I have the original radiator in my 5 speed 1LE and noticed it does not have a auto trans cooler. Thought that was neat, so show your tanks stickers on factory stick radiators.

1991 LB9 1LE here, same exact tag except date code (mine's 05 ie May).

Thanks Time2Fly, interesting. Maybe Chaz will show us a pic of his ultra nice stick Conv IROC 5 speed radiator tag. Right now this stuff may not appear important but I believe that it will be more important as the value of our cars increases.

Photobucket is down. But both my '89, 5 speed, hardtop and '89, 5 speed, convertible both have the same stickers but with different date codes.

Now I've got to go check mine.

Y'all have aluminum/plastic radiators from the factory? My '92 RS and my '89 Formula (both 5-speed, V8 cars) had copper radiators.

those would be replacement radiators-last year for copper in thirdgens would be '82,certain '82s also had the aluminum radiators.In some other GM models,have seen copper up to ~1987.

From my '89 hardtop. Date coded 5/89. Car was assembled 5/89.


From my '89 convertible. Date coded 11/88. Car was assembled 12/88.

Really neat Chazman, consistent use of part number for at least 3 years!
