I have a 1997 ford expedition and its a 2 wheel drive with a 4.6 engine. My proble is that water is leaking and I believe its the radiator, and I have to keep putting water. Then in the inside of the expedition the windshield gets foggy and I believe its the water that is being evaporated. My qhuestion is what can I do to fix it and why is this problem occuring? This is the third time this happens usually we just take it to the mechanis and they fix it but after a year it starts again.
