  Q: How to remove and replace the radiator on Scion xB?

  A:

  The process of removing the radiator starts by emptying all materials from the refrigeration system. Begin by removing the No. 1 radiator grille garnish and then proceed with removing the radiator grille before extracting the front bumper cover. The engine coolant drainage completes first before disassembling the battery terminals and removing the battery carrier bolt along with the nut for extraction and finally removing the battery insulator and battery plus the battery tray. To separate the No. 1 water hose clamp bracket users must disconnect both water hoses while removing its two bolts. The hood lock control cable assembly can be detached by unfastening it from the hood lock through clamp disengagement. The hood lock support sub-assembly needs removal after disconnecting both honey connectors and removing the two bolts. One should first disengage the heated oxygen sensor wire harness clamp before disconnecting the inlet radiator hose then proceeding to disconnect the outlet radiator hose. The service procedure starts by extracting the two radiator support cushions from the No. 2 fan shroud. Then separate the two fan motor connectors and remove the two bolts which allow complete extraction of the No. 2 fan shroud. The discharge hose sub-assembly and air conditioning tube and accessory assembly need to be separated before removing the condenser. The radiator assembly removal process begins with disconnecting the No. 1 water by-pass hose from the radiator followed by electric conduit access to independent racks of the automatic transaxle cooling system. Finish the operation by first removing the two lower radiator supports followed by separated clamp removal of the fan shroud and extracting both inlet and outlet radiator hoses from the radiator. Then take out the two bolts to complete the fan shroud removal.

  Q: How to install the radiator on Scion xB?

  A:

  The installation of the radiator begins with fan shroud attachment utilizing two bolts that need torquing to 7.0 Nm (71 kgf-cm, 62 in-lbf). Begin by attaching the outlet radiator hose while installing the inlet radiator hose with proper placement of the hose clamp on the fan shroud. Mount the 2 radiator supports to the radiator afterward and position the radiator on your vehicle while connecting its Automatic Transaxle oil cooler hoses. Use 2 bolts to fasten the No. 2 fan shroud before torquing to 7.0 Nm (71 kgf-cm, 62 in-lbf) and connect the 2 fan motor connectors. The 2 radiator support cushions should be installed onto the No. 2 fan shroud before connecting outlet and inlet radiator hoses followed by securing the heated oxygen sensor wire harness clamp. Fasten the hood lock support using 4 bolts while torquing them to achieve 13 Nm (127 kgf-cm, 9 ft-lbf). Then secure the 2 hone connectors. The hood lock control cable should be installed according to the diagram while clamping onto the hood lock support. The No. 1 water hose clamp bracket needs installation along with 2 bolts which should be torqued at 5.0 Nm (51 kgf-cm, 44 in-lbf) before connecting both water hoses. Start by placing the battery tray along with battery and insulator before fastening the battery carrier with a bolt that gets torqued to 17 Nm (168 kgf-cm, 12 ft-lbf) and a nut torqued to 3.5 Nm (35 kgf-cm, 31 in-lbf) and finally attach positive and negative terminals with a torque of 5.4 Nm (55 kgf-cm, 48 in-lbf). The procedure includes adding engine coolant followed by refrigerant charging and engine engine heat up and leak inspection for refrigerant and coolant.
