What does the radiator area consist of?

If the radiator was a sandwich, and the outside grill was one slice of bread and the transmission cooler (a larger canister) was the other slice, what sits between?
There is a radiator, a CAC, hydraulic fans and I don't see anything else.
Am I missing anything?
I assume that the radiator on the opposite side of the motorhome is for cooling the fuel, engine oil or maybe the A/C.

I am trying to fix a hydraulic leak (looks like clean oil) and have replaced one of the fan motors two months ago and am in the process of replacing the second. I just want to see if there are any other suspects prior to reassembling it all and refilling with fluids.

On my coach there is a hydraulic cooler between CAC and the radiator. The fan on the
left side of the coach is the condenser fan for the AC.

oooh, I was afraid of that. I would imagine that it would a bear to get to and may explain the leak.

I have no problem writing a check to get it fixed right, but I just can't get a local mechanic that touches these things. It looks like I'll be digging harder.

If you remove the belting under the radiator and the CAC you will be able to see it.

I'll do that next. Maybe I'll get lucky and just have to tighten a hose. Anyone want to place bets?
The radiator was replaced last October at a Cummins shop. I am really hoping that they forgot to tighten a connection and that connection is within reach. I am sick at the prospect of yanking out that heavy radiator just to fix the cooler leak.

On my 1996 U320, outside to inside: louvered panel, fuel oil cooler, radiator, charge air cooler. The transmission oil cooler is a water cooled tube bundle to the right of the engine, looking forward.

I had mine worked on br Steward Stevenson in Longview TX. They work on heavy equipment and worked in my exhaust manafold when Foretravel would not do the job. They discovered my Charged air cooler was split and did that also.

Doubled the power of my new to me coach.
