Leaking antifreeze my 2001 jeep grand cherokee is leaking antifreeze and also underneath around the muffler area where the passenger door is located?

First, remember that any leak will run down...There is nothing near your muffler that contains antifreeze, therefore, what ever is leaking has been blown back there while driving. Open up the hood and look to see where leak is originating. check all hoses, hose connections, radiator, rug under heater in the cab and everything associated with cooling system. You will see antifreeze coming out somewhere. Once you locate the leak, I can help you deal with it. Do not open the radiator when engine is hot! Do not drive with low coolant condition! This is not a solution...yet...I'ts the beginning of one!
