Install in the reverse order of removal.

•	When installing, replace with new gaskets.

•	When installing the intake manifold, tighten the bolts and nuts with pre-torque first, and then tighten the bolts and nuts with specified torque in the sequence shown.

After replacing the intake manifold, be sure to delete the previous VCMA adaptive value by performing the 'resetting adaptive values' procedure using KDS.
