1990 ZR1 Radiator - ZR-1 Net Registry Forums

FI250 · 11-21-2013

I recently purchased a 1990 ZR1 and found out that it has a replacement all aluminum radiator which will not pass NCRS Judging. I have found a new radiator for sale that they say is correct for all 1984 - 1990 Corvettes. my question is, does the ZR1 use a unique radiator? The GM part number for the radiator for sale is #52453612 and the Delco number is #20461.

Thanks
