Important:
• | The intake manifold, throttle body, fuel injection rail and fuel injectors
may be removed as an assembly. If not servicing the individual components,
install the intake manifold as a complete assembly. |
• | DO NOT use the intake manifold gaskets again. Install NEW intake manifold-to-cylinder
head gaskets. |
- Install NEW intake manifold-to-cylinder head gaskets (1).
- Install the intake manifold.
- Apply a 5 mm (0.20 in) band of threadlock GM P/N 12345382
(Canadian P/N 10953489) or equivalent to the threads of the
intake manifold bolts. Refer to
Sealers, Adhesives, and Lubricants
.
Notice: Refer to Fastener Notice in the Preface section.
- Install the intake manifold bolts.
Tighten
- Tighten intake manifold bolts first pass in sequence to 5 N·m
(44 lb in).
- Tighten intake manifold bolts final pass in sequence to 10 N·m
(89 lb in).
- Install the manifold absolute pressure
(MAP) sensor (1), if previously removed.
The electrical
connector end of the sensor should be facing the front of the engine.
- Install the positive crankcase ventilation
(PCV) valve (2) and hose (1).
- Install the engine coolant air bleed hose and clamp onto the throttle
body.
