Toyota Sienna Parts Questions & Answers

• Tire Pressure Sensor, Driver Side
  84746-AE010
  Q: How should the TPMS Sensor and transmitter be disposed of correctly on Toyota Sienna?

  A: A lithium battery powers the tire pressure warning valve and transmitter so proper disposal of both items becomes necessary. A screwdriver tip can be used to remove the rear cover of the tire pressure warning valve and transmitter device until the battery and resined base board become visible. Cut the 2 connecting terminals between the base board and battery while you remove it.
• Ignition Coil

  Q: How to install the ignition coil and spark plugs on Toyota Sienna?

  A: The installation of the 6 spark plugs for the 2GR-FE engine requires placing them in position and tightening them to 18 Nm (183 kgf-cm, 13 ft-lbf). Use the 6 bolts to install the 6 ignition coils while torquing them at 10 Nm (102 kgf-cm, 7 ft-lbf) and then fit the 6 ignition coil connectors. First install the No. 1 surge tank stay with 21 Nm (214 kgf-cm, 15 ft-lbf) torque on its specified bolt. Then implement 2 bolts, 2 clamps and a nut secured with 8.3 Nm (84 kgf-cm, 73 in-lbf). The technician should install the intake air surge tank assembly followed by the air cleaner cap sub-assembly before adding engine coolant. After cable connection to the negative terminal check for engine coolant leakage during inspection. Begin by putting in place the V-bank cover sub-assembly followed by the cowl top panel sub-assembly outer front and finally the No. 1 cowl top to cowl brace inner. You must install the windshield wiper motor along with its link assembly and then assemble the front wiper arm for LH and RH positions.
• Water Pump

  Q: How to install the water pump assembly on Toyota Sienna?

  A: Begin water pump installation by applying a fresh gasket onto the assembly followed by its installation with 16 bolts. Torque Bolt A to 21 Nm (214 kgf-cm, 15ft-lbf) and Bolts B and C to 11 Nm (112 kgf-cm, 8ft-lbf), while avoiding oil on Bolt A threads and replacing C bolts with new ones or implementing adhesive 1344. The approved adhesives include Toyota Genuine Adhesive 1344, Three Bond 1344, or an equivalent. Attach the water inlet housing with 2 bolts and a nut according to a torque of 10 Nm (102 kgf-cm, 7ft-lbf) while being careful to avoid damaging the O-ring during installation. Use Special Service Tools 09960-10010, 09962-01000 and 09963-00700 to hold the pulley before tightening its 4 bolts to 21 Nm (214 kgf-cm, 15ft-lbf). Start by installing 5 bolts into the V-ribbed belt tensioner assembly and torque them to 43 Nm (438 kgf-cm, 32ft-lbf), then proceed with installing 2 idler pulley cover plates and 2 No. 2 idler pulley cover plates and 2 No. 2 idler pulley sub-assemblies using 2 bolts which reach 54 Nm (550 kgf-cm, 40ft-lbf) torque. Remember the diameter measurements of 33.6 mm (1.32 in.) for the idler pulley cover plate and 37 First mount the No. 1 engine front bracket LH to the front of the engine and place the generator assembly as well as the compressor and magnetic clutch units before adding the engine hangers. After removing the engine stand install the engine assembly and transaxle. The last task involves adding coolant before conducting a leak inspection of the system.
• Alternator
  27060-0A110-84
  Q: How to remove and install the alternator assembly on Toyota Sienna?

  A: The start by taking off the wire harness clamp followed by disconnected generator connector to remove the generator assembly. Open the terminal cap to extract the nut and the generator wire prior to loosening bolts A and B. Afterward loosen bolt C to decrease No. 1 V belt strain and then uninstall bolts A, B and the generator. Bind the generator by installing bolts A and B as an initial step before adjusting the No. 1 V belt tension by screwing bolt C until bolts A reach 58 N.m torque (592 kgf.cm, 43 ft.lbf) and bolts B achieve 18 N.m torque (184 kgf.cm, 13 ft.lbf). You should start by installing the generator wire along with its nut before torquing it to 9.8 N.m (100 kgf.cm, 7 ft.lbf). Then connect the generator connector while also installing the wire harness clamp. An inspection of the drive belt becomes necessary after completing the installation process.
