Removal

 WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

 WARNING: Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.

  1. Release the fuel system pressure. For additional information, refer to Section 310-00 .
  1. If equipped, remove the 4 nuts and the strut tower cross brace.

  1. NOTE: The engine appearance cover rubber grommets may remain on the cover. If so, remove the grommets from the cover and install them on the intake manifold before installing the cover.

    Remove the engine appearance cover.
  1. Remove the Air Cleaner (ACL) outlet pipe. For additional information, refer to Section 303-12 .
  1. Disconnect the Throttle Body (TB) electrical connector.
  1. Disconnect the Evaporative Emission (EVAP) canister purge valve tube and electrical connector. For additional information, refer to the quick connect coupling procedure in Section 310-00 .
  1. Remove the crankcase ventilation tube. For additional information, refer to the quick connect coupling procedure in Section 310-00 .
  1. Disconnect the fuel supply tube. For additional information refer to the quick connect procedure in Section 310-00 .
  1. Disconnect the vacuum tube from the intake manifold.
  1. Position the heater hoses aside.
  1. Remove the 2 nuts and the LH heater hose support.
  1. Remove the 2 nuts and the RH heater hose support.
  1. Remove the LH and RH fuel rail insulators.
  1. Disconnect the 8 fuel injector electrical connectors.
  1. Detach the 4 wiring harness retainers from the rear of the intake manifold.

  1. NOTE: It is not necessary to remove the fuel rail from the intake manifold assembly.

    Remove the 4 fuel rail bolts.
  1. Loosen the 6 bolts and remove the intake manifold.

Installation

  1. NOTICE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris if found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

    NOTE: Clean the sealing surfaces with metal surface prep. Follow the directions on the packaging. Inspect the mating surfaces.

    NOTE: Fuel rail removed from graphic for clarity.

    Using new gaskets, install the intake manifold.
  1. Install the 4 fuel rail bolts.
  1. Attach the 4 wiring harness retainers to the rear of the intake manifold.
  1. Connect the 8 fuel injector electrical connectors.
  1. Install the LH and RH fuel rail insulators.
  1. Install the RH heater hose support and the 2 nuts.
  1. Install the vacuum tube assembly, the LH heater hose support and the 2 nuts.
  1. Position the heater hoses.
  1. Connect the vacuum tube to the intake manifold.
  1. Connect the fuel supply tube. For additional information, refer to Section 310-00 .
