My concern with mounting it after the radiator would be that it would be very hard to adjust for the cooling effect of the radiator when blocked. I want the grill to open before the fan comes on. If I wait until the coolant goes through the radiator and cools somewhat (which will vary depending on a bunch of things) I'll have no idea what temperature to set the switch open temp to. I'd like my sensor to know the engine coolant temp as soon as the radiator fan sensor, not somewhere farther down the chain. It would seem that putting the sensor after the radiator would create too much fluctuation and lag (vs the radiator fan's temp sensor) than if it was put further upstream.
