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

  A: The water pump replacement procedure starts with draining the engine coolant before removing the engine under cover RH then the fan and generator V belt. The engine mounting insulator sub-assy RH and water pump pulley require Special Service Tool: 09960-10010 (09962-01000, 09963-00600) to remove the 3 bolts at their respective locations. The next step is to detach the water pump assembly by unfastening 3 bolts and 2 nuts then removing the water pump while separating it from the gasket. To install the components first position the new gasket and water pump using the 3 bolts and 2 nuts while implementing a torque of 11 Nm (112 kgf-cm, 8.1 ft. lbs.). Use Special Service Tool: 09960-10010 (09962-01000, 09963-00600) to install the water pump pulley by fastening its 3 bolts with a torque of 15 Nm (153 kgf-cm, 11 ft. lbs.). The next step involves reinstalling the engine mounting insulator sub-assy RH as well as the fan and generator V belt but the V-ribbed belt should be initially placed on each pulley. Adjust the V belt on the fan and generator followed by an examination of Drive Belt tension and deflection before reinstalling the right-hand engine under cover while tightening the bolt and nut to 5.0 Nm (51 kgf-cm, 44 inch lbs.). To complete the procedure you must add engine coolant before checking for any fluid leakages.
