Small radiator infront of main radiator???

2012 prostar with maxxforce 13. I have a coolant leak that someone tried to patch at one point.

It is coming from a small what looks like 2 peice radiator that mounts in front of the main radiator and behind the inter cooler. It looks like there is an upper and lower unit.

Does anyone have the actual name or part number for this?

Thanks

 

No its coolant. A/c condenser mounts to the front side of the intercooler. A good distance from this

 

Thanks that makes sense. It looks like a 2 peice unit. The top line comes out of the egr cooler the lower line goes to the small heat exchanger for the low pressure turbo. The section is low behind the bumper. I'll see if I can find it with that info
