Lower Intake Manifold Removal/Installation

LOWER INTAKE MANIFOLD REMOVAL/INSTALLATION






Removal

WARNING:
- Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.
- Fuel in the fuel system remains under high pressure even when the engine is not running. Before repairing or disconnecting any of the fuel system components, the fuel system pressure must be relieved to prevent accidental spraying of fuel, causing personal injury or a fire hazard.

1. Release the fuel system pressure. See FUEL SYSTEM PRESSURE RELEASE.
2. Disconnect the battery ground cable. See BATTERY DISCONNECT.
3. Remove the upper intake manifold.
4. Disconnect the engine coolant temperature (ECT) sensor electrical connector.
5. Disconnect the fuel supply tube quick connect coupling at the fuel rail. See QUICK RELEASE COUPLING - DOUBLE LOCKING.
6. Disconnect the fuel rail pressure and temperature sensor electrical connector and vacuum tube.
7. Disconnect the 6 fuel injector electrical connectors and the 2 wire shield pin-type retainers.
8. Remove the 8 lower intake manifold bolts and the lower intake manifold.
- Remove and discard the gaskets.

Installation




1. Install new gaskets. Position the lower intake manifold and install the bolts.

- Tighten in the sequence shown to 10 N.m {0.1 kgf.m, 89 in.lbf}.

NOTE: Clean and inspect all sealing surfaces.

2. Connect the 6 fuel injector electrical connectors and the 2 wire shield pin-type retainers.
3. Connect the fuel rail pressure and temperature sensor electrical connector and vacuum tube.
4. Connect the fuel supply tube quick connect coupling at the fuel rail. See QUICK RELEASE COUPLING - DOUBLE LOCKING.
5. Connect the ECT sensor electrical connector.
