• Q: How to remove the water pump assembly on 2009 Toyota Sienna?

  A: The first step to remove the water pump assembly from the 2GR-FE engine requires disassembling the engine assembly with transaxle. The worker should start by securing the engine followed by removing the generator assembly before removing the compressor and magnetic clutch. Begin by removing the front bracket of No. 1 engine on the left-hand engine mounting. The workshop must remove the No. 2 idler pulley sub-assembly when they extract two bolts and two idler pulley cover plates and two No. 2 idler pulley sub-assemblies. It is essential to note that the idler pulley cover plate measures 33.6 mm (1.32 in.) and the No. 2 idler pulley cover plate measures 37.8 mm (1.49 in.). The V-ribbed belt tensioner assembly requires removal after taking out its five bolts. Special Service Tools 09960-10010, 09962-01000, 09963-00700 enable you to maintain control of the water pump pulley before you extract its 4 bolts and pulley from the system. The water inlet housing can be dismounted first before taking out two bolts and a nut and housing assembly with its gasket and O-ring of the water outlet pipe. To conclude the water pump assembly removal procedure you must disconnect the 16 bolts, remove the assembly, along with the water pump gasket.
