Set the new gasket on the cylinder head LH with the oval side facing backward before installing the exhaust manifold by using six fresh nuts that require 21 Nm (214 kgf-cm, 15 ft-lbf) torque. The next step involves implementing the No. 2 exhaust manifold heat insulator through 3 bolts which need torquing to 8.5 Nm (87 kgf-cm, 75 in-lbf). The installation of the exhaust manifold begins with inserting the new gasket onto the cylinder head RH side with the oval facing forward while paying attention to the correct orientation then tightening 6 new nuts to 21 Nm (214 kgf-cm, 15 ft-lbf). Proceed with installing the front
Exhaust Pipe assembly and then continue with front No. 2 exhaust pipe assembly installation for the Regular Cab Standard Deck, after which install the front No. 2 exhaust pipe assembly that excludes the Standard Deck Regular Cab models. The technician should install the air switching valve assembly. Complete the installation by connecting the cable to the negative battery terminal although some systems demand system initialization after the reconnection process.
