Unfortunately for us, the aluminum radiator is about 1⁄2-inch thicker across the core than the three-core copper/brass we had before. Couple that with the larger fan clutch, and it was Interference City. We can’t blame the radiator, however, as it was intended to install with a triple electric fan setup. We went without the fans for this story, as we are planning to dyno the truck before and after to see if we pick up any ponies by going all-electric. We had to tweak one of the A/C lines to get the big radiator to fit, but then had to relocate the upper post-mount-holes about 1-inch forward so that the radiator cleared the fan clutch. We were able to re-use the factory lower radiator mounts. The fan shrouds need to be trimmed at the upper and lower edges to fit the radiator. Once we got it installed, we could push the truck as hard as we wanted in the hottest weather (up to 120 degrees near Death Valley, California), and it never got out of our comfort zone or anywhere near the red.
