Start the process by turning off the vehicle and taking out the negative cable of the battery before you start the repair process in order to remove the exhaust manifold and putting it back. Lift and firmly stabilize the frontend of the car, next, take off the nuts of the header pipe or the catalytic converter and exhaust manifold so that the pipe can be detached from the manifold. Subsequently, liberate the oxygen sensor if at all installed and then the EGR and air suction tubes from the manifold, if any. Take off the exhaust manifold shroud and the exhaust manifold bracket and its bolts. Working in a crisscross pattern from the center, take off the exhaust manifold-to-
Cylinder Head nuts as well as the manifold accompanied with the gaskets; dispose of the gaskets. In installation, use putty knife to clean gasket mounting surfaces and use only new self-locking bolts. Install the manifold with the new gaskets in place, starting with the middle nut of the exhaust manifold to cylinder head bolts and tighten the nuts, diagonally to 23 ft lbs. 35 Tighten the header pipe flange nuts to 32 Nm and the same nuts as used for connecting the converter to the manifold or as manifold bolts to 32 Nm. Remove and torque the exhaust manifold to oxygen sensor 33 ft. lbs. (45 Nm), the manifold bracket bolts to 16 ft. lbs. The camshaft sprocket bolts to 22 Nm, the crankshaft position sensor to 5 Nm, the intake manifold bolts to 105 ft. lbs., the manifold shroud bolts to 16 ft. lbs. (22 Nm). Last secure the converter shroud bolts to 9 ft. lbs. Crank the starter and check the exhaust for leaks by snapping a rubber APK gasket/choke plate between the intake and exhaust flange and setting the propeller at 12 Nm.
