Subaru 14010AA102 Manifold Exhaust RH

You can Select Your Vehicle to check if 14010AA102 fits your vehicle.

Start by disconnecting the cable from the negative terminal of the battery in order to remove the exhaust manifold. Next, jack up the vehicle and make sure it is securely supported on jackstands. Take off engine splash shields and separate front as well as rear oxygen sensor connectors. Remove heat shields from non-turbocharged models' exhaust pipes and manifold, then remove both cylinder head nuts from exhaust manifold and bolts from exhaust manifold joint on straight six side. On turbocharged models, take off heat shields, then separate right side joint pipe fasteners between turbocharger and manifolds, as well as nuts that attach both cylinder heads to exhaust manifolds. Lastly get rid of the exhaust manifold itself. To install new ones, clean the mating surfaces of each cylinder head, manifold or manifolds and exhaust pipe(s), making sure they are flat without any damages. Put new gaskets on; put a manifold onto cylinder heads; and then tighten down bolts evenly. Afterward attach center pipe or turbocharger joint pipe to this manifold while tightening up all nuts equally connected thereunder. Finally reinstall everything following reverse steps involved in taking it apart but remember to reconnect battery first before testing for proper ventilation once again when turning engine on.

The first step in order to approach the exhaust manifold requires a user to disconnect the cable that is connected to the negative terminal followed by lifting the car and placing it over some jack stands. Then, unlock the engine splash shield and cut off the front and rear oxygen sensor connectors. For non-turbocharging remove the heat shields of the exhaust pipes and exhaust manifold: The bolts and studs must be coated with penetrating lubricant to avoid thread stripping. It is necessary to unscrew bolts on the exhaust manifold connector at the center exhaust pipe, and then it is possible to unscrew nuts on the exhaust manifold on both cylinder heads and to take off the manifold. Turbocharged models are similar; first, remove the heat shields, then undo the bolts in the turbocharger joint pipe, and the nuts in the exhaust manifold and a center exhaust pipe if needed. For installation, it is good that the mating surfaces on the cylinder heads, manifold, and exhaust pipe are cleaned with a scraper and solvent and checked that the surfaces are flat and non-damaged. Replace manifold gaskets, fit the manifold on the cylinder head and through bolts and torque to harmonize with recommended torque figure produced by the manufacturer. Screw the coupling nut with the center pipe or the turbocharger joint pipe on the manifold and make equal and tight torque. As a final step, reverse all the steps that were done during removal and join the battery, finally, start the engine and ensure that it has no exhaust leak.

Remove the engine splash shield(s) and disconnect the front and rear oxygen sensor connectors.
