NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

1. With the vehicle in NEUTRAL, position it on a hoist. REFER to Lifting Points .

2. Release the fuel system pressure. REFER to Fuel System Pressure Release .

3. Disconnect the battery ground cable. REFER to Battery Disconnect .

4. Drain the cooling system. REFER to Cooling System Draining, Filling and Bleeding .

5. Remove the upper intake manifold. REFER to Upper Intake Manifold .

6. Disconnect the 6 fuel injector electrical connectors.





7. Disconnect the fuel supply tube-to-fuel rail quick connect coupling. REFER to Quick Connect Coupling . Position fuel supply tube aside.

- Remove the bolt from the fuel supply tube-to-rail bracket.






8. Remove the 2 thermostat housing-to-lower intake manifold bolts.





9. Remove the 10 bolts and the lower intake manifold.

- Remove and discard the intake manifold and thermostat housing gaskets.
- Clean and inspect all sealing surfaces.






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.

Using new intake manifold and thermostat housing gaskets, install the lower intake manifold and the 10 bolts.
