HAS ANYONE HEARD THE FAN UNDER THE HOOD, ALWAYS TURN ON FOR A FEW SECONDS?
i don't own an IS, YET, but if the 2j motor is like the 7m, which i am pretty sure it is, then the fan will automatically start up with the motor, until its clutch moderates it. the clutch in the fan controls its speed by using the rotational inertia it creates. kinda like how a seat belt works, it only is supposed to lock up when it is pulled fast, and the rotational inertia pulls out pins to lock the sprockets inside.
