Manifold, Intake

The starting step to remove the intake manifold requires users to disconnect the battery cable from its negative terminal. The technician begins by taking off the cowl top ventilator louver sub-assembly and completes the task by handling front fender splash shield sub-assemblies on both sides. After that drain the engine coolant from the vehicle by removing the No. 1 engine under cover sub-assembly. The intake process begins with air cleaner hose assembly separation that requires removing the vacuum and no. 2 ventilation hoses and loosening the 2 clamps before extracting the air cleaner hose. Detach the ventilation hose from one side of the cylinder head cover ventilation pipe while disconnecting all other installation components including the 2 water by-pass hoses, throttle body connector, No. 1 ventilation hose, purge VSV connector and purge line hose from the VSV as well as the vacuum switching valve connector (ACIS). Start the procedure by removing the No. 1 engine cover sub-assembly followed by the No. 3 engine cover and disconnection of the 3 wire clamps from the 3 wire brackets. Unbolt and remove the intake manifold wire bracket followed by detachment of its two nuts, 8 bolts and intake manifold and its accompanying two gaskets. To proceed, disassemble the ventilation hose assembly through removal of 2 bolts and harvesting the intake manifold hose. Start by unfastening the 2 bracket bolts of the No. 1 V-bank cover bracket and then dispose of the bracket before unfastening the V-bank cover bolt from the intake manifold. You must detach the No. 2 V-bank cover bracket sub-assembly through the removal of its bolt and bracket. The throttle body assembly requires removal of its 4 bolts and subsequent disassembly of the throttle body along with its gasket. First remove the vacuum hoses from the vacuum switching valve then disconnect them and remove the bolt and valve together. First disconnect the purge line hose from the intake manifold before removing both bolt and purge Valve Substrate Ventilator. To finish the procedure remove the wire harness clamp bracket with the removal of its 2 bolts and 2 wire harness clamp brackets.

Install the No. 2 V-bank cover bracket sub-assembly with a bolt, torqued to 10 Nm (102 kgf-cm, 7 ft-lbf).

Remove the bolt and wire bracket from the intake manifold, followed by the 2 nuts, 8 bolts, intake manifold, and 2 gaskets.
