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

  A: Installation of the 1NZ-FXE engine timing chain requires starting with the No. 1 cylinder at 20 degrees ATDC while placing the crankshaft between 40 to 140 degrees ATDC and synchronizing the intake and exhaust camshaft sprockets at 20 degrees Machine ATDC to 20 before resetting the crankshaft to 20. ATDC. The ATDC shows 20 degrees while positioning the crankshaft between 40 to 140 degrees ATDC must be achieved. The technician first positions the No. 1 cylinder to 20° ATDC and places both the crankshaft between 40 to 140° ATDC and all camshafts at 20° ATDC before resetting the crankshaft crank angle to 20° ATDC. ATDC before resetting the crankshaft to 20 degrees ATDC. You must use 2 bolts at 9.0 Nm (92 kgf-cm, 80 in-lbf) torque to install the chain vibration damper before correctly aligning the camshaft timing sprocket marks with the timing chain yellow plates and camshaft timing gear and crankshaft timing sprocket marks followed by chain tensioner slipper bolt installation at the same torque value. The chain tensioner installation requires users to first raise the stopper plate, unlock and push in the plunger, lower the stopper plate while locking the plunger before inserting a 3.0 mm (0.118 in.) diameter bar through the stopper plate hole while securing it with 2 bolts at 9.0 Nm (92 kgf-cm, 80 in-lbf). Put in order the oil pump seal, timing chain cover and crankshaft position sensor along with the camshaft timing oil control valve assembly after checking for proper tension between the intake and exhaust camshaft timing sprockets. The first step involves installing the engine mounting bracket through 4 bolts at 55 Nm (561 kgf-cm, 41 ft-lbf). Then proceed with the engine mounting spacer installation at 2 bolts sharing the same torque value followed by the engine mounting insulator RH with 3 bolts and 4 nuts at 52 Nm (530 kgf-cm, 38 ft-lbf). When installing the crankshaft pulley position the crankshaft damper's hole onto the straight pin then mount the crankshaft damper while using Special Service Tools: 09213-58013 91111-50845 to tighten the crankshaft bolt to 128 Nm (1,305 kgf-cm, 95 ft-lbf). Ensure the tool does not hinder the chain cover during installation. Install the water pump followed by the drive belt while performing a tension check of the drive belt. Screw the purge VSV while applying Toyota Genuine Seal Packing Black or Three Bond 1207B or equivalent onto seal packing and within 3 minutes before tightening all 9 bolts and 2 nuts to 10 Nm (102 kgf-cm, 74 in-lbf). Install the ignition coil together with brake master cylinder reservoir cover and wire harness followed by windshield washer jar and reservoir bracket and brake master cylinder reservoir and No. 2 air cleaner inlet and air cleaner assembly with all connections properly secured. The installation sequence includes placement of the front cowl top panel outer followed by the windshield wiper motor and wiper link assembly and cowl top ventilator louvers and hood to cowl top seal and front wiper arms with wiper arm head caps before engine oil addition along with negative battery terminal connection and lastly installing the rear floor boards. Check for leaks during the final installation phase before you close the radiator support opening with its cover along with engine under covers and front wheels. Initialization steps need to be done after reconnecting the battery.
