Be certain that the catalytic converter's exhaust system has cooled, being as it is very hot while operating. Drop the
Muffler, pull out the pipe and then release the electric connection on the downstream
Oxygen Sensor. LEV vehicles need the
Exhaust Manifold support bracket be removed. After that, separate the catalytic converter from the exhaust manifold by removing its attaching bolts and discard the old flange gasket. Check for any blockages in the catalytic converter and look inside it for cracks or melted substrate using a camera or light, so you can find the issue before a replacement. Put the catalytic converter onto the exhaust manifold by placing a new flange gasket in between, fix the exhaust manifold support bracket and tighten the M10 bolt to 54 Nm, the M12 bolt to 95 Nm and the nut to 28 Nm. After connecting the manifold support bracket to the heat shield using a bolt, assemble the muffler and
Exhaust Pipe to the catalytic converter, make sure each support isolator from the suspension is properly fixed to the vehicle's underbody. Screw the fasteners of the catalytic converter to the exhaust manifold to 28 Nm, make sure all your components clear properly and tighten the band clamps to 47 Nm, but don't allow them to press against the surface. If the downstream oxygen sensor has been removed, insert it back and connect the electrical connector. After that, run the engine to look for leaks in the exhaust and check if it contacts the vehicle's body, making changes as needed.
