Had my radiator out for pressure check, clean and paint. The tag reads WT 337 under that is 0501 D
I have no idea what that all emeans. Anyone have any ideas? :waving:

see other post I sent.

OR it's a application ID number for the manufacturer of your radiator.

WT stands for Wolverine/Trentrade a manufacturer out of buisness now.
the 337 is the DPI part number for that radiator
DPI is the standard part numbering system for aftermarket radiators

was the tag not on the radiator when you sent it in ?

Jim, Thanks for making thist post..I pulled mine to do the drivetrain swap, and wound up buying a new radiator. But looking at the original one, I see that I have a series of #'s too and didn't know what they mean...If you're doing the rad., you must be close to painting everything and getting ol' Thunder back on the road! :beers: Good luck with everything!

The tag was on the rad when I took it in, its still on there, see in the pic above, bottom right edge of it almost looks like a smudge. Thanks for the info. guys.
