Damaged during transportation. Please check the photos for better understanding.
Even the lower part of the radiator (heat transfer area with copper tubes and epoxy coated aluminium fins) look undamaged, there is a big risk due the twisting/bending of the whole radiator, that there might be damaged tubes or preliminary damage, which can become as leakage later at site. Even after pressure test, there is no 100% certainity, that leakages could come later on due to maybe as small crack already occured now, but not leaking in test at factory.
Many details show that the hit has been strong and whole radiator has changed the shape.
All casing materials are destroyed and can not be repaired.
In practice, all fan units including fan collar, fan motor, fan impeller, motor brackets, fan guard etc. have suffered minor or manor damage. All motors should be tested for bearing damages all other materials should be completely replaced with new ones to ensure vibration free operation.
Being sold "AS IS, WHERE IS". Buyer is responsible for shipping and handling.

These units of Damaged Radiators were involved in an insurance claim and are being sold by the insurance company to recover funds from loss.
Conclusion based on visible inspection:
Radiators has suffered such major impact, that even the new pressure test would not take away the risk for leakages at site. Even after the successfull leakage test at factory, the unit might start not to leak at site due to further transportation and after few heat expansion.
The manufacturing method for such radiator is, that the copper tubes are mechanically expanded to the aliminium fins and aluminium supporting plates. They cannot be anympre removed from each other after the expansion in the factory.
The attachment points (around 2000 pieces) of thin-walled copper and aluminium supporting plates are the most critical for later leakages. Strong hit against these attachments points change the joints and cause increased stress during the thousands of heat expansion at the life time of this engine cooling heat exchanger.
There is no method to check; if heat transfer tubes have damaged that slightly and that the will occur later in use. After this type of damage the full guarantee is not valid anymore.
Even the radiator heat transfer area could be saved, the damages on all other parts of radiator are so serious, that the only repairing method would be replacing them with new parts. The upper casing materials as well as the fan units would need to replaced with new parts. Even small changes for example in the fan collar shape or fam impeller, can cause vibrations to the total fan unit and this type of vibration will lead to bearing damage in the fan motor.
The estimated working hours for one complete new radiator are around 100 hours. Dismantling of existing parts would require additional 30-40 hours as minimum and further damages could be found during the dismantling of the radiator. This type of work can be only done in the original manufacturing site at Finland.
