Fuel Gauge Inaccurate - SOLVED
Update: After two full fill ups, the gas gauge reading is close if not at the standard reading. I have nothing to attribute this to. I have monitored the distance and gallons used, then on fill up (all the way) it corresponds with what actually was used and the gauge needle seems to be back to... -
Fuel Gauge Inaccurate - SOLVED
Here is what I have discovered so far. Today 2/18, I checked the signal circuit at connector 152 (under the fuse box, eng comp). I pinned into the signal circuit (purple) and low reference circuit (black). Using my DMM, read Ohms. I have two meters so checked both on each test to verify. To... -
Fuel Gauge Inaccurate - SOLVED
I see when I posted the charts, they flipped. So the one I stated as first is the dirty looking one (GMC Fuel level#2), whereas mine is the clear white one that says Fuel Level Specs. -
Fuel Gauge Inaccurate - SOLVED
I have a conflict. A chart copied from this forum (first one) shows just the exact opposite volts and ohms readings for the entire range most notably Full and Empty. The second chart is from my OEM shop service manuals for 2004 (Yes, I have all three). Is it possible the first one is from an... -
Fuel Gauge Inaccurate - SOLVED
Similar to what MassHoe04 posted (in the link) the values for everybody's enjoyment (attached fuel level specs). I have all the factory manuals to follow and refer to but sometimes this forum has experienced shortcuts. Would a Kent Moore J33431C signal generator be any help? Looks like I'll do... -
Fuel Gauge Inaccurate - SOLVED
It looks like the access to the ohm wire is at the instrument cluster 24 pin connector. Using the Service Manual it says that wire would be B7-yellow wire. I'll try my Ohm reader on that wire and see what the values are. If I had a signal generator I could make the gauge move and see but so far... -
Fuel Gauge Inaccurate - SOLVED
Greetings. I have a 2004 Yukon Denali @260K+ miles. My issue today is fuel gauge malfunction. According to mileage and previous economy(?), its off 1/4 to 1/3 depending on actual. Up until last week it was or seemed accurate, but Saturday was reading under 1/4 tank and I filled it with 13.2... -
Blend Door Actuators - Tonight
I did this on my 2004. I used a process from Sparky's answers online. I think I saved the process on a USB drive if anyone wants to see. I took the dash off and there are a few tips and tricks that were useful plus a layered process that made reassembly easy. It was more like 6-8 hours incl lunch. -
Front and Rear Control Arms & Polyurethane Bushings
Great write up with mostly exacting details. 5 stars for removing the (front) upper and lower bushings whereas most comment to just get new control arms which you did however could be applied to those (like me) wanting to use my original control arms and install new bushings. I have a question...- oldchev

TPMS Sensors
I have a 2004. Apparently this was a first year? or special that was different than other years that followed. The difference is the stem or the stem seal. I was doing tires at Costco and their brand TPMS didnt cover that year. I was able to discover that Schrader makes the OEM TPMS valve most... -
Any tips for better mpg
I have an 04 Denali Yukon. My suggestions are keep tires inflated to the maximum range or 32-34 psi, then review your driving technique. People may hate your slow starts and timing the lights and on freeway stay at 65 or ... 70 if allowed. The faster you go, creates more drag. I know, Its very...- oldchev

Complete Dash Removal
Sparky's Answers has a still picture step by step on this for replacing the actuators way deep inside. Most of the dash is removed especially the color change parts you are talking about. There are some tips for removing some of the more difficult items, like the grab bar. For me it was a below... -
Wheel Bearing?
I think I would jack up that side and see if its loose or makes sounds, or feels rough. Take the wheel off and rotate it. See what it is like. I have a 2004 Denali and I get and have been getting Service Stability notifications for several years. They are sometimes accompanied by the traction...- oldchev

Grease guns
Mine leaks too. I used a metal tray and a some old towel to help soak and contain the oil. Seems nothing can be done to stop this. Greasing although essential, is a messy proposition. That article says: "If a cartridge tube is left in a grease gun, the grease gun should be depressurized, wiped... -
2002 Tahoe..Help with rotational whirring.
Maybe I missed this, but has the noise grown gradually worse over time? Yes, new or rebuilt replacement parts can be bad but not likely right from the start. Hubs a year ago no change, another (rebuilt?) front diff, new axles, no help...to me its a rotational sound not u joints, sounds like a...- oldchev

Wet Concrete From Transmission Extension Housing
Late jumping onto this thread. This is a great forum. Lots of very intelligent, thoughtful, helpful individuals trying to diagnose and fix a problem based on sometimes limited information. Hard to do. The oil mark seems considerable so more than a light drip, more like a seep and it been going...- oldchev

Hot New LS Prototype From GM, Especially For You Turbo Guys
BMW developed this type of engine and was/is a Hot V set up. The BMW N63 engine yielded 445hp on the V8 550i. The earliest versions had lots of problems. The arrangement causes high concentration of heat emission. There the turbine oil lines also pass. As a result, the tubes get coked and the...- oldchev

Sunroof track arms have snapped - any experience with a fix?
I thought about reposting this as a new thread with a different header for interest however I'll see where this goes. I contacted Paul at Gruven Parts (www.gruvenparts.com). He said he could fabricate a new pair of arms out of steel or aluminum but needs written commitment for about 20 sets. I... -
Sunroof track arms have snapped - any experience with a fix?
I just found this from "Gary in Texas" on another post. I don't know how long the repair lasted but he posted in 2018. Quote: "I know this is an old string but I had the same issue with my 2006 Avalanche...both broke out of the blue. What I did was drill the rivet out, took some shrink wrap... -
Sunroof track arms have snapped - any experience with a fix?
Thanks adventurenali92... Greg from TG emailed me back and said they don't carry that part (slide arms). So I'm interested in knowing what parts you have with the kit. He said most customers just remove the deflector. I have looked at both sides and they broke in the same spot. I imagine the... -
Sunroof track arms have snapped - any experience with a fix?
2004 GMC Yukon Denali. Me Too! Damn sunroof deflector track guide problem. Both side guide arms now broken. I can close it if I watch my fingers and pull the air deflector down when closing. I see the parts at TG Automotive (not clearly) and they say "Sunroof assembly must be removed from... -

2008 Tahoe-What to look for
If it were me and I was remotely interested in this vehicle and he called me with the reduced offer, I would have countered immediately with your bottom line. That said, I don't think you'll ever be happy with this car. Walk away, keep looking for one that you think has what you want, check it...- oldchev

Coolant leaking from transmission cooler line
My 2004 Yukon has had coolant leaks at these points twice. I believe the o ring responsible is inside the tank. After looking at the tank securement I felt the chances of further leaks elsewhere where too great and considering the work doing r and r of radiator was enough to just warrant a new...- oldchev
