There's not a lot of information that precedes the intake manifold removal but before removing the intake manifold one should always relieve the fuel system pressure. Remove the cable from the negative terminal of the 12-volt battery always conduct the initialization process before the reconnection. Remove the throttle body. Remove the PCV and vacuum hoses from the rear of the intake manifold with respective labels and detach for pre '09 models eliminate all wires that interfere. For the year 2010 to remove this EGR tube assembly, MAP sensor and also the vacuum switching valve while at the same time placing label on and eradicating all the disturbing cables. Also, further, take off the dipstick assembly including the O-ring and further, disconnect the two vapor hoses. Subsequently, point to eliminate the intake manifold nuts, bolts, and support bracket bolts as well as the manifold and gasket from the engine. For installation, two pieces of mating surfaces, the intake manifold and the cylinder head must be cleaned with lacquer thinner or acetone. If you see any leakage on the gasket, check the manifold for warping and sanded if it is warped. Place a new gasket over the manifold studs and put the manifold in place on the cylinder head; put in the nuts, bolts and brackets. Re-torque all the nuts and bolts that hold the manifold to the cylinder head in equal steps, either three or four times, starting from the center in order to avoid distorting the metal. Whereas to secure the proper torque on the manifold-to-cylinder head bolts you next tighten the lower bracket bolts. Insert back the remaining parts in the reverse order you used to remove them, check the level of the coolant and pour some if the level is low. Initially check the throttle linkage when it is cold and before engaging the engine into the operating mode. Start engine and examine for exhaust gas color, and search coolant and vacuum leaks, perform road test to feel all accessories in operation, and where fitted test the cruise control system.
