How to Service and Repair a Heater Core on 2003 Ford E-250?

Before servicing the heater core technicians must drain engine cooling system fluid then disconnect ground battery cable. After disconnecting the quick disconnect heater hose couplings at the heater core you should use suitable 5/8-inch or 3/4-inch plugs to seal the heater water hoses. First step is to remove both the engine cover and instrument panel finish panel. It is necessary to pull out seven screws which remove the heater core cover and discard the heater core case seal. After heater core extraction users must prevent coolant spills from any leftover coolant. Proceed with heater core installation by turning the removal process in reverse order while applying Merpol(R) meeting Ford specification ESE-M99B144-B or plain water as hose lubricant.
