    Comtemplating 08 Hybrid, 80k miles

    As my wife and I search for a new to us vehicle after her beloved Hyundai veracruz was totalled by an 18 year old I am constantly unimpressed with what is available in our price range.... Then, I found a 08 Yukon denali hybrid with the 6.0. I have owned 3 different LS engine trucks, an 8.1...

    Changed battery, now sunroof is DOA?

    Just like the title says, I changed the battery on our 2007 xl denali and afterwards I have no movement from the sunroof. I hear an electrical click so I feel like its trying to open. I obviously checked the sunroof fuse and its fine. I have also read this...

    Stalled randomly while driving, wouldn't restart for an hour. PLEASE HELP!

    I had the exact same problem/symptoms on a different GM platform and it was the crank position sensor. If I remember right it was super cheap, I would start there. Also, know cel codes, may have had one "deeper" but my cheap scanner at the time wouldn't read it.

    Yeah they are an issue for all of the motors of this style 4.8-6.2 The YouTube vid for the 5.3 Chevy isnt identical to your vehicle but it's super close.

    Low oil pressure on 6.2l 2007 escalade

    Had the exact same problem with our 07 denali (6.2) I swapped sensor, check for screen, tried diff filters/oils. Then bit the bullet and tore into it. I checked o ring first and when I took it out (again, probably 6 hours, never dropped an oil pan before) it was super obvious. It was flattened...

    Engine Oil Pressure Sensor replacement?

    They are a pain to get to, so if you are doing it, or paying to have it done, replace the filter under it. It can cause problems, and super cheap to do if you are already in there. (I think mine was $3 at an auto parts store). If it is just the sensor (sure sounds like it) I would wait, and...

    Anyone permantely disabled park assist?

    My wife's 07 Denali has had park assist issues since we bought it used. I have fought with it to try to get it working, but now would rather not have it at all. We back right against our garage door when parked in our driveway and the beeping would wake up our toddlers if they were asleep in car...

    Sunroof leaks, drain tubes issues

    Preface: I have read all about the sunroof leaks and clogs etc I have put water through my drain holes manually and have figured out its my drivers side drain that is the issue. The passenger side gargles and gets rid of the water I manually pour in a hurry. The driver side does not. It does...

    Anyone fixes their own service park assist?

    I attempted to listen to each one with a mechanic stethascope, none of them made noise. Perhaps it has all of them shut down due to being a fault. I took the b pillar trim piece off also, with no luck, never did find any sign of worn wires, so now I am at a lost as to what is the issue. The...

    Anyone fixes their own service park assist?

    Yeah I may try that, I have changed the "faulty" sensor or what may be faulty with no luck. I also took the rear bumped skin off the other day to check wiring behind it between the sensors and saw nothing obvious inside the wiring loom and didn't see anything that would lead me to believe its a...

    Anyone fixes their own service park assist?

    Has anyone tackled the service park assist themselves? I have it on our 07 Yukon Denali. I have scanned the codes and it showed a short to voltage on the left most sensor. I tried to just replace that sensor with no luck. So I'm looking to dig In to it more. I have done a ton of research and it...

    Help me decifer this new to me Denali's autoride

    Mine seems to be an on going battle. Comp runs every two minutes, but is very loud. I can hear it over the idling 6.2 100' away... Hooked up the rv today, squatted the truck, comp fires up, but never lifted. Which is odd, because when messing with it previously I pulled an air line off and it...

    Dragging my feet to throw parts at it, oil pump? Relief valve?

    Honestly if I were to do it again, I would unbolt the front diff tube at the CV flanges and u joint and REMOVE the front diff, 12 more 13 or 15 mm bolts and a lot more room to work. Tools need were pretty basic. 10, 13, 15, 18 and I believe 24mm for steering rack. One swivel socket and basic...

    2009 Tahoe oil pressure failure

    Yeah, it could be, and its really easy to rule it out. Super common problem fro what ive read (and I've read a looot) From there check the o ring on the pickup tube going bottom of oil pump. I just dropped my oil pan to check this and had a cut completely through it. Also super brittle (as in...

    Dragging my feet to throw parts at it, oil pump? Relief valve?

    I'm super new to torque but where I found it was Settings-manage extra PID and selected the preloaded list that includes GM. Then manually enabled it and oil temp from there..

    Dragging my feet to throw parts at it, oil pump? Relief valve?

    At this point, no. I dropped the pan to replace the gasket, because it was leaking and decided to look at the O-ring first. I will see what this does and go from there.

    Dragging my feet to throw parts at it, oil pump? Relief valve?

    So I don't have it all back together yet to verify but I only dropped pan at this point.... And How did I have any oil pressure at all? What you can't see is the o ring is super flat and brittle, when I took it off I broke it into pieces supppper easy...

    2009 Tahoe oil pressure failure

    First pull out the sending unit on the back of intaje manifold. It's a bit of a ***** but there is YouTube videos on it. Then pull out the tiny little filter under it, replace it, $4 at auto parts store. If you can, check with manual gauge, if not, I'd replace the sending unit (I'm battling oil...

    Passenger side axle shaft seal

    Gonna have to go get a or Chilton but it appears I have to drop and split the diff to get the shaft out. I took out the bolts at the flange as well as at the diff like video showed. I can't get it to split apart fully. I can get it to pop at the diff but doesn't come out completely. There must...

    Passenger side axle shaft seal

    I am in the process (couple minutes each night after work) to drop and replace my wife's oil pan gasket on her 07 denali. While I am in there and have half of the front axle drooping to replace the pan I am wanting to fix her other leak, a passenger side axle shaft seal. I have never done one of...

    2007 GMC Denali stalls after towing

    I had this exact same happen on a different vehicle (still GM though) and it was the crankshaft position sensor. It would get hot, screw up, and tell the computer the crank wasnt spinning so it shut down the fuel injectors. After it cooled down, it fired up and ran fine. At least thats where I...
