GM Yukon XL Denali Transmission Temps
My main tow vehicle is my RAM CTD, but when we take the RV as well the truck has to pull my 7000 pound boat. So then we use my 2011 Yukon XL Denali to tow the Malibu. It has always run hot - both...

Well, today was the day (yesterday now). Loaded everything up to use the Yukon to tow the LSV to Powell.
Three people and four dogs, and all our gear for 5 days at the lake. Didn’t have much room in the Yukon, put a lot of stuff in the boat.
Temp was low 90’s when i left home. Temps i have seen before.
Got on the highway and noticed the engine temperature was running a bit high right out of the gate. Took the first hill by Red Rocks, and it went way high. Couple miles up, and it got bad enough that I shut off the air conditioning. Engine cooled down a little. Inside temp warmed up a bunch.
Slowed down to about 30 MPH. Turned the air back on, and the engine temp went way up way fast. Before I knew it, there was a message on the dash warning about the temp and that the air was shut off. On the plus side, the transmission temp never got about 200*
Not a good way to start a 450 mile trip. So we turned around and headed home. Quickly emptied out that Yukon. I hooked the boat up to my truck, my wife took a dog and my nephew in the Jeep, and we left again.
Set us back by about two hours. But we got here.
When I had the auxiliary transmission cooler installed, I worried if the added size right in front of my radiator would create another problem. Well, it looks like I have my answer.
I’m tired of chasing problems with the Yukon. When I get home I will step up my search for a replacement.
