This is a radiator module we rebuilt for a Komatsu 930E-5 haul truck. The radiator is a MESABI which utilizes aluminum tubes, or cores. The radiator was leaking due to a cracked tube. External fouling with dirt & rocks was substantial within the tubes & fins of the lower section of the radiator. We replaced several tubes as well as all the upper & lower rubber grommet seals. All the tubes we reinstalled were cleaned & flushed internally & externally during our reconditioning process. After our full premium rebuilding procedure to the radiator a final pressure test was done to ensure the dual radiator assembly is leak free & ready for another round of service.Motor Mission Machine and Radiator(702) 649-2366 or (702) 649-0648
