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.

2. Disconnect the battery ground cable.

3. Remove the upper intake manifold. For additional information, refer to Upper Intake Manifold Upper Intake Manifold.

4. Disconnect the fuel supply tube quick connect coupling from the fuel rail.

5. Detach the 2 wiring harness retainers from the RH and LH valve cover stud bolts.

6. Detach the 3 pin-type retainers from the fuel rail.

7. Disconnect the 6 fuel injector electrical connectors.

8. Remove the 8 lower intake manifold bolts and the lower intake manifold.
- Remove and discard the gaskets.

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 is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

NOTE: Clean and inspect all sealing surfaces.

Using new gaskets, install the lower intake manifold and the 8 bolts.

- Tighten in the sequence shown to 10 Nm (89 lb-in).
