white serial number question

[uncle scat]

I have white 2-85 serial number 285102-408 , going to need new radiator, aftermarket parts catalogs have serial number break at297446, guessing I have one before the break ,any input would be appreciated. PS, I've owned tractor for 26 years . Thanks

   Serial number 297 447 and later tractors had the Dot 4 engine, thus the radiator was changed at the same time.   You need the earlier radiator.
