Yea its probably coolant then,which sucks all things considered. Now I just need to figure out if the car came with an oil cooler by default so I can order the right radiator.
I don't see any line ports on the driver's side.

IIRC, all models have engine oil cooler lines, but not all have transmission cooler lines.

Nope! I was wrong. You don't have the EOC lines on yours. I just went out and looked at mine because it backed up to my walkout basement doors, and like 20 feet away from where I work.

You can see the EOC lines connected through that plate that's bolted to the side of the oil pan, and if you look rearward you can also see the transmission oil cooler lines routing down/under the AT to the passenger side.

And here is where your EOC lines would connect to the radiator, if you had them.

And, hiliariously enough, double-checking the EOC lines routing helped me find a missing socket!!! Look down on the engine mount perch.

What I find even funnier about this whole thing is I called the local Chevy dealership where I got the car from YEARS ago, gave them my vin and everything, and they said it had both the engine and transmission cooler lines. Oh boy, I sure do love getting two completely different ,answers but he,y that's why we check the radiator first before ordering parts

If it were me, I'd retrofit the EOC & TOC lines with a radiator that has provisions for them.

Now I'm curious. If you don't have the EOC installed, then what does your oil pan look like where they normally mount?

There's a block off cover that connects the two oil ports.

I think all radiators have the trans cooler ports, but not necessarily the engine cooler.

it doesn't matter if the radiator has or doesn't have a oil cooler in your case, the oil cooler would just not be utilized the oil cooler section is closed off from the rest of the system.
the oil cooler is just in the plastic end cap if it is not used it just sits there as empty space. Doesn't affect anything.
