THIS BULLETIN CANCELS AND REPLACES BULLETINS 95-C-63 AND 95-C-63 (a) ISSUED MARCH 1996. ALL COPIES OF 95-C-63 AND

THIS ISSUE HAS REVISIONS TO BOTH THE SERVICE PROCEDURE AND THE CLAIMS INFORMATION. THE REVISED INFORMATION
IS SHOWN IN BOLD AND OR ITALIC TYPE.
To: All Chevrolet/Geo Dealers
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/Vehicle Involved
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 1994-95 Chevrolet C/K extended cab pickups equipped
with front seat belt assemblies having a double loop energy management system. A condition exists where in a frontal collision, if both the lap belt and
shoulder belt energy management loops release at/or near the same time, acceleration forces can cause the buckle release mechanism to activate and
allow the buckle to separate from the latch. If the buckle released, the system would fail to provide the appropriate occupant restraint performance.
Additionally, a small number of these vehicles equipped with light duty naturally aspirated diesel engines (L49), which were built with straight (no
energy management loops) front seat belt systems before and after the larger suspect population, may not meet the HIC (Head Injury Criteria)
requirements of FMVSS 208, "Occupant Crash Protection". In the event of a vehicle crash, the occupant of these seats may not be properly restrained.
To correct these conditions, dealers will remove the stitching that creates the energy management loop in the shoulder belt(s) on trucks with gas engines
or 6.5L H.O. turbo diesel engines (L65, VIN Code "F"). For vehicles with light duty 6.5L naturally aspirated diesel engines (L49) and light duty 6.5L
turbo diesel engines (L56), the retractor portion of the seat belt assembly(s) will be replaced with one having the newly designed energy management
twin loop system.
Involved are certain 1994-95 Chevrolet C/K extended cab pickups model built within the following VIN breakpoints:
The repair to be performed is determined by the seat belt system and the engine type currently in the vehicle. The service procedure clearly states the
repairs necessary for each engine.
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.
