I could not find any visible problems. Same as everyone else no codes, no leaks found anywhere, coolant levels have remained the same since I first noticed it about 3000 miles ago.

Those are the OEM boards that come on AT4s, I think they were possibly part of one of the option packages on the truck. You probably could get them from a GMC dealer . I would imagine they are offered as an accessory item from GMC parts. -

Added body color wheel opening moldings to my AT4. ‘This was about the only option my AT4 was missing. GMC offers these repainted ready to install for around $600 i think they really clean up the look or lines of the truck. Also helps make your wheels and tires look more proportional to fender openings. -
Got them clearanced , no problem. Took about 30 min for each front caliber. Took about half that bulge off. Rides and drives great. I am a happy camper now.
