I need to spec a radiator for a diesel powered centrifugal pump. The engine is a 665 hp series 60 Detroit running at 88% load and it overheats in the hot summer sun. We can just get a radiator that measures the same size as the one from a truck with the same engine but my boss would like to get the right radiator for the job rather than just guess.
I have looked and not found a way to determine the size of a radiator in BTU per minute. Any suggestions?
