When "big" power came out in the late 60s, early 70s, everybody was trying to put a bigger radiator, like Peterbilt 359 and Freightliner Powerliner, that had the grill almost to the headlights. In the late 90s and into the 2000s, we have real big power, and yet our radiators seem smaller. My 379 had a 470 Detroit, which is a lot more hp than a 335, and the grill is smaller than a 359. Yet it never ran warm. And forget about the Aero trucks, with the tiny radiators.
How are we cooling…
