Aaron, I'm not afraid to ask the dumb question!
Are you sure your motor is overheating and it's not just your temp guage playing up? Or maybe you're just too anxious about it. You say you can touch the radiator while this is happening. This does not sound like an overheating motor to me.
My 190E will run up to about 110 when the fans kick in and it cools down. Been doing that since I bought it 50k ago and no overheating probs at all. I might worry if the guage went into the red on a regular basis but otherwise I stay cool, just like my motor
