Set the No.1 cylinder to TDC/compression position before you proceed to temporarily put the crankshaft pulley bolt with washer then turn the crankshaft clockwise to achieve timing mark alignment and verify correct pulley angle to stop piston and valve contact. Examine the timing belt for defects while ensuring it remains free of bending, twisting and oil, water and steam contact. At the same time, inspect for correct installation and timing cover gasket damage. The installation process starts with pulley cleaning followed by idler pulley and water pump leak and smooth operation checks while installing the crankshaft pulley bolt to prepare for counterclockwise crankshaft rotation and alignment of timing marks using Special Service Tool: 09960-10010 (09962-01000, 09963-01000) until the timing belt installation marks match the crankshaft and camshaft timing pulley marks. Position the timing belt tensioner assembly No.1 by converting the push rod and lining up holes before using two 27 Nm (280 kgf-cm, 20 ft. lbs.) torque bolts for temporary installation and checking timing marks when the crankshaft turns 2 full circles. Install timing belt guide No.2, engine mounting bracket RH with 2 bolts and a nut torqued to 28 Nm (286 kgf-cm, 21 ft. lbs.), timing belt No.2 cover and timing belt No.1 cover, both checked for gasket integrity and torqued to 8.5 Nm (87 kgf-cm, 75 inch lbs.), engine wire protector cover, crankshaft pulley aligned with the keyway and installed with Special Service Tool: 09213-54015 (91651-60855), 09330-00021 torqued to 220 Nm (2250 kgf-cm, 162 ft. lbs.), generator bracket No.2 torqued to 28 Nm (286 kgf-cm, 21 ft. lbs.), engine mounting stay No.2 RH with bolt torqued to 64 Nm (653 kgf-cm, 47 ft. lbs.) and wire harness bracket with bolt torqued to 8.4 Nm (85 kgf-cm, 74 inch lbs.), engine moving control rod with 5 bolts torqued to specified values, followed by the installation of the vane pump V belt, V (cooler compressor to crankshaft pulley) belt No.1, inspection of drive belt deflection and tension, and finally the installation of the cowl top panel sub-assembly outer front, cowl top to cowl brace inner No.1, wiper link assembly, front wiper arms LH and RH, and front wheel RH.
