To remove the exhaust manifold, first one needs to disconnect the cable from the negative terminal of the battery, then by putting a jack and putting some stands the vehicle has to be lifted from the ground. Treat the exhaust pipe to manifold studs and nuts with penetrating oil, and, if equipped, pull the connector off the oxygen sensor. Lose the nuts which holds the exhaust pipe(s) to the manifold(s) and the engine top front cover bolts as well as the rear cover nuts. Take out the spark plug wires and spark plugs of the side where the work is being done or of both if both manifolds have to be removed. For the right side manifold release the connected pipe for the oil dipstick while for the left side release the steering shaft connected to the steering gear. Subsequently, it is required unlatch the mounting bolts to relieve the exhaust manifold and cylinder head connection, and the heat shields. During installation you need to inspect the manifold for cracks and the bolt threads for cleanliness. The surfaces where the gasket sits, that is the mating surface of the manifold and cylinder head must be clean, and use a gasket scraper to remove carbon deposits and gasket material without damaging the aluminum. Place the heat shields, bolts and gaskets on the manifold with the help of retaining tabs, that holds the assembly together. Place an epoxy adhesive with medium strength from the fourth thread of the bolts on the nut threads, then fit the manifold onto the cylinder head then tighten the mounting bolts only to finger tightness. In two runs, using a torque wrench, start tightening the bolts from the middle to the outside and if need arises, flatten the exposed of the exhaust manifold gasket against the cylinder head. Perform the process of installation in an order inverse to the process of removal and finally, turn on the engine and check the exhaust.
