I know why the coolant line is connected to the throttle body. I live in Arizona and definitely do not need it. Also do not need the extra heat in the engine. I know some have done it and looking at it seems very easy. I see the line on the right side going to the radiator tank, but I cant seem to see where there is anything coming out the other side?

Any directions or a small guide to do this procedure? I searched but nothing specific comes up.
