How to service the heater core on Ford Focus?

Draining the engine coolant must be the first step toward servicing the heater core. Detach the glove compartment with its three screws before removing it. Reinstall this component at a torque of 10 Nm (89 lb-in). Begin by cutting the heater core tube cover using a utility knife along the existing rib before disconnecting the climate control wire harness connector on the cover and unfastening the two screws. Start by placing a drain pan underneath the heater core area before unclipping the two tube connections with their O-ring seals which need to be discarded. Institution of the heater core access door involves detaching it and then removing the housing while carefully moving the heater core. The installation of the new heater core requires competent placement of fresh O-rings followed by proper tube seating before connection clips are used to secure the assembly. Seal the heater core tube cover cut with suitable black duct-type tape followed by engine coolant level filling.

The Heater Core in Ford Focus vehicles is very essential in offering the warmth it needs in the cabin through the residual heat from the engine. Similar to a smaller car radiator, the core is cooled with a combination of water and antifreeze and the ultimate material can be aluminum or brass among others. The features of temperature controls can be different, for example, some of them can have an electromechanical actuator to set desired temperatures. In the air-conditioned automobiles, the heater core is also instrumental in dehumidification since it reheats the cooled air. Some problems are the blockage, drip and rust, and majority of them may involve dismantling of the dashboard. Further, it is possible to apply other types, methodologies in Air-Cooled Engines but this will pose some danger.
