Disassembly and Assembly
Intake Manifold AssemblyDisassembly
1. Remove the bolts.
2. Separate the upper and lower intake manifolds and discard the lower intake manifold gasket.
3. Remove the bolts from the intake manifold turning valve and remove the valve.
4. Clean the upper and lower manifold with metal surface cleaner and inspect the internal passages and mating surfaces.
5. Allow the upper and lower intake manifolds to dry completely.
Assembly
1. Position the intake manifold turning valve and install the bolts.
2. Position a new lower intake manifold gasket and the upper intake manifold on the lower intake manifold and loosely install the bolts.
3. Tighten the bolts in two stages using the sequence shown.
^ Stage 1: Tighten to 2 Nm (18 inch lbs.).
^ Stage 2: Tighten to 10 Nm (89 inch lbs.).
