The attachment process begins with applying new gaskets to the cylinder head and No. 2 air tube while positioning their gasket tab toward the engine front and their gasket claws toward the tube side. Secure the exhaust manifold by tightening first the 2 marked nuts (A) and 8 new nuts. After which apply an even torque to all unlabeled nuts, ultimately torque both A labeled nuts to 10 Nm (102 kgf-cm, 7 ft-lbf) for Nut A and 21 Nm (214 kgf-cm, 15 ft-lbf) for the remaining nuts. Fit the insulator to the exhaust manifold by installing two nuts which need to be tightened to 10 Nm (102 kgf-cm, 7 ft-lbf). The installation of the first No. 1 exhaust manifold heat insulator requires three bolts which need torque to reach 10 Nm (102 kgf-cm, 7 ft-lbf). The mechanics should apply 2 bolts to the No. 1 manifold stay while tightening them in sequence to reach a torque value of 40 Nm (408 kgf cm, 30 ft lbf). For the exhaust manifold sub-assembly LH reinstallation add the gasket while making sure its tab faces toward the engine back position before applying the designated nut torque schedule. The No. 2 exhaust manifold heat insulator requires installation via 3 bolts torqued to 10 Nm (102 kgf-cm, 7 ft-lbf) followed by torquing the No. 2 manifold stay with 2 bolts achieved at 40 Nm (408 kgf-cm, 30 ft-lbf). The propeller shaft heat insulator requires two bolts which should be torqued to 16 Nm (160 kgf-cm, 12 ft-lbf). Begin installing the front
Exhaust Pipe assembly together with the front No. 2 exhaust pipe assembly and center exhaust pipe assembly and tailpipe assembly. The installation of the engine oil level dipstick guide must be completed before conducting a leak test on the exhaust system. Any loose components should be tightened and broken parts should be replaced if necessary. Install the front fender apron seals by attaching specified numbers of clips and add the front fender splash shield sub-assemblies LH and RH.
