  1. Remove the throttle body assembly. Remove and discard the gasket. Some models use a solid insulator below the throttle body instead of a regular gasket. This base may be removed after its retaining bolts are removed. If the insulator is in good condition and free of any cracks or distortion, it may be reused.
To install:
  1. Install a new gasket or insulator on the plenum. If an insulator is in use, tighten its retaining bolts to 16 ft. lbs. (22 Nm). Install the throttle body onto the studs.
The gasket or insulator is correctly installed in only one position; make sure the grooves and passages in the gasket align with the matching openings on the air chamber.
  1. Install the retaining nuts. Tighten them evenly and alternately to 16 ft. lbs. (22 Nm).
  2. Install the cruise control, throttle control and/or accelerator cables.
  3. Connect the vacuum hoses.
  4. Connect the coolant hoses.
  5. Refill the cooling system.
