1. Remove the windshield. Refer to Windshield Replacement in Stationary Windows.
2. Remove the bolts from the modular dash assembly and from the cross car beam.

Caution: Refer to Battery Disconnect Caution in the Preface section.




3. Disconnect the negative battery cable.
4. Remove the brake master cylinder.

Notice: After removing the brake line fitting nuts, do not excessively pull or bend the brake lines away from the master cylinder.

5. Remove the brake line fitting nuts from the master cylinder.




Notice: Plug the open lines and fittings to prevent brake fluid loss and contamination.

6. Remove the 2 master cylinder-to-brake booster attachment nuts.

Notice: Be careful not to bend the brake lines.

7. Remove the master cylinder.




Caution: When using tools that may create smoke when cutting or heating urethane adhesive, work should be done in a well ventilated area and/or with a NIOSH/MSHA approved air supplied respirator to prevent possible harmful exposure. When the urethane adhesive is heated enough to give off smoke, high levels of methylene diisocyanate may be present. Unprotected exposure to methylene diisocyanate may result in severe, chronic, debilitating respirator problems.

8. Remove the dash insulator.
9. Cut the modular dash assembly above the smile joint in the area of the dotted line.
10. Using piano wire, cut the sealing joint to the dash in the shock tower area.
11. Heat the joint with a heat gun to loosen the adhesive bond. Pull the remainder of the modular dash flange from the adhesive joint.
12. Remove the old adhesive from the smile joint. Clean the joint areas with isopropyl alcohol in the sealer path areas and prepare for the new adhesive (P/N 12345633).




Caution: This joint must seal completely. It must be tested to ensure there are no water leaks or paths for carbon monoxide to intrude into the passenger compartment.

13. Apply adhesive into the smile joint and sealing areas as shown in the illustration.
14. Install the dash ensuring proper engagement of the smile joint.



15. Check the sealing of the dash assembly to the front body hinge pillar (3), shock tower (2), windshield pillar (4), and instrument panel reinforcement panel (1). No water and air leaks are permissible.

Notice: Refer to Fastener Notice in the Preface section.
