Probably a plant or vendor code. It shows up on all manner of Mopar radiators of the period. It's on mine.

Radiator date code is usually stamped into the side bracket...

Part number #2998945

According to the Chrysler chart, 2998945 is a radiator part number for 1970 Dart/Valiant, 22", 318 w/o AC or 340 w/ AC.



As said above, 18398 is probably the manufacturer code.
In 1971, this code is 20446. At least, it’s the code of my 71 radiator.
