I see in the PET that there's one part number (996-106-131-50) for a radiator that appears to fit both sides of the Boxster; however, there are two alternate part numbers (996-106-131-51, and 996-106-132-51) that supposedly only fit the left and right sides, respectively.

Are there certain vehicles that only accept the left/right radiators while others take the universal fit versions?

Thanks!

If you have an "s" you have three. If a base boxster, two.

Here are pretty decent instructions for adding a third - which includes a description of the entire coolong system FYI.
