    Q:
    What components and wiring should be removed or disconnected next for the Intake Manifold on the 2007 Saturn ION? Posted by Sheridan H.
    A:
    Next, remove the intake manifold cover, throttle body, and fuel rail. Disconnect electrical connectors and detach wiring harnesses from the manifold. Drain the coolant and remove the electric coolant pump on 2.0L supercharged models. If applicable, remove the supercharger. Also, disconnect vacuum hoses, including the brake hose, and mark them for reassembly. On 2.0L supercharged models, remove the alternator and engine cooling fan/shroud assembly. Position the air conditioning compressor aside without disconnecting the refrigerant lines. Remove the dipstick tube mounting bolt, set aside the dipstick and knock sensor wiring harness.
