Yes, I believe (although I haven't seen it yet) a separate heat exchanger under the front lower grill. Since you don't have Air Conditioning anymore... I'd use the space taken normally by the condenser to mount a monster intercooler heat exchanger (like you see on the Mitsubishi Evos).

Looked like a small separate pump to me, but it also looks like it's hooked into the coolant overflow reservoir too... I'd have to do some more digging.

Cheers!
