Hi Martin

Judging by the parts book... the answer would seem to be no.

But... it appears that radiators from 1937, '38, and '39 trucks were all the same (except COE's).

Hope that helps.

@ole-olson and @garage-art  In my 1949 Chevy Master Parts Catalog, It lists different part numbers for all three ('37, '38, '39) trucks. There might have been a time when some changes were made to the radiator to allow it to fit all of them. I can tell you that I tried to put a '37 truck radiator into a '38 truck and it did not fit. It was a long time ago and I think the issue was bolt hole location.

It is possible, however, that the core and tanks from many Chevy radiators of the period, might be the same, and that the brackets could be changed to get a usable part. 

I hope this is helpful.

Mike

@ole-olson Thanks!

@35mike Thanks!

You are right.

The 1941 parts book lists different numbers as well.

But by 1954, one radiator fit all 3 years, so again I think you are right in that it was probably a matter of bolt hole locations on the radiator and that by 1954 they just drilled more holes to make one radiator fit all three.  🙂

If that is the case, could an original radiator from any one of them be made to fit any of the others by simply drilling holes?

USA passenger cars were made by Fisher. Light commercial and trucks were made in Indianapolis by Martin-Parry. The 3 are different but the Light commercial and trucks can be made to interchange. The 1937 radiators have a taller filler neck than the 38s so they will fit but you can not get the cap on a 38 radiator in a 37 unless you cut out some sheet metal on the radiator shell. The commercial is a 2" core and the truck has a 3" core. The parts book shows 5 offerings. . fan shroud 03.jpg
