If you checked everything that was suggested and still have problems, an electric puller fan will solve your dilemma.... I added an a/c condenser and trans cooler to the front of my fresh 4 row radiator and had the same problem til I went with the electric unit. Now it can idle all day in hot weather with the a/c running, no worries... I think Wes sells a unit made for these trucks...??
