2002 Jeep Liberty, Leaking water below motor. Checked to make sure just water. Thought it may be coolant but clear liquid. AC and Defrost were off and hadn't been used. Cant seem to find where its coming from. Also, doesn't seem to leak when driving or when immediately shut off. Starts to leak on start up and a short period of time after I shut off engine. Any thoughts on where it could be coming from or causes?
