Before the removal of the exhaust manifold, the cable should be disconnected from the negative terminal of the battery. This is achieved by spraying penetrating oil on the exhaust manifold fasteners and let the oil to seep through the area. When filling the tank it is advisable to block the rear wheels so that the car will not roll; apply the parking brake and shift the transaxle lever to Park position. Lift the front of the car and put it on jackstands then remove the splash guard by unscrewing the mounting screws and pulling out the push-pins at the bottom of the engine compartment. The exhaust pipes can be disconnected from the manifolds by unthreading the nuts connecting the pipe to the manifolds, then the pipes can be lowered. On each manifold, take off all the bolts and heat shields and undo the self-locking nuts which secure the manifold to the
Cylinder Head, the latter should be discarded and new ones obtained for reassembly. Manifold should be checked for cracks, warpage, and other signs of damage and should be changed, if it is severely damaged. In installation, the use of a scraper is most appropriate in removing any remains of the gasket material as well as the carbons on the mating surfaces of the manifold to the cylinder head. Place a new gasket on the cylinder head studs, fit the manifold in position and screw in the nuts until they are tight, then tighten them in three equal increments to the torque recommended. Install the remaining parts in the reverse order, coat the studs with the engine oil and use the new self-locking nuts. lastly reconnect the battery and also start the engine and check of exhausts leaks.
