Turbocharged 1.5L engines have the exhaust manifold incorporated in the turbocharger. To take off the 2.0L engine exhaust manifold start with the battery by detaching the cable of the negative terminal then work on the exhaust manifold heat shield and the turbocharger. Fourth, the take off of the exhaust manifold support bracket by the use of the mounting nuts and bolt and the removal of the manifold through the removal of the mounting bolts of the manifold from the
Cylinder Head. The above models are as follows: Installation, prior to assembly, scrape the surfaces on cylinder head, manifold, and exhaust pipe with a scraper and brake system cleaner, check that both surfaces are flat and unbroken. Put a new gasket on the cylinder head and fit the manifold Tighten new exhaust manifold bolts to torque specs, starting at the center bolt and in an outward manner regularly to five minutes as the new bolts used have adhesive coating on it. The process of installation is the same as the removal and connecting the battery, after the start of the engine, one should look for exhaust leaks. The most vital preliminary steps for both 2.5L engines are: The negative terminal of the battery should be disconnected and the exhaust manifold heat shield should be removed and the car must be lifted on jack stands securely. Remove penetrating oil up to the core bolts and nuts of the connection of the catalytic converter to the manifold, and extract the catalytic converter. Loose the electrical connection of the oxygen sensor and set down the lead coming from the retaining clip. The exhaust manifold must be unbolted from the cylinder head and therefore, the bolts which secure the manifold must be loosened. In the same way, clean the mating surfaces as mentioned above that should be flat and without any blemishes, fit a new gasket and fit the manifold and tighten the bolt to the competitor torque uniformly. Align the flange of the catalytic converter with the one on the manifold, bolt them together and tighten the bolts, to complete the process follow the reverse process and reconnect the battery, start the engine and physically searching for exhaust leakage.
