The laws of thermodynamics certainly allow one part of the system to be at a different temperature. Bear in mind that this is not a steady state system - the amount of energy enetring the coolant from the engine is constantly varying, as is the amount of heat lost at the radiator. Just because the coolant at the sensor occasionally peaks at 85C doesn't mean that the coolant in the reservoir would ever reach that temperature. -- Grunff
