    2011 Denali Suspension

    Well I have it working again. I thought I would post the resolution in case it might help others out there in the future. So I went through and tested the 3 fuses that I found references to for the suspension system and they all tested good. I then located the relay for the system and with the...

    Aux Transmission Cooler

    Yeah this is kind of my thinking. The one I am looking at has it. I suspect this might be why the one that the OEM uses is not all that big.

    Aux Transmission Cooler

    Are you concerned at all about hitting minimum transmission temps? The person that sent me the link to the Trucool 40k is reporting the same that he doesn't see temps over 150. However he didn't think installing the bypass was worth it. His truck (07 Suburban) didn't have the OEM aux cooler so...

    08 Denali body molding tape?

    Once you do one, the other three are pretty quick. I always have a few rolls of that tape because I use it for other things so I just did all 4 of mine. The biggest time saver was masking around them on the door before starting so I could quickly slap them back up there and move on to the next...

    Aux Transmission Cooler

    Yeah, the point is that 210 on a hot summer day I am fine with as well. However I was seeing 210 at 73F or so means that when it is 90+ it probably won't be at 210 anymore. Filter and fluid changed about 40K ago and getting ready to do it again. This is why I am considering addressing this...

    Aux Transmission Cooler

    Yeah that is the same aux cooler that I have on mine. I was just expecting temps a bit lower than 210 being air temps (low 70s) were not that hot out. I wouldn't think much of it if we were in July with air temps in the high 90s. I guess the good side is that with the OEM aux cooler the lines...

    08 Denali body molding tape?

    I used this when I did mine a while back. https://www.amazon.com/3M-03614-Scotch-Mount-Molding-Tape/dp/B002JOVUO0/ As others said. Make sure to clean off the old tape first which is a long process. I also placed blue painter's tape on the door before removing them to mark the location. I could...

    Aux Transmission Cooler

    I have a 2011 Denali and it has the KNP (Cooling, auxiliary external transmission oil cooler). I think it might be standard on Denali trim level trucks. Anyhow we bought a new camper this spring and went out on our first trip this past weekend. I normally keep an eye on transmission temps while...

    2011 Denali Suspension

    I have a 2011 Denali with the air suspension. Last year we had a rear shock fail. It wasn't a leak but rather a sensor or check valve failed. It wasn't a case where the compressor was running constantly though. I only knew about the issue because I had the Service Suspension message in the DIC...

    Running Hot In Snow

    Yeah we do clean it off when stopping but when on a road trip, I don't want to stop all the time. It is different if just running around town. I was just wondering if the Denali grill being flat with holes is more prone to icing up. While that could be cleaned, there was no cleaning the snow...

    Running Hot In Snow

    Last Thursday night we were driving to Milwaukee for a wedding. It started out as rain but at around midnight it transitioned to sleet and then snow. None of the roads were being plowed and we were in lots of semi traffic. Eventually snow started dropping off the semi in front of us as it built...

    Dead Battery overnight..

    Check your trailer plug. Pin 4 on the 7 pin trailer connectors is a run to the battery. Not sure on these trucks as I haven't checked mine yet but in the GMT800 series they would save a buck by not putting the 40 Amp Fuse in the fuse block that is needed to activate this. I found this out when...

    No auto with hood open

    I haven't looked for the sensor but if you don't see a pin switch and such, then it likely is in the hood release latch mechanism.

    Memory seat,heated steering wheel & mirror issues on 2007 tahoe LTZ

    - Memory seats - Can you go through the information center and see if seat position recall is enabled? I think it can be set to on/off. This is the case with my 2011 Denali. - Heated Steering Wheel - While you have the button for one, I do not know of a Chevy LTZ that has a heated steering...

    Looking to buy

    Not sure off the top of my head. I know the 20s on mine are OEM because it is the Denali which comes with the Chromed Aluminum 20s stock or 22 as an option. Junk yard is a possibility. Try checking Craigslist. You may find someone upgrading OEM rims and want to offload them. eBay may be another...
