Ford E-150 Problem
Average Mileage: 102,500 mi (52,000 mi - 154,000 mi)
Electrolysis can cause repeated failures of the heater core and radiator. The diagnosing technician should check for voltage present in the coolant, with the battery disconnected, because electrical current in the coolant causes electrolysis. Corroded or deteriorated parts should be replaced, and the coolant should be flushed. Ground straps can be added to help prevent future corrosion of components.

Water, antifreeze is leaking out when i drive. When i stop steam is coming from the rear passenger side behind the tire somewhere. I have to put in 3 gallons of water every 8 miles or so.Over heats. But my 1990 E150 van starts right up even on the coldest days.
