    Can I swap 2nd row bench for captains in 2012 XL Denali

    Did you find a vehicle yet? I have the tan interior and want a Bench for the second row. Depending where you’re at I’d be down to trade.

    NEED 2nd row power folding bench. I have Captains.

    Ok I have an ‘09 Yukon XL Denali with heated, power folding 2nd row captains. I need to swap to the same style 2nd row heated, power folding bench. I have a tan leather interior. Any leads or trades would be appreciated. I’m in the DFW area.

    Wow if we are only moving 1300cfm total then a cooling fan upgrade may be one of the best upgrades yet. @Geotrash i nominate you to change your before the Yellowstone trip lol

    Keeping coolant and transmission temps under control when towing in the summer heat

    So with how mine is mounted it’s far enough back that slapping a rodent or two wouldn’t damage it. The one thing I haven’t done is wrap my long tubes and cross pipe. You can see I paid the price for that a few posts ago. I just love the way headers looked unwrapped but I may need to let that go...

    Keeping coolant and transmission temps under control when towing in the summer heat

    So for a tuner you need to find a local tuner who uses HP Tuners and can change your cooling fan parameters. I am not sure what exactly you mean by the higher wattage fan. Did you buy new fans or is one of your not working correctly?? Also I’m still not following the restriction question. Are...

    Also I thought I blew her up yesterday driving up to Genesee park to return the trailer. On the steepest part we got a flashing check engine light and started losing power quickly. I was able to make it to the side of the road and checked codes. Found cylinder 4 misfire and cleared it. I started...

    Keeping coolant and transmission temps under control when towing in the summer heat

    That’s good news brother!! I’ve been MIA due to no cell coverage and spotty internet. First since you saw temps in your trans around 260 before I’d recommend doing a fluid change. Most ATF breakdown over 240. So I definitely need to do baffles. If I choose to keep this as my tow pig I will also...

    Keeping coolant and transmission temps under control when towing in the summer heat

    Sweet man. I am looking forward to hearing about your trip. Not much has changed here. I did fill back up with 91 with 10% ethanol and now I don’t see smoke. I had to remind myself that the ethanol was added to help vehicle burn cleaner and since the last tank was non ethanol and I don’t have...

    Keeping coolant and transmission temps under control when towing in the summer heat

    Lol right!! Seriously though it was great. Our first three nights are at The Virginian RV Park in Jackson. The Monday we head to Colter bay for 2 nights, then Buffalo fireside or something like that for two night and then Grant campground for 4 nights. the only time I’ve been unhappy with my...

    Keeping coolant and transmission temps under control when towing in the summer heat

    Alright so today went much better. 1st there was no wind!! Yay!!!!! Second the road was nice and gradual the whole way to Jackson. Trans temps never went above 200 and the coolant never saw over 215. I held 4 gear almost the whole way and sometimes ran in 5th. 3rd was necessary for a few long...

    That’s great. So the biggest difference is we are all aluminum block and heads in the 6.2 whereas the Tahoe has the 5.3 which is an iron block. The iron block takes a long time to heat up compared to the all aluminum setup we have.

    Keeping coolant and transmission temps under control when towing in the summer heat

    Oh nice. Yeah I worked up here a lot when I was with UPRR. I checked the oil cooler lines and the fluid was not consistent with engine oil. It felt like power steering fluid or what I’d assume was shock fluid. I’m gunna take the rig through a do it yourself car wash and get it all cleaned off...

    Keeping coolant and transmission temps under control when towing in the summer heat

    Alright, well we made it to Rock Springs. It was a brutal trip. Roads were torn up in places and we had wind gusts up to 60MPH (gotta love WY) and a sustained wind of 25MPH. I can for sure say the Denali does not like thin non dense air, and hot air (it was 83-90 all day till dusk). Pulling the...

    Ok for some reason Tapatalk won’t log me in. So how about a first day report? We went from East of Dallas to North Denver in a day. 14 hrs with stops. Saw a best of 11.5 MPGs. This little trailer is all steel. Frame, panels and inside framing as well. It’s a fairly stout and heavy little guy...

    I’ve been saying this for awhile now. I am tuned and had my fans changed to be more aggressive at lower temps. I am really curious to see how it does this trip. Sent from my iPhone using Tapatalk

    I just bent mine back to contour the bumper. It doesn’t hang any lower than the bumper valance. Sent from my iPhone using Tapatalk

    Keeping coolant and transmission temps under control when towing in the summer heat

    Great information. Have you thought about moving your license plate down like I did on mine? That alone will allow much more airflow. Since installing my new cooler I haven’t seen the trans get higher than 187. I haven’t towed anything yet though. We leave in less than 48 hrs. for Yellowstone so...
