    2011 Denali Radiator Replacement

    If your doing that, I would also replace the hoses including the dorman metal Y hose (better replacement than the plastic one) and plastic heater tees that are known to break. I just replaced all my hoses and tees and thermostat a couple of months ago. My radiator was fine. I can't now but I...

    So confused!

    Does it turn off and then start back up again totally fine or is it like that permanently now? I am not a great diagnostics guys but an ok find a video and "fix" guy. However, based on what I have read around here, it sounds like it could be a ground issue that once hot, causes some issues...

    Valve tick or normal sound?

    Just an update. I took the family of 7 (it was tight!) down to the OBX for 2 weeks (first 2 week vacation ever!) in the Yukon and it did perfect! I averaged around 16 MPG with it loaded including a small rear trailer hitch basket. Noise did not get a better or worse. I even threw in some B12...

    4x4 Maintenance

    Good for you letting the family help! I really need to do better with that. I have very little time so I always end up rushing and then get frustrated and then they do not want to help me anymore lol. I need to learn to relax and know it WILL take longer but try and let them help more. Nice...

    2016 Yukon XL repairs for 100k miles

    Your plan sounds good. As others have recommended, please send pictures of your rear because if it has been "leaking" for a while you may want to have that changed as it could be a little low on oil. I would keep the stock suspension and replace with OEM from rockauto or Arnott as others on...

    Purchased a 2007 Yukon XL, now to make it reliable!

    That’s exactly what my neighbor had but like 40 years older lol. They were probably a size or two too small but they got me to get the job done!

    Purchased a 2007 Yukon XL, now to make it reliable!

    Any tricks on the lower radiator hose spring clamp at the radiator? I struggled for way too long with a pair of channel locks to get the spring clamp squeezed and slide over the new rubber hose. I just couldn’t get a good angle. Ended up borrowing a neighbors old school locking hose clamps and...

    Engine Pinging

    Where did you get the motor that they gave a new one via the warranty? Seems like many places fight tooth and nail on warranties and it’s good to know some good ones exist! Glad it worked out for you!

    No, squeal was from the front.

    Purchased a 2007 Yukon XL, now to make it reliable!

    What brand did you go with? One of my rotors was already missing the screw when I did mine. I used centric premium and glazed them while bedding them in and could not get rid of the squeal. Switched to Wagner high performance truck pads and I have to say, the centrics stopped better unfortunately.

    Valve tick or normal sound?

    Well I finally got my Blackstone lab report back and it seems good so far. My next steps I guess are to take the valve covers off and take a look around if anyone has any other insights or suggestions it would be appreciated!

    “Normal” oil pressure on Gauge-2013 Tahoe

    For reference, mine is about that and maybe slightly higher. From what I’ve read on here it is normal. My 2011 xl Denali with 101500 mi will be about 22-25 at hot idle and 37-43 when driving. It’s around 50 at start up and goes up to 60 when first starting to drive until it gets hot.

    Quick help on a road trip - Updated: Coolant System & Belt

    Well I’m trying to slowly catch up on maintenance and I finally changed all the hoses, tees, thermostat and coolant today. It’s only been almost two years lol. I was most concerned about the tees but those things popped off in 15 secs each! Everything else went very smooth until it was time to...

    Valve tick or normal sound?

    All the exhaust bolts are there. I put a wrench on them to try and move them to see if they would move or break but nothing. Doesn’t mean they aren’t leaking but seems ok. I did actually get a sample from my last oil change and sent it to j be Blackstone. However, I did not obtain it the best...

    2007 Chevrolet Tahoe Tick at Idle

    As others have said and from my research on here your oil pressure is good and mine is just about the exact same on my 2011 xl 6.2. I actually just posted a video in my thread with what my noise is as well. I am trying to figure out what’s next. Check your exhaust bolts as noted above, mine...

    2013 Yukon Engine Knock...

    I just listened to yours back to back against mine and it sounds pretty similar but mine does not make that sound driving at all. Mine is not as loud from above but almost as loud in the wheel well. I’m not sure what to do yet on mine either. I posted a new video in my thread.

    Valve tick or normal sound?

    All, I wanted to update this thread with a new video after I just changed the oil from Valvoline 5w30 synthetic to Mobile 1 5w30 syn with the same purlator boss filter. I am only at 101600 miles as I do not drive the truck much. However, I want to take it from PA to OBX in september and want...

    Seat Swap Captains for Bench

    14 LTZ Shutter/shake/ vibration under light throttle

    Yep, sounds like the afm system is what you are feeling. Couple options: range device will plug in to your obd2 port and keep that from occuring but need to be taken out to pass inspections. It’s around $240 on Amazon. There is a place/guy you can send your pcm to I believe that will turn it...

    Custom Tune Review!

    Thanks for the info Nick! I will mess around with the Tech2 some more for seeing what else I can monitor but probably just plan on doing the valve body. I wanted to try and confirm that before spending the money and time but I’m still not confident in the trans adapt reset which is required...

    Custom Tune Review!

    Its my 2011 6l80 AWD denali transmission. I had it tuned and the tuner seemed to make it a little better but I am trying to confirm what exactly is happening on the 3-2 down shifts as it seems to bang a little when going into gear. This only happens after the transmission seems to hit around...

    Custom Tune Review!

    I just wanted to bump this in case anyone missed it. I am looking for guidance on the how to best use the Tech2 to try and figure my tranny out. Maybe @NickTransmissions is away or I need to put this in the transmission thread but any advice is appreciated.
