Actually, I think you are talking about the two lines that coolant passes through on the throttle body. These are for quicker warm ups in cooler weather. Buy yourself some caps at the auto parts store and cap them off....that way you'll have the cheap thottle body coolant bypass mod that a lot of guys run.
