Delete the turbocharger. Remove the nuts and clamps that retain the heater lines to the exhaust manifold. In case of such models, take off the screw that holds the heater tube(s) onto this exhaust manifold. Ensure to put aside your spacers. Remove the housing for the air filter together with air intake duct hose. On models so equipped, remove heat shield/noise reduction panel from exhaust manifold. Remove EGR cooler. Take out rear bolt lock plates. Take away Exhaust Manifold Bolts, Exhaust Manifold Gaskets and Spacers. Clean both mounting surfaces on manifold and cylinder head and clean threads on exhaust manifold mounting bolts.. Apply new gaskets to manifolds ensuring antiseize compound is applied to bolt threads.. Start tightening manifold bolts from center ones gradually proceeding outward following torque sequence given below until all are tightened as specified in torque specification.. Rest of installation is reverse of removal.NOTE: This stud goes into the hole for the lower rear and two front cylinders.

The initial steps are to disconnect the cable from the negative terminal of the battery and remove the engine cover. If you're removing the right-side manifold, also remove the air filter housing.

Tighten the heat shield bolts to the specified torque and then install the remaining components in the reverse order of removal.

Attach an engine support fixture or an engine hoist to the engine lift points with a chain. Remove the engine mount through-bolts, then raise the engine enough to get access to the exhaust manifold bolts.

Install the exhaust manifold(s) and fasteners. Tighten the bolts/nuts to the specified torque, starting with the center bolts and proceeding to the outer ones. Approach the final torque in three steps.

The bolts and brackets retaining the heater line(s) to the exhaust manifold. The bolt retaining the heater pipe(s) to the exhaust manifold. The air filter housing and the air intake hose. The heat shield/noise reduction panel from the exhaust manifold. The EGR cooler. The rear bolt lock plates. The exhaust manifold bolts, exhaust manifold, gaskets, and spacers.

My system does not give me the material most parts are made out of, but given this part's weight and dimensions, it appears far more likely to be aluminum to cast iron.
