CAMPAIGN: CARBURETOR CHOKE SHIELD

Subject: PRODUCT CAMPAIGN 82C23 CARBURETOR CHOKE SHIELD - 1982 C, K, P20-30 SERIES LIGHT DURY CHEVROLET TRUCKS EQUIPPED WITH RPO LT9 (5.7L V8 ENGINE)

Chevrolet Motor Division has determined that some 1982 C,K,P20-30 Series Light Duty Trucks equipped with 5.7 liter V8 engines (RPO LT9) were assembled with carburetor choke shields which may interfere with the engine air cleaner. This interference prevents the air cleaner from properly seating on top of the carburetor. The resulting gap between the air cleaner and carburetor may allow dust and dirt to enter the engine from unfiltered air. Left uncorrected, this could reduce useful engine life.

To prevent the possibility of this condition occurring, it will be necessary to install a new carburetor choke shield.

VEHICLES INVOLVED

Involved are certain 1982 C,K,P20-30 Series Light Duty Chevrolet Trucks equipped with RPO LT9 (5.7L V8 engine) within the following vehicle identification number breakpoints:

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.
