Nissan 14002-9S210 Exhaust Manifold With Catalytic Converter Driver Side

Disconnect the cable from the negative terminal of the battery. Block the rear wheels and set the parking brake. Raise the front of the vehicle and support it securely on jackstands, then remove the lower splash shield from below the engine if equipped. Remove the front exhaust pipe from the vehicle. Unbolt the lower heat shields and remove the catalytic converters from the exhaust manifolds. Disconnect the oxygen sensor connectors. Remove the heat shield from the manifold(s). Note: When removing the right exhaust manifold it will be necessary to remove the coolant tube from the right side of the engine. Also remove the power steering pump reservoir from the inner fenderwell and position it aside without disconnecting the fluid lines to allow access to the manifold. Remove the manifold-to-head nuts/bolts and detach the manifold and gaskets. Use a scraper to remove all traces of old gasket material and carbon deposits from the manifold and cylinder head mating surfaces. Position the new exhaust manifold gaskets over the studs on the cylinder head. Install the manifold and thread the mounting nuts/bolts into place. Working from the center out, tighten the nuts/bolts to the specific torque in three or four equal steps. Reinstall the remaining parts in the reverse order of removal. Run the engine and check for exhaust leaks.

The catalytic coating on the monolith contains palladium, platinum, and rhodium.

To replace a catalytic converter, you should remove the flange bolts and disconnect the exhaust pipe from the catalytic converter. If necessary, remove the exhaust system hangers and move the exhaust pipe rearward while supporting the exhaust system. Then, remove the flange bolts to separate the catalytic converter from the exhaust pipe or exhaust manifold. Installation is the reverse of removal.

Disconnect the cable from the negative terminal of the battery. Raise the front of the vehicle and support it on jackstands. Spray penetrating oil on the exhaust manifold fasteners and allow it to soak in.
