B73 or 75 radiator

Recommended Posts

Have two here but I am not 100% sure if they are OEM.

One is out of Cummins truck (B73) with a core thickness of 2.75", 4 rows of 1/2" tubes in a staggered pattern with 10 fins per inch.

The one out of the B75 is 2.375" thick with the remaining specs same as above.

It doesn't cost anything to pay attention.

                             Thanks for the reply, the one that was in it was 3/4 tube 4 row 3.00 thick. But in talking to the builder in B.C. those 3/4 tube radiators flowed to fast. and the coolant would not cool down enough exiting the bottom tank.

                             Years ago they built 1/2" tube five row for Cummins powered loggers. Thanks again.

One ping only
