• Q: How to remove the timing chain on 2009 Toyota Prius?

  A: The procedure for disassembly of the 1NZ-FXE timing chain begins by taking out the rear No. 2 floor board followed by removing the rear deck floor box and completing by removing the rear No. 3 floor board. The negative battery cable requires removal while waiting for at least 90 seconds to protect Air Bag activation. Begin the timing chain removal process by taking away the radiator support opening cover together with front wheels, No. 3 engine under cover, and No. 4 center engine under cover. Begin the wiper arm repair by draining engine coolant and engine oil before eliminating the wiper arm head cap and front wiper arms (LH and RH) and hood to cowl top seal along with both cowl top ventilator louvers (LH and RH). The windshield motor with wiper link assembly and front cowl top panel outer and air cleaner assembly can be removed after releasing the clamps and disconnecting the intake air flow meter connector and removing wire harness clamps. To proceed you must first disconnect the No. 2 air cleaner inlet then remove the brake master cylinder reservoir while taking out the reservoir bracket. The service technician will separate the windshield washer jar assembly through its removal procedure whilst using Special Service Tool: 09213-58013 91111-50845 to keep the crankshaft pulley secured during crankshaft bolt loosening. Padding with 2 to 3 threads of crankshaft bolt torque followed by use of tools 09950-50013 and 09951-05010 allows crankshaft damper removal and final crankshaft bolt extraction. A supported oil pan with a jack and wooden block allows technicians to remove the engine mounting insulator RH along with the engine mounting spacer and engine mounting bracket. The connector should be disconnected first and then the technicians must remove the camshaft timing oil control valve assembly and the crankshaft position sensor and timing chain cover. Install the washer to the crankshaft bolt and rotate the crankshaft clockwise to set No. 1 cylinder at TDC while removing the oil pump seal. The procedure to remove the No. 1 chain tensioner requires the following steps: Lift the stopper plate, unlock the plunger and push it in and then lower the stopper plate before locking the plunger. Insert a 3.0 mm (0.118 in.) diameter bar into the stopper plate hole before you can proceed with the removal of the chain tensioner and its slipper and the No. 1 chain vibration damper. The chain removal process should start by removing it from the machine.
