APPLICABILITY: 2019-23MY Ascent
SUBJECT: Hood Panel Vibration

 

INTRODUCTION:

This bulletin provides a repair procedure to address a small number of customer concerns of the hood panel surface vibrating while driving.  This condition can result if the mastic (adhesive) used to bond the inner hood reinforcing panel to the outer panel (skin) begins to separate.

 

REQUIRED TOOLS AND MATERIALS INFORMATION:

 

SERVICE PROCEDURE / INFORMATION:

REMINDER:  Customer satisfaction and retention starts with performing quality repairs.

The instructions supplied with the 3M adhesive product contain information critical to performing an effective repair.  The product is readily available online and from most Auto Body supply outlets. Additional information is readily available on the 3M website: www.3MCollision.com.  Product directions also include important SAFETY precautions and processes to follow for a complete and lasting repair.

  • Use the photos below to identify the inspection areas and determine the potential repair points.

 

PREPARATION FOR REPAIR:

CAREFULLY remove the under hood insulation materials following the procedure in the applicable Service ManualNOTE:  The four (4) retaining clips (qty. 8 total) for both outer sections shown below p.n. 90814FC001 are 1-time use and MUST be replaced at reassembly.

  • Thoroughly clean all areas indicated in the photos above where the repair adhesive will be applied with alcohol wipes (or isopropyl alcohol on a clean shop cloth). All application areas must be completely free of any foreign material (grease, dirt) which could prevent proper adhesion to either panel.  Always allow the alcohol to dry completely before proceeding with application of the adhesive.

 

ADHESIVE APPLICATION:

  • Before applying adhesive, CAREFULLY insert the spacer between the inner and outer hood panels at the location (s) indicated in the above photo on the side intended for the repair. Use two spacers if both the left and right side need to be repaired.  Keep the edge of the spacer outside the gap as shown to make removal after the adhesive is cured easier.
  • Using the fine point tip of the applicator nozzle, CAREFULLY apply the adhesive between the outer and inner hood panels as indicated in the photo above. Apply enough material to adhere both panels, keeping the width of the adhesive approximately 18mm (3/4in.).
  • Use a clean shop cloth to wipe away any excess adhesive protruding from the edges of the application areas. Adhesive should not protrude from the edges of the inner openings after it is cured.  Follow the specific 3M product instructions for the applicable cure times.
  • After the adhesive is fully cured (24 hours at 73 degrees F ambient temperature), remove the spacer(s) to complete the repair.
