Cleaner Assembly, Air

Both installation steps related to the intake air resonator require tightening the bolt. Fasten the bolt by positioning the tab from the air filter box cap inside the No. 1 air filter box hose groove. The No. 3 intake control valve assembly can be installed using the 2 attached claws. Insert the 3 bolts on the air filter box sub-assembly with a torque setting of 5.0 Nm (51 kgf-cm, 44 in-lbf). Then link the hose and connector. When installing the air filter box cap sub-assembly you should place the air filter element in position then position the air filter box hose groove on top of the throttle body alignment tab before securing the clamp. The installation of the air filter box cap requires 2 bolts with clips tightened to 5.0 Nm (51 kgf-cm, 44 in-lbf) alongside connector attachment of 3 vacuum hoses and the mass air flow meter connector and No. 2 ventilation hose and fuel vapor feed hose assembly. Competently install the No. 1 air filter box inlet with 2 bolts while using 7.0 Nm (71 kgf-cm, 62 in-lbf) and 5.0 Nm (51 kgf-cm, 44 in-lbf) torque settings and finally connect the 2 vacuum hoses. Fasten the N.2 air filter box inlet through two bolts measuring 7.0 Nm (71 kgf-cm, 62 in-lbf) torque before setting both vacuum hoses and harness clamps. Before reattaching the battery cable users must initialize specific systems according to the installation guidelines. The battery tray installation should be followed by the battery placement then secure both the clamp with bolts and nuts applying 5.4 Nm (55 kgf-cm, 47 in-lbf). Begin by connecting the positive battery terminal followed by tightening the nut to 6.4 Nm and proceeding with the negative terminal and matching nut torque. In the final step you must install the cool air intake duct seal by utilizing 11 clips.

Service and repair work on the air filter box starts with removing the cool air intake duct seal through unfastening its 11 clips. First disconnect the battery by loosening the negative terminal nut before waiting 90 seconds to avoid Air Bag activation. After waiting, loosen the positive terminal and remove the retaining bolt to take out the battery with its clamp and the tray. You should start by withdrawing both air filter box inlet clamps from the number two position and proceed to detach the vacuum switching valve clamps and hoses before removing the two mounting bolts. Remove the two bolts at the No. 1 air filter box inlet after disconnecting its two vacuum hoses. After disconnecting 3 vacuum hoses attached to the air filter box cap sub-assembly users need to loosen the No.1 air filter box hose clamp and sever connections for the hose clamps and No.2 ventilation hose and finally remove the mass air flow meter connector. Significantly loosen or release two clips before unscrewing the two bolts to extract the air filter box cap sub-assembly and air filter element. Start by detaching the air filter box sub-assembly through the process of removing its 3 bolts while disconnecting hose and connector. To remove the No. 3 intake air control valve assembly, first separate two claws before you loosen its bolt to take out the No. 1 air filter box hose and subsequently loosen the bolt to remove the intake air resonator.
