Hey guys, I just had my car towed to the dealership to have them install the new radiator and new cooling fan. I ordered new OEM parts from Rock Auto, and the replacement radiator is missing a fitting for the aux coolers (from what they're thinking). I have pictures of the problem area on the new radiator and what it looks like on the old radiator, and also the part numbers. If anyone could help me, I'd even be willing to pay you $20 if you can answer why my new radiator is missing a fitting and what to do about it! The dealership thought I ordered the wrong part (understandably) but it's OEM, it is the same part number they'd order, and if you look at the line drawing, it doesn't have a fitting in the picture! I am stressed. Ugh. I was really hoping to have my car back today.

New Radiator part number: 84947856
Old Radiator part number: 23343094

My car needs the radiator with optional V18 cooling part number: 23477182 or 84947855

Ugh, what a nightmare. But apparently they have it in a warehouse and will get it installed tomorrow.

RockAuto shows *84947855*, not 56, as your radiator. It specifically says “with auxiliary coolers” so I’d guess you just got the wrong radiator from RockAuto? But the RockAuto listing looks correct to me. 855 is also listed for my ‘17 2SS so I think they’ve got it right.

Yep that's exactly what happened. I assumed it was the right radiator since it listed the 6.2L V8, I didn't realize our cars could be optioned differently (besides the LT1 trim that came later.)
