2011 4.8 Radiator Upgrade

[STLMODROPTINE]

Hello all,

 

I have a 2011 4.8 with a 4 speed. I've read some threads about the temp guage going above 210. Mine is doing that when I'm sitting at idle for a few minutes, and most recently towing in the mountains. Does anyone know if the 5.3 radiator is bigger, and would it fit my truck? I hate seeing my temps climb. Or does anyone know if the fans can be programmed to come on sooner?

Instead of changing out the radiator, I'd replace the fan with dual electronic fans that you can set the running temps.
