New Radiator Summer Coolant Temps

Hi All,

As promised, I would provide infomation on how the new Macs radiator performed in Summer temps. I took the coach to Borrego Springs over the weekend. Daytime temps were in the high 90's and Sunday it was 100 in the shade. On the way back to San Diego, I had to climb Montezuma Grade, a continuous climb out of the desert for 15 miles averaging 6 to 7% inclination around many twisties and hairpins. It loaded the Cummins up pretty good.

And the answer is: 214 degrees. I am more than satisfied with the new radiator.
