2007 Toyota Yaris Parts Questions & Experts Answers

• Q: How to service and repair the water pump on 2007 Toyota Yaris?

  A: Service and repair of the water pump starts with disconnecting the negative battery cable and draining the engine coolant. Begin the water pump service by first removing the engine under cover RH and the fan and generator V belt along with the generator assembly and engine mounting insulator sub-assembly RH. Special Service Tool: 09960-10010 (09962-01000, 09963-00700) will be needed for holding the pump while you disconnect its 3 mounting bolts. The third step involves taking out the water pump assembly through the combination of 3 bolts and 2 nuts together with the gasket. At the drainage opening of the water pump assembly look for coolant leakage and check the pulley operates without noise and smooth turning while replacing the assembly if needed. The water pump assembly requires installation with the new gasket positioned under the 3 bolts and 2 nuts while torquing channels to 11 N m (112 kgf cm, 8.1 ft. lbf). Use Special Service Tool: 09960-10010 (09962-01000, 09963-00700) to hold the installed water pump pulley with 3 bolts until they reach a torque of 15 N m (153 kgf cm, 11 ft. lbf). The work sequence begins by installing the engine mounting insulator sub-assembly RH for both hatchback and sedan then continues with the generator assembly and fan as well as generator V belt installation before adjusting the belt. The procedure includes checking the fan and generator V belt before reattaching the cable to the negative battery terminal with 5.4 N m (55 kgf cm, 48 in. lbf) torque. Engine coolant should be added and a leak check is performed before under cover RH engine installation.
