Does my radiator have an engine oil cooler?

Hmm……my 08 Yukon looks to have an external oil cooler and external power steering cooler from the factory. Nothing is incorporated into the radiator, is this the tow package?
All factory installed engine oil & tranny atf coolers come and go from the radiator.

like @Geotrash said, if there are lines in/out of the passenger side of the radiator? those are for the ATF/tranny, and lines in/out of the driver side of the radiator? those are for engine oil.
What is the rpo code (glove box)?
My 07 Yukon has a ps cooler and a atf cooler in front of the rad and the rpo code is KNP and is okay for light duty towing. No engine oil cooler or lines connecting above the oil filter and to the driver side of the rad.

My '07 XL Denali is the same - no engine oil cooler from the factory. However, when I installed a new radiator in 2023, I bought a Denso that has the engine oil cooler in it, along with a set of cooler lines. When it's time to replace the driver side motor mount again, I will install the cooler lines because we still tow heavy with it sometimes.

To get them in there, you'll likely need to remove the driver's side engine mount, the steering shaft, and the heat shield on the exhaust manifold. At least that's what I had to do on my 2012 XL Denali and it made the job a lot easier. I used a block of wood on the oil pan with a jack underneath, working gently to raise the engine just enough to get the motor mount out of the way. The oil pan can handle the weight - it's structural.
Got it, so that appears to be the way. Motor mount and jack it up a bit with a wood block. Thanks!

Right now I've got the new radiator in and have the motor mount basically out, so I'll fiddle around some more this weekend and finish it up.
