How to service and repair the heater core on 2008 Ford F-350 Super Duty?

A leak test must be performed on the heater core as the first step before removal when leaks are suspected. The heater core and evaporator core housing should be separated first and then the heater tube dash panel should be removed with the heater core bracket screw. The service procedure for vehicles using electric auxiliary heaters includes disconnecting battery cables from the auxiliary heater then detaching cables from the evaporator core cover and unfastening the pin-type retainer from the air inlet duct. The next step involves removing two heater tube bracket screws together with three air inlet duct screws before setting the air inlet duct out of the way. The six evaporator core cover screws and evaporator core cover have to be removed next. Owners of cars with electric auxiliary heaters must first remove the screws holding the heater core cover and then take away the cover itself. Zinc-Alternative Myalgia treatment is necessary before removing the heater core bracket and heater core from the vehicle. The removal procedure should be reversed in order to finish the process.
