have you tried usung radiator leak stopper

Luger Redd

Never use stop leak!! It clogs up the heater core and corrodes the aluminium inlets and outlets!! Which to answer your question is what probably why you still have a leak the bottom inlet/outlet has probably corroded (like mine)! Its literally over top the front passenger tire! Take the tire off and remove the wheel well covering and there should be two hoses running to aluminium inlet/outlets one or both of those probably corroded and broken off!
