Chris, when you say "fans", I'm assuming you have the pusher. In traffic, it may need to be "tweaked" to come on a bit sooner than where you have it set right now. It was designed to help in just this driving condition. There is very little air flow across the radiator core when in stop-and-go traffic, speeds less than the 35mph main fan setting, and most of all.... when running at low speed with a tail wind where the under hood temps climb and the thought is that the radiator is not doing its job, or the fans are at fault.
It May be time for one of Mikes coolant tune up kits. We have been running our trucks in Phoenix 110-115deg with stock rad. Shut off to shop and come out to restart and the temp is showing over 135 immediately. Butt Pucker ??? Sure !! just get moving and let the fans take over. We could All Use the Kit, as the cooling system has been neglected for what, 13-16 years Because it has Not been a problem until Now. Huh...?
I do Not think a Bigger radiator is the cure for you .
Take care, Bro...
