1. Make sure that both throttle body and upper intake manifold gasket surfaces are clean.
2. Install throttle body gasket on the four studs of the upper intake manifold.
3. Install throttle body to upper intake manifold.
4. Secure throttle body to upper intake manifold with four retaining bolts. Tighten to 16-24 N.m (12-18 lb ft).
5. Reinstall engine coolant hoses and vacuum connections as necessary.
