  Q: How to remove and replace an exhaust manifold on 3.5L V6 Nissan Pathfinder?

  A: 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.
