03 Denali getting warm when towing on HOT days

[wade]

6.0 Denali.

When towing a 19ft car trailer (flatbed) with a 2,000 car on it on 90+degree days.... my coolant temp gauge will start to creep over half way, around 220f or so.

I am towing in TOW mode.

Is there any solution?

Thats normal towing that much weight in that kinda heat. 210 is normal, so 220 isn't too much of an increase considering you're towing in that heat.

That's not bad at all, a solution would be electric fans!

With such a large engine, and large radiator, I figured it SHOULDNT move over the usual spot the needle sits at.

6.0l Nali... your prob also running AWD. That alone is a draw on the motor when towing.granted an Electric fan would prob help but that increase isnt something I would really worry about. The tranny temps if anything would be what I would watch.

Depending on his year denali he might have e-fans stock.

What year is your Denali?
