Since the first automobiles, there have been radiators. Every liquid-cooled engine on the road has, and has always needed, a radiator; without it, the engine would overheat in no time, causing catastrophic engine failure.

The heads on your commercial or fleet diesel are one of the most integral parts of your engine. The heads are comprised of the valvetrain, exhaust ports, intake ports, and injector ports.
