what is the short, wide radiator for in the center of the lower bumper. I thought it was a secondary heat exchanger for intercoolers but it does not go there. seems to go deep under the engine. where does it go?

On the S430 I own, it is the evaporator or condenser (I can't remember which) for the AC system. Look to see where the hoses run. If they run to the AC compressor, that's it. If they run to the engine or transmission, it's a cooler for that.

For the S600 it is the oil cooler, here is a pic and the OC is #110 in the diagram.

Take care and enjoy the ride,
Greg

thanks, oil cooler i guess. I wanted to add a larger heat exchanger for intercoolers in its place but i guess the oil cooler is needed.
