Before going further to remove the exhaust manifolds, anyone should first unplug the cable of the negative terminal of the battery then lift the car and put on car stands securely. Take off the splash shield from under the engine hood and use the penetrating oil on the studs and nuts of the exhaust pipe to manifold. For the front exhaust manifold, it is necessary, respectively, to remove the connection of upper wire to the oxygen sensor, to unlock the bolt fixed to the bracket of engine hoist, take out the dipstick tube, and to unscrew four bolts of the manifold basic junctions, which are available. Take off the right front wheel and inner fender splash shield, then, loosen the right front wheel lug nuts, lift the vehicle one more time. Then, the front exhaust pipe should be disconnected, followed by the drivebelt which is attached to the tensioner; the air conditioning compressor wiring should also be disconnected Next, the three compressor mounting bolts should be removed and then the compressor should be hung out of the way but not dropped out of the unit and the AC refrigerant lines should not be removed. Last of all unscrew the lower mounting nuts of the exhaust manifold and unbolt it from the cylinder head. Again, to get good access to the rear exhaust manifold, it is necessary to delete the air intake duct assembly and the EVAP purge solenoid. Lift the car, provide it with sufficient support, then loosen the middle exhaust manifold bolt, and then disconnect the wiring of the top oxygen sensor and then take off the front aspect of the exhaust pipe. Partial disconnection of the stabilizer bar, detachment of the heat shield of the exhaust manifold and then, the nuts that connect the manifold to the cylinder head must be unscrewed. During the installation process check the exhaust manifolds for crack and also clean the bolt threads so as to had no deformation. Scrub the contact area of mating surfaces on the exhaust manifold and cylinder head and put a new gasket in place and then slide the exhaust manifold over the studs and tighten the nuts on the studs. When tightening the nuts, do it starting from the middle going round the top row then round the bottom row and when reconnecting the EGR tube use anti seize compound on the threads. Lastly, join the battery back, switch on the engine, and inspect drips the engine is cold then conducted the test when the engine is hot.
