  Q: How to service and repair the heater core on Scion xB?

  A: Service and repair operations on the heater core start with taking apart the heater radiator assembly. The first step involves removing the air duct assembly through detaching its 4 claw connections. The first step to remove the heater cover involves removing the screw then unhooking the 2 claws. Detaching the claw enables thermistor assembly removal which includes clamp removal before you pull out the thermistor. Unscrew the 4 screws securing the heater radiator unit sub-assembly while disconnecting the No. 2 cooler wiring, then remove the screw and bracket, detach the clamp, disconnect the connector to extract the heater radiator unit. The reassembly process starts by fitting the heater radiator unit sub-assembly followed by clamp connector attachment and screwing in the bracket while using the four screws to fix the No. 2 cooler wiring. You should install the thermistor first followed by the application of clamp and claw afterward. The heater cover requires attachment with two claws followed by screwing in the fastener to secure it. The installation of the air duct assembly requires the attachment of its 4 claws.
