  1. Reverse removal procedure noting the following:
    • Use new intake manifold gasket (2). See Fig 4 .
    • Install fuel delivery pipe with fuel injectors to cylinder head referring to "Fuel Injector Removal and Installation.
    • Adjust accelerator cable (1) play and A/T throttle cable (2) play (for vehicle with A/T). See ACCELERATOR CABLE  and THROTTLE CABLE  .
    • Check to ensure that all removed parts are back in place. Reinstall any necessary parts which have not been reinstalled.
    • Refill cooling system.
    • Upon completion of installation, turn ignition switch ON but engine OFF and check for fuel leaks.
    • Finally, start engine and check for engine coolant leaks.
