• Q: How to replace the water pump assembly on 2004 Scion xB?

  A: The first step for water pump assembly replacement requires draining engine coolant while removing engine under cover RH. Start by removing the fan and generator V belt before proceeding to take off the engine mounting insulator sub-assy RH. Apply Special Service Tool: 09960-10010 (09962-01000, 09963-00600) to keep the pump pulley stationary and remove the 3 mounting bolts before the pulley. Remove the water pump assembly by unfastening its three bolts along with two nuts until you can detach the water pump from the gasket. The new water pump assembly must include the gasket when installing through the 3 bolts along with 2 nuts while torquing to 11 Nm (112 kgf-cm, 8.1 ft. lbs.). Reinstall the water pump pulley through the utilization of Special Service Tool: 09960-10010 (09962-01000, 09963-00600) and tighten the 3 bolts to 15 Nm (153 kgf-cm, 11 ft. lbs.). After reinstalling the engine mounting insulator sub-assy RH, it is necessary to install the fan and generator V belt with a temporary placement of the V-ribbed belt on each pulley. Readjust the fan plus generator V belt before inspecting the drive belt deflection and tension. Refit the right-hand engine under cover after securing its bolt and nut with a torque of 5.0 Nm (51 kgf-cm, 44 in. lbs.). Complete the process by adding coolant to the engine before inspecting for any fluid leakage.
