Special Service Tool 09226-10010 coupled with a hammer needs to be used for installing the timing chain cover oil seal properly before greening the lip of the seal with MP grease. Begin by clearing all old packing (FIPG) materials while maintaining contact surfaces of the timing chain cover along with cylinder head and cylinder block free from contamination. The LH cylinder head requires a new O-ring while continuous threads of Toyota Genuine Seal Packing Black or Three Bond 1207B and equivalent materials run at specified locations. Seal Packing 1282B and Three Bond 1282B or equivalent must be used when working on the water pump part. Apply the seal packing on the timing chain cover only within three minutes before installation then secure the fasteners within 15 minutes while avoiding packing at the designated area. Attach the oil pump drive rotor to the crankshaft timing gear before using 24 bolts along with 2 nuts to fasten it securely with a 23 Nm (235 kgf-cm, 17 ft-lbf) torque specification. The oil filter bracket sub-assembly requires new gasket installation before securing it with 3 bolts and 2 nuts, torque should be set to 19 Nm (194 kgf-cm, 14 ft-lbf). Install the VVT sensor as well as the camshaft timing oil control valve assembly before positioning both cylinder head cover sub-assemblies (LH and RH). Finish the installation by tightening the ignition coil assembly to 10 Nm (102 kgf-cm, 7 ft-lbf) followed by the intake air surge tank then add the oil sub-assembly and strainer sub-assembly of No.2 oil before securing the crankshaft pulley and sub-assemblies of No.2 idler pulley along with the V-ribbed belt tensioner and cooler compressor assembly but retain the generator assembly and vane pump based on need. Install the water inlet followed by the oil level gauge guide and air cleaner assembly and connect the ventilation hose No.2. Fully tighten all components after you install the fan with fluid coupling and the fan and generator V belt. Secure the radiator support seal upper while installing the battery together with the differential carrier assembly front and power steering link assembly. End your task by adding engine oil and coolant while inspecting for leaks before installing the V-bank cover along with its two nuts tightened to 7.5 Nm (76 kgf-cm, 66 in-lbf).
