FASCIA OUTER BRIGHT MOLDINGS GAPPED (REPOSITION MOLDINGS)

SUBJECT: FASCIA OUTER MOLDINGS LOOSE OR GAPPED TO FASCIA AT RADIUS

MODELS AFFECTED: 1992 ELDORADOS

Some 1992 Eldorados may experience a condition where the outer fascia bright moldings are loose and/or gapped to the fascia at the inner corner radius. This condition may be caused by insufficient retention of the outer bright molding. Revised front outer moldings with snap tabs added at the corners for improved retention were in production during December, 1991. Revised rear outer moldings are expected to be implemented by the end of January, 1992. Vehicles built after October have redesigned fascias to accept the new molding with the additional snap tab. Fascias on vehicles prior to October cannot accommodate the new molding.

To correct this condition use expandable foam to fill the cavity under the moldings and bond the outer and center moldings together. You will need expandable foam, such as Kent Industries' two component Ure-Foam (P/N 10600) or equivalent, and a fairly stiff extension hose 7-10" long to fit on the end of the applicator/mixer.

NOTICE: If using an equivalent foam product, test the foam prior to performing these procedures to ensure no paint or other damage will result from use. Also ensure that the dried foam can be easily cleaned from the fascia and/or molding surfaces if required.

1. Properly position outer molding. With one hand on end of outer molding at wheel opening, carefully pull outer molding toward center molding while pushing inward at molding corner. Refer to Figure 1. Adjust as necessary to provide best fit to fascia.

2. Tape joints to prevent foam from escaping between or around moldings. First tape the joint between the outer and center moldings, then tape the front and back edges of each molding to the fascia. Extend the taped area 6" to either side of where the moldings join. Refer to Figure 2.

3. Hoist vehicle.

4. Carefully drill a small hole in the fascia underneath the outer molding close to the bumper beam. Refer to Figure 3 for hole location on front and rear fascias. The hole diameter should be 1.5 to 2 times the diameter of the extension hose to allow proper hose positioning.

IMPORTANT: Drill all required holes at this time, front and rear, so that the foam may be applied with minimal waiting time between applications.

5. Prepare the expandable foam according to manufacturer's directions. Assemble the extension hose to the foam canister. The extension must be stiff enough to avoid kinking and allow proper positioning so the foam will be located correctly.

6. Squeeze a small amount of the foam onto a piece of cardboard or paper to get an idea of the foam expansion rate and the application time required to fill the cavity.

7. Feed the extension hose into the hole in the fascia, positioning the end at the molding interface as shown in Figure 4. If repairing a rear fascia molding, approximately 4.5" of the hose will be fed into the fascia; 3.5" for a front molding.

8. Apply foam to the cavity between the molding and fascia. Allow sufficient application time to fill the cavity and expand to either side of the molding joint. Continue to apply foam as the hose is slowly withdrawn from the fascia. Do not apply excessive foam or squeeze-out may occur where moldings are not taped.

9. Allow foam to cure according to manufacturer's directions.

10. Lower vehicle and remove tape from moldings and fascia.

11. Clean up any excess foam according to manufacturer's recommendations.
