Ford E-150 Problems

Coolant Leakage from Heater Core, Possible Leakage onto Passenger Side Foot Well on Ford E-150

Problem Description and Possible Solution

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.
