The installation process for the exhaust manifold starts with placing a new gasket on the cylinder head whose "L" mark faces the manifold side while using the exhaust manifold sub-assembly LH temporarily for 8 new nut installations at a torque of 44 Nm (449 kgf-cm, 32 ft-lbf). Secure four bolts for the No. 2 exhaust manifold heat insulator then uniformly tighten them to 7.5 Nm (76 kgf-cm, 66 in-lbf). Place the steering intermediate shaft No. 2 sub-assembly in position next. Set the "R" mark on the new gasket facing the exhaust manifold direction before connecting the unit to the cylinder head temporarily. After installation adjust each of the 8 new nuts uniformly to their specified torque level. The No. 1 exhaust manifold heat insulator gets its installation through 4 bolts which should be tightened up to 7.5 Nm (76 kgf-cm, 66 in-lbf). After installing the front No. 2
Exhaust Pipe assembly proceed to set up the front propeller shaft assembly (for 4WD) and propeller shaft heat insulator (for 4WD). Proceed to install the front exhaust pipe assembly followed by the air switching valve assembly (for Bank 2), No. 2 air tube (for Bank 2), before connecting the No. 2 air injection system hose. The water by-pass pipe assembly should be installed by connecting two water hoses to the transmission oil cooler while securing the three bolts to 18 Nm (184 kgf-cm, 13 ft-lbf). Proceed to connect the No. 5 water by-pass hose to its clip before installing the heater outlet water hose and placing the engine oil level dipstick guide. To proceed install the air switching valve assembly followed by No. 3 air tube for Bank 1 then No. 2 air hose for Bank 1. Affix the air cleaner assembly together with the air cleaner hose assembly while adding engine coolant and verifying for any coolant leakage. After installing the throttle body cover sub-assembly you should put on the No. 1 engine under cover while conducting an exhaust gas leak inspection. Secure the four fender apron seals LH, rear LH, RH and rear RH by implementing proper clips.
