Default Radiator Part NOs

I want to order a new radiator from rockauto.com

I looked through many of the threads on here, but some of them are from years ago and the availability of part nos have changed.

I have a 2005 z51 manual coupe. I am having trouble figuring out which one to order as the z51 has the oil and trans cooler option, and the website has awful pictures which do not show if it has the proper fittings for this setup.

any help would be greatly appreciated!

The pictures on RockAuto are pretty clear to me, and unfortunately none of them (I checked 2005 and 2009 Corvette) show any oil cooling ports on the driver side. You will need to find another source for a radiator to fit your Z51 w/oil cooling.

Personally I would go with the CSF radiator which has the option for trans and engine oil cooling so it's universal and offers better cooling over the stock radiator.
