MANIFOLDS AND EXHAUST SYSTEM – TD6 DESCRIPTION AND OPERATION The intercooler is mounted below the radiator, and receives compressed air from the turbocharger. By cooling the compressed air, the intercooler further increases the mass of air delivered to the inlet manifold. Exhaust Manifold The cast iron exhaust manifold is secured to the cylinder head using twelve studs with nuts. Three metal gaskets seal the manifold to the cylinder head. A flanged connection on the underside of the manifold provides for the attachment of the turbocharger. The turbocharger is attached to the flange with three bolts and sealed with a metal gasket. A second flange, located on the front of the manifold provides the connection point for the EGR pipe. The pipe flange is secured to the manifold with two bolts. There is no gasket between the EGR pipe and the exhaust manifold.
