2001 Saab 9-5 Water Leak

check your heater bypass valve ,located to the back of engine tie straped to wire harness on firewall ,it is a black valve with hoses connected to it ,valve can be had alone cheaper ,if it is coming from throttle body there r only 2 water hoses connected to it ,but the only thing that leak in that area for a 9-5 is the heater bypass valve ,check that and get back to us ,if this info helped tell us thank that will let us know that u looked back .
