To remove the intake manifold, first relieve the fuel pressure, disconnect the negative battery cable, and drain the cooling system. Next, disconnect the fuel rails and lines, capping them to prevent dirt entry. Remove the throttle body, label and disconnect all wiring, vacuum, and coolant hoses from the intake manifold, and then remove the distributor or camshaft position sensor depending on the model year. For models from 2006 and later, loosen the rocker arms to remove all pushrods, ensuring each is marked for reinstallation. Remove the manifold attaching bolts or studs using a Torx driver bit, noting their locations for reinstallation, and then take out the intake manifold, prying carefully to avoid damage. For installation, clean all old gasket material from mating surfaces, lightly oil threaded fasteners, and apply RTV sealant at the intersections of the cylinder head and block. Position the intake manifold gaskets over the tabs on the cylinder heads, install the front and rear manifold end seals, and apply RTV sealer on top of the end seals without allowing it to dry. Carefully lower the manifold into place, install the bolts and studs in the specified sequence to the correct torque, and if applicable, reinstall the thermostat housing with a new gasket. Complete the installation by reversing the removal steps, refilling the cooling system, reconnecting the battery, and running the engine to check for vacuum and fluid leaks.
