2007 Toyota Matrix Parts Questions & Experts Answers

• Q: How to remove the timing chain on 2007 Toyota Matrix?

  A: Starting the removal process of the timing chain requires users to first disconnect the battery negative terminal followed by removing the front wheel RH and engine under cover RH. The procedure starts by removing cylinder head cover No. 2 after unfastening its 2 nuts along with 2 clips. The process requires draining the engine coolant. Detach the fan and generator V belt following vane pump assembly separation and finally remove the generator assembly. The engine mounting insulator RH requires removal with 2 bolts followed by separating the oil reservoir bracket No. 1 support system with a wooden block on a jack and removing 4 bolts together with 2 nuts while maintaining engine support during the process. The procedure to remove 4 ignition coils requires dismantling the engine wire first followed by disconnecting its connectors, removing 2 nuts and separating engine wire and then the removal of 4 ignition coils. The ventilation hoses must be disconnected from the cylinder head cover first before removing the engine wire clamps from their bracket. Afterwards you can detach the cylinder head cover by removing nine bolts, two seal washers along with two nuts and three clamp brackets. Start by taking off the bolt and nut from the V-ribbed belt tensioner assembly. After jacking the engine repeatedly you can take off the engine mounting bracket RH because its bolts need removal. The water pump assembly requires removal before separating the crankshaft position sensor through 2 bolt removal. To set the No. 1 cylinder at TDC/compression position synchronize the timing mark "0" on the timing chain cover with the crankshaft pulley groove and verify proper alignment of the camshaft timing gears. Special Service Tool: 09960-10010 (09962-01000, 09963-01000) allows you to remove the crankshaft pulley before proceeding with the removal of the chain tensioner assembly No.1 through 2 nuts. Keep the crankshaft stationary before turning it because the chain tensioner is not in place. The timing chain or belt cover sub-assembly removal requires a "TORX" socket wrench (E8) to unscrew the stud bolt and 12 bolt and 2 nut removal followed by a slow and careful prying of the cover toward its removal. Disassemble the timing chain or belt cover oil seal before taking off the crankshaft position sensor plate No.1 along with the chain tensioner slipper. Prise the chain sub-assembly out with 2 screwdrivers in careful manner while safeguarding both the engine and keeping valves away from pistons. Begin installation by positioning the No. 1 cylinder at TDC/compression whereas the camshaft timing gears should align before installing the chain onto the crankshaft timing gear with yellow mark link at its correct position. The crankshaft timing gear and chain need to be mounted onto the camshaft timing gears with Special Service Tool: 09223-22010. Attach the chain tensioner slipper with force of 18.5 N m (189 kgf cm, 14 ft. lbf) before adding the crankshaft position sensor plate No.1 with "F" mark forward. To install the timing chain or belt cover sub-assembly place a new oil seal lip inside Special Service Tool: 09223-22010 and tap it into position while applying continuous bead of seal packing and following bolt and nut torque specifications. After applying lubricant to the O-ring of chain tensioner assembly No.1 the technician should install the component then torque the crankshaft pulley to the recommended values. The installation requires the crankshaft position sensor along with water pump assembly, engine mounting bracket RH, V-ribbed belt tensioner assembly, cylinder head cover sub-assembly, ignition coil assembly, engine mounting insulator RH, generator assembly, vane pump assembly, and fan and generator V belt. Conclude the procedure by connecting the negative terminal of the battery then check for fluid leaks while installing engine cover No.2 and installing the right-hand front wheel. All parts must receive their precise torque requirement.
