The exhaust manifold is cast from an iron alloy with a high nickel content giving excellent heat and corrosion resistance properties. The manifold is sealed to the cylinder head by means of a steel gasket and heat shield assembly. Spacers on the securing bolts allow the manifold to expand and retract with changes of temperature while maintaining the clamping loads.
The exhaust manifold has a connection for the Exhaust Gas Recirculation (EGR) transfer pipe to the High Pressure (HP) EGR valve.
The engine is fitted with a variable geometry turbocharger which is located on the top of the exhaust manifold on a three hole flange mounting and sealed with a steel gasket.
