Subject: PRODUCT SAFETY CAMPAIGN 95-C-56(a) - FAN BLADE REPLACEMENT

--- REISSUE ---

Model and Year: 1995 S/T TRUCKS WITH 4.3L ENGINES (VIN "Z" - RPO LB4) AND (V N "W" - RPO L35) WITH AIR CONDITIONER (C60)

To: All Chevrolet Dealers

THIS BULLETIN REPLACES PRODUCT SAFETY CAMPAIGN BULLETIN 95-C-56 ISSUED OCTOBER, 1995. SPECIFICALLY, THE SERVICE SECTION HAS BEEN REVISED TO INCLUDE THE INSPECTION PROCEDURE. THE REVISED INFORMATION IS PRINTED IN BOLD TYPE. ALL COPIES OF THE ORIGINAL BULLETIN DATED OCTOBER, 1995 SHOULD BE DESTROYED.

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to repair within sixty (60) days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.

If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter that is being sent to owners, the owners are being instructed to contact the Chevrolet Customer Assistance Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.

DEFECT INVOLVED

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1995 Chevrolet S/T Pickup and Utility trucks equipped with air conditioning and 4.3L engines. Some of these vehicles may exhibit fan-blade rivet breakage which could lead to fan blade separation from the spider. If this should occur while the hood is open, a person working under the hood of the vehicle or in the vicinity of the vehicle could be struck by the fan blade and injured.

To correct this condition, dealers will inspect and replace if necessary, the existing fan with the current release fan having thicker rivets.

VEHICLES INVOLVED

Involved are certain 1995 Chevrolet S/T Pickup and Utility trucks equipped with air conditioning and 4.3L engines, and built within the following VIN breakpoints:

PLANT YEAR MODEL PLANT CODE FROM THROUGH ------------------------------------------------------------------ 1995 S/T Truck Linden "K" SK127759 SK151952 1995 S/T Truck Moraine "2" S2100234 S2135046 1995 S/T Truck Shreveport "8" S8119447 S8151095

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

PARTS INFORMATION

Parts are to be obtained from General Motors Service Parts Operations (GMSPO). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a "C.I.O." order with no special instruction code, but on an advise code (2) .

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.
