Cooling fans commanded/overheating towing

[pokismoki]

HPtuners offers an upgrade for our trucks fan system, I'ts posted on the forum by the techs there.

Can you post it?

 

I am aware that we can edit the axis for the fan settings but not aware of an operating system change for better fan controls on E92 computers.

have you tried installing the larger radiator from the 6.2 or maxtow option?. 5.3 trucks has a puny v6 radiator that is impressive for it's size, but easily maxes out cooling capacity when towing. I will be upgrading soon. 

 

if you got a tuner , try installing the upgraded OS for the cooling system via HPtuners, it gives you more control over the fan temps, also try running a 160 stat for summer towing.

This truck is a 6.2 NHT max tow,it never got warm towing before.I have HP tuners,tuner set fans to come on early,im down to pulling grill and fans and cleaning intercooler condenser and Rad with air then water.
