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

You can Select Your Vehicle to check if 14002-9S210 fits your vehicle.

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 converter is an emission control device that reduces pollutants in the exhaust gas stream, including lowering the levels of oxides of nitrogen (NOx), hydrocarbons (HC), and carbon monoxide (CO).

For the right manifold, working from above, remove the manifold heat shield. Remove the upper row of manifold nuts. Work from the ends toward the middle when removing the manifold fasteners. Working from below, remove the lower row of manifold fasteners and remove the manifold from the engine.

Disconnect the cable from the negative terminal of the battery.

Working under the vehicle, disconnect the front exhaust pipes from the vehicle. On California models, detach the heat shields from the pre-catalytic converter, disconnect the oxygen sensor connectors, and remove the pre-cat from the exhaust manifold. If both exhaust manifolds are being removed, both pre-catalytic converters or front exhaust pipes must be removed. On 2WD models, remove the front suspension crossmember first, to facilitate removal of the front exhaust pipes.

Disconnect the EGR pipe from the exhaust manifold.

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