Confusing Radiator Part Numbers
I need a new radiator for my 2008 base coupe, z51, manual transmission. I have had two GM parts dealers tell me, based on my VIN number, that the GM part number I need is 10353890, or ACDelco part 21540. If I look at the parts catalog for Cultrag, it shows three different radiators, one of them with the 10353890 part number. However, the description in the catalog for that part number says "w/o oil cooler, auto trans." One of those three radiators has the description "w/o oil cooler, manual trans." Did something change in model years where the auto trans and manual trans radiators are used interchangeably? I want to believe that, using the VIN, as both of these vendors did, would yield the correct replacement part, but I am confused by the description not matching my car. Any help is appreciated.

Z51 cars with the a6 do not have external oil coolers but do use the bigger radiator that the z51 manual and Z06 share. If you have a manual car that does not have an external oil cooler then you do not have the bigger radiator(non-z51 cars). Engine oil cooler is not in the radiator but in front of it in 08(if you have the z06 or Manual z51)
Again A6 z51 uses the same part number larger radiator as the manual z51 and Z06 (10353890).
