🙋🏼‍♂️ New owner here & wanted to say hey to everyone! I took delivery of my 2025 GMC Yukon XL AT4 Ultimate from the dealer this past Wednesday. Almost a full month sooner than the original ETA when I ordered it. This will at some point in the near future be converted into a wheelchair...

I've got the whole V6, LB4, 4300, engine apart! and Im trying to find the standard main cap diameter. I've looked all over the internet for specs on the main cap from the Kohlerpower manual, to calling MAHLE but they can't answer cause of the stupid virus. If anybody can help me out, PLEASE...

I have a 2017 GMC Acadia. Looking for tips and information.

Hi all, HELP? GMC Suburban 100 Pontiac engine 1955. CARBURETOR: Looking for a replacement / alternative carburetor. So, I'm still looking. It appears because it doesn't have a tag number no one can identify it. It is a WCD carter carb. I've dismantled it and have photos of all angles. If...

Hey fellow GMC/Chevy/Cadillac owners/repair men/enthusiasts. I am a father of 6 from the DFW area, I have owned 2 Suburbans and this is my first Yukon. I buy and drive them out of necessity (large family) and because they are safe and traditionally of superior quality to same size vehicles of...

Has anyone replaced their OEM GMC Terrain tint, I'm looking for window tinting. I've been looking online and read about Nano-tech window tint and body protection film? If nothing, I'm going to call another localist - so far nothing.

I hear that towing anything before 1000 miles is not recommended by a dealer. I towed a small empty trailer the other day (5x8) about 40 miles total. I was told that I should not have towed anything for the first 1000 miles. I am curious if any damage was done thanks.

I have been using Royal Purple 5w-30 for the past ~30k miles. Has anyone had issues with using a slightly heavier grade of oil? I tend to push my terrain pretty heavy. Where is the best place to get a new Oil drain screw? I nearly shredded my OEM one. (That bolt is hard to get a hold of)

Has anyone had the message - Reduced Engine Power - I got it twice within a week. Luckily by turning off and on, the messages stays off. I'm just over 120k miles. Also strange thing is that it could be my JET performance chip. I've had it installed over ~40k miles and no issue - until now? Has...

Hi everybody, I just bought a used 1994 GMC Sierra 1500 with 248000 miles, engine 350 with automatic transmission. I didn't notice anything until after I bought it (of course!). But the tranny whines a little when accelerating. Once you reach cruising speed the whine goes away or is at least...

I have a 92 gmc Sonoma. 4.3 vortec. 4 wheel drive. It started some time back after we rebuilt the engine. and transmission. It started like this. It would crank and drive fine, but after a little it would start jumping chugging and hesitating like it was loosing fuel. But then it wouldn't crank...

So I bought this Jimmy 4x4 that has been sitting for 2 years, threw in a battery and she started right up. It's running rough, the CEL/SES is on and so is the battery light. I went to plug in my OBD2 computer but it says the connection failed, tried a different one and same thing. Anyone have...

https://www.youtube.com/watch?v=nqTAI-LuBLY Hi. I'm new to the forum. I wanted to share this song I wrote called "DRIVING" which was considered for a global marketing campaign for GM in late 2014. GMC's legal affiliates required that I change the name from the original title "GMC". If you like...
