Does the Throttle Body have anything to do with a coolant leak?

throttle body" fuel", cooling system separate.

On a 3.8 engine the throttle body and upper plenum contain coolant. There is a gasket between them that could leak. More important the upper pleninum on the 3.8 engine often develops a leak near the EGR inlet which is in the area you are concerned with.
