"UN" BB Camaro radiator application?

**tom406** · #1 09-22-2001, 04:47 PM

Just yanked the fine-working but incorrect big block Camaro radiator out of our Z/28. It has a "UN" tag that I can't find in my reference materials. Can anyone help me identify the year and application? Thanks!

69 Camaro 396ci/375hp with auto trans.

Thank you sir. Mind if I ask your source?

I checked it again today, and there's no provision for auto trans cooling lines....

I stand corrected. UN is for a 396/375 w/manual trans. UO 396/375 w/TH400. ZE - 396/375 w/TH400. ZD - 396/375 w/manual trans. My source is observation of different cars and comparing finds with other Camaro folks. As far as I know, there is no factory ID info on these codes

. UN & ZD are for same app., but why different tags? Maybe a production/engineering change at some point. I am interested to know what is the two letter embossed raised code, stamped on the the right side tank of your radiator just below the "fill" line?

Those letters would be an "O" and an "L". Thanks again for the info. If anybody needs this radiator, let me know, we should be able to work a deal (I don't think I'll be getting a 375HP 396 car in the near future, but you never know

)
