I think it's stock. I'm not sure there's an internal one in the radiator. Doesn't the crossover land at the very edge on top of the drivers side?
No oil cooler lines?

You can see the lines go right past the radiator to the oil cooler mounted in front.

The tall, skinny cooler on the drivers side looks suspiciously like the power steering coolers I robbed off of GMT 800 Suburbans and are now residing on my two GMT 400 pickups........?
Hmmmmm...

I stand corrected. Now I remember what that thing was even though I only found out through @Tonyrodz. I remember thinking it was an oil cooler at one time. Man Im getting old, losing my memory.

One giveway is trans and power steering coolers will have 3/8" lines, while engine oil lines will be 1/2". At least on the GM trucks...........
I never really paid attention to it other than it was almost in the way of my intercooler I was installing. I wanted my Whipple installed!
it is, engine cooler is in main radiator on the driver side, radiator with engine cooler is about 1" thicker.

We need a memory wing up in here. Also, we should have a memory wing.

Yup.
Deleted it for now until I install the new aftermarket one I have.
I just looped the hoses.
Jeez get with it already!

I'll get there.
No rush, just wait for something else to go bad in this area. You kill two birds with one stone

I hope not. I'd rather work on it for fun, not because something broke. That sux.

Wow, looks like the cooler itself was leaking. I've never seen or heard of that. Usually it is the cooler lines that begin leaking at the hard line to flex hose union. Of course, GM made the cooler and lines all one unit. I cut out the flex hose in mine, flared the hard lines and replaced the flex portion with braided lines.
well just imagine if mine main radiator goes bad, wonder what's going to happen when trans fluid engine coolant and engine oil mixed together?

I've seen alot of them leak the same as mine. I'm in NJ, so maybe has something to do with our salty winters.
