HOOD SHEET METAL MOVEMENT (NEW ADHESIVE APPLICATION)

VEHICLES AFFECTED: 1978-1988 S/T, C/K, R/V, G, ------------------ AND M MODELS

Some vehicles may experience a hood flutter condition due to a loss of adhesion between the hood panel and underhood support braces.

When the vehicle is driven, air enters the engine compartment and forces the hood upward. Variations in the road surface and in the amount of air passing through the engine compartment cause the hood panel to move up and down (Flutter).

To correct this condition remove the adhesive which is not bonding the hood panel to the underhood support braces. Remove all grease and dirt from the area where new adhesive will be applied. The replacement adhesive should be a fast curing structural adhesive such as that offered in 3M Hood Flutter Repair Kit P/N 051135-08105. Other suitable adhesives may exist.

For vehicles under warranty use:

Use the most applicable labour operation from the Canadian Labour Time Guide and claim 0.3 hours.

Add: .1 hr. - with hood insulation

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
