1) Disconnect negative cable (–) at battery.
2) Remove turbocharger assembly referring to Turbocharger Removal and Installation:K9K .
3) Loosen exhaust manifold nuts in numerical order (“1” to “8”) evenly as indicated in the figure, and remove them.
4) Remove exhaust manifold (1) with gasket from cylinder head (2).
Installation
Reference: Exhaust Manifold Inspection:K9K
1) Install exhaust manifold (1) to cylinder head (2) as follows.
a) Fit exhaust manifold to cylinder head with new gasket.
b) Tighten exhaust manifold nuts temporarily by hand.
c) Tighten exhaust manifold nuts specified torque by numerical order as shown in the figure.
Tightening torque
Exhaust manifold nut ( a ): Tighten 26 N·m (2.6 kgf-m, 19.0 lbf-ft) by the specified procedure.
2) Install turbocharger assembly referring to Turbocharger Removal and Installation:K9K .
3) Connect negative (–) cable at battery.
4) Check to make sure that there is no oil leakage and exhaust gas leakage at each connection.
