Acutally, it's there to "help" regulate a little valve to feed more air into the intake while idling to induce a slightly lean condition to help heat up the car more. Once the coolant going through there is warm enough that valve will close. Ever notice how you start your car on cold days and the idle is higher then normal? And your foot is not even on the pedal? Well this is true for the honda's so I figure it might be similar to 240's.
