These are some bolt-on or bolt together diesel semi truck radiators that came in for repair and rebuilds. The radiators with a hole in the core are for Autocar garbage disposal trucks. The hole in the radiator core is referred to as a crankhole which is for the PTO driveshaft that passes through the radiator to power the hydraulic pump which is mounted out near the front bumper.
