• Q: How to install the timing chain on 2008 Toyota Matrix?

  A: A proper installation process for the 1ZZ-FE timing chain requires users to set the No. 1 cylinder at TDC/compression by aligning camshaft timing gear marks while using a crankshaft pulley bolt to set the timing gear key to the oil pump point mark. Utilize Special Service Tool: 09223-22010 to properly install the crankshaft timing gear while positioning its key point with the fitting yellow mark facing the timing mark. Begin the installation of the chain onto camshaft timing gears by placing the yellow mark links straight against their timing fixtures. The chain tensioner slipper requires installation with a bolt mounted at 18.5 Nm (189 kgf-cm, 14 ft-lbf) torque before attaching the "F" marked crankshaft position sensor plate to face forward. A light coat of multi-purpose grease covers a new oil seal lip before using Special Service Tool: 09223-22010 to tap the oil seal into the timing chain cover until it reaches its edge while inspecting for foreign objects on the lip. Fill the timing chain cover cave with a continuous seal packing string (3.5 to 4.5 mm diameter) after you remove old packing materials from the surface. Install the cover with 10 bolts and 2 nuts while torquing Bolt A and nut A to 13 Nm (133 kgf-cm, 10 ft-lbf) and Bolt B to 18.5 Nm (189 kgf-cm, 14 ft-lbf). Install the stud bolt with a "TORX" socket wrench (E8) type and achieve a final torque value of 9.5 Nm (97 kgf-cm, 84 in-lbf). The chain tensioner assembly requires you to clean and add engine oil to its O-ring before installation with 2 nuts that should be torqued to 9.0 Nm (92 kgf-cm, 80 in-lbf) while ensuring the O-ring maintains its original position. Fix the crankshaft pulley with the pulley set key in position on the key groove before using Special Service Tools: 09960-10010, 09962-01000 and 09963-01000 to secure the crankshaft pulley bolt at 138 Nm (1,407 kgf-cm, 102 ft-lbf). Use the plunger knock pin hook to separate it and ensure the slipper receives plunger force which moves it inside the chain tensioner when needed. The procedure involves applying engine oil to the O-ring of the crankshaft position sensor and installing it with 2 bolts which need to be torqued to 9.0 Nm (92 kgf-cm, 80 in-lbf) before installing the water pump assembly. Proceed by installing the engine mounting bracket RH with 47 Nm (479 kgf-cm, 35 ft-lbf) torque then install the V-ribbed belt tensioner assembly by torquing the bolt to 69 Nm (704 kgf-cm, 51 ft-lbf) and the nut to 29 Nm (296 kgf-cm, 21 ft-lbf). Set the head cylinder by applying seal packing on specific points before installation with nine bolts, two seal washers, two nuts, torquing Bolt A to 11 Nm (112 kgf-cm, 8 ft-lbf) with nut A and Bolt B to 9.0 Nm (92 kgf-cm, 80 in-lbf). The ignition coil assembly receives 4 bolts applying a torque setting at 9.0 Nm (92 kgf-cm, 80 in-lbf) before installing two engine wires using 2 nuts fixed at 9.0 Nm (92 kgf-cm, 80 in-lbf). Subsequently, the ignition coil connectors must be connected. The process begins with installing the engine mounting insulator RH through 4 bolts alongside 2 nuts that require torquing to 52 Nm (530 kgf-cm, 38 ft-lbf) before installing the oil reservoir bracket No. 1 using 2 bolts torqued to 7.8 Nm (80 kgf-cm, 69 in-lbf). Proceed with the generator assembly installation followed by the vane pump assembly installation and then install the fan assembly as well as the generator V belt. The service should begin by adding engine coolant followed by connecting the battery negative terminal at 5.4 Nm (55 kgf-cm, 48 in-lbf) torque before inspecting both engine coolant and oil leaks. To finish the installation process install cylinder head cover No. 2 using 2 nuts and 2 clips torqued to 7.0 Nm (71 kgf-cm, 62 in-lbf) along with the front wheel RH that needs a torque setting of 103 Nm (1,050 kgf-cm, 76 ft-lbf).
