Travelguy2500,
 
As long as the weight of the trailer and cargo does not exceed 8100 pounds, you should not have a problem. Unfortunately I am unable to give feedback or advice on using the Denali to tow a 7300 pound trailer as i have not done so; however, Edmunds is a great resource to find people with this experience.
 
Thank you and have a wonderful weekend!

I was wondering if you could tell me the towing capacity of my 2008 Yukon SLT 5.3L V8 VIN#: 1GKFC13J38R159666 (no flex-fuel)
 
I have towed a 4800 lb travel trailer approx 100 miles (one way) and noticed that my Yukon usually has a temperature of 210 degrees (even when not towing). However, when I'm towing the TT, as soon as I start any kind of hill or grade I can watch the temperature increase. I also noticed that the Transmission temperature increases as well...up to 232 degrees. Once I started back down the hill or grade the temp quickly returns back to the 210 degree mark. According to the RPO code and owner's manual, I have 3.73 gears and a towing capacity of 7500 lbs. However, I have read several other articles that state I only have 6500 lb towing capacity. Was wondering if I should be concerned about the fluctuation in temperature or if this is to be expected.
Also, should I tow with the "trailer" button on or not?

davidvc,
 
I understand your concern; I wanted to confirm with you that per GM the maximum trailer weight for your vehicle is 7500 pounds. It is also important to take the Gross Combination Weight Rating into account - essentially, the combined weight of your vehicle, cargo inside the vehicle itself, and the weight of the trailer should not exceed 13,000 pounds.
 
The Tow/Haul mode on your Yukon adjusts transmission shifts while hauling, making them less frequent and more predictable. This can perhaps be very noticeable on downhill grades.
 
As far as the fluctuation in engine temperature, engine coolant at higher altitudes will boil at a lower temperature than at or near sea level. If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to engine overheating. I am not sure what altitude you are driving at, but thought that this might be useful to you.
 
I am going to ask our Technical Assistance Center about the fluctuation in engine temperature you mentioned, just to make sure you are within a healthy range and that this is normal. Once I hear back from them, I will be sure to relay this information to you.
Regards,
Sarah

#32 of 49 2007 Yukon Towing Capacity by aseniuk

Apr 24, 2012 (7:52 am)

My husband and I have been looking at buying a travel trailer. We could be towing it with a 2007 Yukon. When looking online for towing capacity it changes with each website we look at- some saying only 4500lbs and others saying up to 7200lbs.
 
Just wondering what is the maximum weight the 2007 Yukon can tow?

That's an exciting investment! If you were willing to send us the last 8 digits of your VIN, we'd be happy to look into this further. You can either put them here on the forum, or send an email to socialmediagm.com (include your question in the email as well so we will have a point of reference!).

The following is the response I heard back on the fluctuation in temperature question:
 
Please see excerpt from owners manual page 3-47:
 
“It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210°F (100°C) or less. If you are pulling a load
or going up hills, it is normal for the temperature to
fluctuate and approach the 250°F (122°C) mark. If the
gage reaches the 260°F (125°C) mark, it indicates
that the cooling system is working beyond its capacity.”
 
I hope this helps!

#35 of 49 My husband is in a panic!! by mamashack

May 18, 2012 (9:38 am)

We traded in our Ford Excursion and bought a 2011 GMC Yukon XL-SLE (i know.. big downgrade) anyhow, now my husband is in a panic thinking our Yukon XL wont tow our 25' boat. Boat weight is 4300lbs, with about a 1,500lb trailer - total tow weight is 5800lbs. He's afraid it's gonna be a total dog and not be able to pull the boat.. We also will have a full car - packed with kids and all their "kid crap". Should we be worried we've made the wrong choice?? Vin# 1GKS1HE07BR265482

Hello mamashack,
 
Given your VIN, I found the following. I know it is a lot of terminology, and I hope that I can communicate it clearly for you!
 
The Gross Vehicle Weight Rating (GVWR) for your specific vehicle is 7200 lbs. This is the maximum number of pounds a tow vehicle may weigh. Everything that contributes to the weight of the tow vehicle is featured in this rating, including the weight of the vehicle, driver and all passengers, fuel, payload, trailer tongue weight, hitch weight and all optional equipment. The GVWR is displayed on the driver’s door or door-lock pillar label of your vehicle.
 
The GCWR (Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment and conversions; the GCWR for the vehicle should not be exceeded) for your vehicle is 11,000 lbs and the maximum trailer weight per the owners manual is 5,500 lbs.
 
It looks as though the weight of your trailer and boat exceeds that of the recommended maximum trailer weight; as far as how this may affect your vehicle, I am unsure. It may be a good idea to speak with your dealership on this matter.
 
If we can look into anything further for you, please don't hesitate to contact us at socialmediagm.com
All the best,
Sarah

#37 of 49 2007 Denali Towing Temperature by meyermdaj

Jul 23, 2012 (10:22 am)

Towing my 7,500# boat this past weekend I noticed the digital readout of the transmission temperature climbed to 227 going up hill and would typically hover around 200 on the flats. Is this too high? Will the cars computer tell me when the transmission is too hot?
 
It's a 2007 Yukon Denali 6.2L AWD.
 
Any information would be great. Thanks, MM
