The installation of an exhaust manifold begins with installing the No. 1 manifold converter insulator that requires 4 bolts with 12 Nm (122 kgf-cm, 9 ft-lbf) torque. Place a new gasket onto the cylinder head while installing the exhaust manifold converter temporarily using 5 nuts that need to be tightened in the specified sequence to 35 Nm (357 kgf-cm, 26 ft-lbf). You should start with No. 2 exhaust manifold heat insulator installation using two bolts that require 12 Nm torque (122 kgf-cm or 9 ft-lbf) before adding four bolts to the No. 1 exhaust manifold heat insulator at the same torque rate. Coat the No. 2 manifold stay with a bolt along with a nut that requires 43 Nm (438 kgf-cm, 32 ft-lbf) torque followed by another bolt using a nut torqued at the same strength. Integrate the air fuel ratio sensor (for Bank 1 Sensor 1) along with the radiator hose clamp as well as the engine oil level dipstick guide and the engine oil level dipstick. When inspecting the front
Exhaust Pipe compression spring with a vernier caliper check its free length surpasses 41.5 mm (1.63 in.) otherwise replace the component. The surface requires cleaning with a wire brush before adding new gaskets that face the exhaust manifold converter while maintaining its correct position yet eliminating the use of any old gaskets. A fresh gasket follows to cover the front exhaust pipe's surface. Use 2 compression springs and 4 bolts to mount the front exhaust pipe along with torqueing bolt A and bolt B at 43 Nm pressure (438 kgf-cm, 32 ft-lbf). Finally, connect the heated oxygen sensor connector. Complete the task by setting up the generator assembly while checking for exhaust gas leaks throughout the system.
