    Q:
    How to remove and install an Intake Manifold in four cylinder engine on Saturn LS? Posted by Ljubomir A.
    A:
    Negative battery terminal cable is disconnected. Throttle body is removed. Any electrical connectors that would interfere with manifold removal are disconnected. Open the wiring harness clips and detach all wiring harnesses from the manifold. Manifold hoses may be marked prior to removal, ensuring correct reassembly. Then, remove the dipstick tube mounting bolt and position the dipstick to the side. After that, intake manifold mounting bolts and nuts have to be removed. The intake manifold can now be lifted from the engine compartment.Install a new gasket if necessary; otherwise, no need for replacingthe intake manifold gasket in case it is not damaged during theremoval process. The surfaces of both manifold and cylinder head must remain clean before installation. Putting the manifold over the studs on the cylinder head follows this step. Install bolls and nuts finger-tight and then tighten them. Bolls should be tightened to a specific torque value starting fromthe center bolls to ends until they are firmly tightened throughout.Therest of installation is just doing the opposite of removing steps.Reconnecting battery. Run engine check for vacuum leaks.
