THE RADIATOR HAS 3 SECTIONS - PASS-SIDE (TRANNY COOLER), CENTER (REGULAR RADIATOR) & DRIVER-SIDE (CRANKCASE OIL COOLER). THE CRANKCASE COOLER HAS AN OPENING AT THE TOP & AT THE BOTTOM. WHICH OF THE 2 DOES THE "RETURN OIL" LINE CONNECT TO? TOP OR BOTTOM?

I have a '92 Suburban w/towing package. I'm installing a auxiliary crankcase oil cooler in front of the radiator. The radiator has 3 sections - pass-side (tranny cooler), center (regular radiator) & driver-side (crankcase oil cooler). The crankcase cooler has an opening at the top & at the bottom. Which of the 2 does the "return oil" line connect to? Top or Bottom?

Billymac,
Thanks for the super quick reply.
Your answer matches with a reply I received from another source.
So, I guess 2 matching replies makes it a correct response.
Once again, thanks a bunch.
