learning the 3.1 radiator for the 93 Lumina Euro

[kegunder23]

Hi,

I'm looking for a new (or used hopefully) radiator for my 93 Lumina Euro sedan 3.1L and I can't fully understand what all the options are. My car is a 4sp Auto w/ AC. (Its the "T" model, identified by the 8th VIN digit)

I see options for an oil coooler, transmisstion cooler (driver and passenger side), and 1' or 1 3/8' core thickness. I can see a metal tube that screws into the side of the radiator near the filler neck. I can't exactly tell what is all coming in and out of the radiator at the bottom of it.

Do all of those radiator options correspond to specific model features?

What other years share the same part as mine? (91-93?) I'm hoping to find a used one on eBay before my JB Welded coupler fix stops working

Thanks very much.
