    6.0 Cold Start Snorting

    2005 Yukon Denali with ~200,000 miles on the 6.0. I'm not driving this truck as much anymore, so when I start it, she's dead cold. I get a big "snort" sound on startup, almost like a piston is pushing air back out the intake. It goes away after the engine is running, but I'm wondering if it...

    Looking for a diesel 4x4 'burb. What to look for??

    I have an '05 Denali that I love around town, but my wife and I are looking to move further out of town. Now we are looking for a snow truck (possibly a plow) and long distance hauler, and was considering a 1999 or older diesel 'burb for the job. What should I look for when interviewing...

    2005 Denali Yukon won't take fuel- NOT THE EVAP SOLENOID

    I have a 2005 Yukon Denali AWD. It won't fuel more than at a sipping pace. It takes about 45 minutes to fill up the entire tank. First, I disconnected the filler tube and ran a piece of bungee through with no issues. Then I came to this forum and discovered the Evap solenoid is a regular...

    Front Hub Squeeka-squeeka Question

    2005 Denali with AWD, 180,000 miles, well maintained. I have a "squeeka squeeka" sound from the drivers front wheel when turned to the left. It started out minimal and only on hard turns, but now is doing it on even slight turns. Thought it might be the squeal bands on the front pads, but...

    DRL to LED Conversion- Won't light up???

    I have replaced almost all the incancescnet bulbs on my 2005 Yukon Denali with LED's from superbrightleds.com. I put cool white replacement 3157's in the DRL spot, but they won't come on. Opinions? At first I thought I just had the bulbs in backwards (LED's matter), but they still won't...

    2005 Denali CD Player Replacement Cubby?

    I upgraded my head unit, which doesn't speak the GMC lingo, so my old factory in-dash 6 disc CD changer was useless. I wanted to swap out the factory CD player for a cubby to store cell phones and such. I ordered Genuine GM 15958735 Instrument Panel Cluster Compartment . This part is about an...

    What to do with old factory head unit and CD player?

    My factory head unit is on her last legs, but the dash multi-disc CD player worked fine until I changed head units last week. Anyone know someone looking for one? I'm just going to pull it and put the cubby in place.

    In WAAAAY over my head. Trying to install new head unit

    2005 Yukon Denali, with the Bose stereo system. Basically, the CD player in my factory head unit and the 6-disc changer both took a crap and I ordered a new head unit. I thought if I ordered the "kits" needed, it would be basically plug and play- it isn't. Now I have a $600 rats nest, with no...

    Welding on Frame Precautions

    I'm getting ready to weld a small tab (LED backup light) on the trailer hitch with a stick welder. Normally I pull whatever component I'm welding off the vehicle and do it on the bench; this will be the first time I've ever welded on the vehicle itself. I still could, but pulling the whole...

    Instrument Panel Lightbulb Replacement (LED Conversion)

    I have a 2005 Yukon Denali, 160,000 miles. One of the lights behind the gauge pod is going out. So far I've been able to tap on the dash and it will come back on, but that will only work for so long. I've got to pull the dash soon anyways, and was going to address this issue while I was back...

    Third Brake Light Burnout Rate

    My 2005 Denali, w/ 160,000 miles. I've replaced my center/third brake light about 3 times in the last two years. They aren't particularly expensive, but they aren't cheap either (~$60 a pop on amazon). I've noticed that other Yukons of this ilk also seem to have a constantly burnt out third...

    Exterior Temp Gauge WAAAAAYY Off (too hot).

    2005 Yukon Denali, 160,000 miles. My exterior temperature gauge in the center rear view mirror is way wrong. Says it's 95, it is actually 68. Said it was 141 the other day, it was actually about 95. Anyone know where the sensor for this is?

    The elusive steering wheel light fuse

    I've read the tech write up on the steering wheel fuse, and still can't find it. I took my whole dash apart, found a brown and white wire, with no inline fuse anywhere under the dash, certainly not within 4" of the BCM. I also checked between the clock spring and steering wheel. Opinions on...

    Found the Rear Blower Problem, now what to do about it?

    So after buying a new resistor, figuring out that wasn't the problem and volt checking everything, I finally pulled apart the connector next to the emergency brake. It is burned and damaged inside both connectors of the plug. Is there a way to replace the entire plug, or should I just wire...

    How to: Upgrade fog lights and install LED lightbar

    This is a tech write-up for my own question, and is how to upgrade the fog lights and install an LED lightbar, so they automatically come on depending on which factory light (Hi or Lo) is being selected by the driver. I ordered a set of PIAA 510 Crystal Ion fog lights from Amazon and a CREE...

    Fog Lights on Low; LED lightbar on Hi (automatically)

    The wifey drives a Subaru, and I recently upgraded her fog lights in the factory position to a pair of Crystal Ion PIAA 520 fog lights. They throw more light than the highbeams (Subaru has an easy fix to keep the fog lights on with the high beams). So now I'm all jealous. I have an 05...

    Electronic Suspension Control Module for sale

    I got the dreaded "service ride control" message. On the advice of a mechanic, I purchased the electronic suspension control module for my 05 Yukon Denali. When that didn't fix it, he recommended the dealer, who easily diagnosed the torn airbags. I put in the Arnott system, and all is well in...

    The end to a perfect day

    Awesome day. Managed to piss off my boss, girlfriend, and random librarian. Come home to find a kid riding a dirt bike in my suburban front lawn. Pulling into the garage (tight squeeze) and crunched the passenger side mirror. Fantastic. Is there anything I should know before ordering...

    New Arnott Air Suspension System Questions

    Working on my 2005 AWD Denali, with about 130,000 miles on it. About a year ago I got the dreaded "service ride control" message and noted that the left rear air bag was torn. I just replaced all 4 shocks and the compressor with the Arnott system, with a new dryer (more on that later)...

    Diagnosis of Bad Fuel Level Sender Unit

    My fuel gauge is doing the usual symptom of hanging around the 1/4 full or empty mark. The fuel light still seems to be accurate, and the fuel gauge crawls up after about 20 minutes of driving. I have read other posts that indicate it is either the step-motor in the gauge or the sending unit...

    Slightly Upgraded Brakes

    Working with an 2005 Yukon Denali AWD, 130,000. I have to replace the rear pads because they are low on material. The front rotors have a slight shimmy, so I was going to replace those and the pads as well. I just put all 4 new tires on the beast and even though I really didn't need 4 tires...

    To all the Naysayers out there

    I have had my 05 Denali now for 8 years, it just ticked over 130,000 miles, and the only real work I have done to it is the drivers air damper/actuator. We just got back from a ten day trip whitewater trip, and this truck pulled trailers down dirt roads like a champ, and made the 22-hour drive...

    Transmission gets Mercon III or VI? What about the transfer case?

    I'm confused. 2005 Yukon Denali, AWD with 110,000 miles on it. I am trying to do the transmission flush, as per ScottyBoy's write up. Seems pretty straight forward, and in his writeup he uses Mercon IV (6). Did the vehicle come with Mercon 3, and he is upgrading to 6, or has it had...

    Larger oil filter

    Not to open the huge can of worms, but I read one post about putting a larger oil filter on the 6.0 L. It sure looks like a larger filter was supposed to go there all along. I generally stick with AC Delco for my GM stuff. Anyone got the larger AC Delco filter number handy?
