SPECIAL POLICY: LACK OF SPECIFIED 20 GAL. FUEL TANK

Model and Year: EARLY 1988 CHEVROLET S10 TRUCKS (EXCEPT X81 - PRICE LEADER AND X9H - 2,000 LB CAPACITY PAYLOAD)

General Motors has determined that instead of the specified 20 gallon fuel tank (RPO, NK2), a 13 gallon fuel tank was installed in certain 1988 S10 Pickup and Chassis Cab Model Trucks (except options X81 and X9H) built at the Moraine and Shreveport assembly plants. The price label on an affected vehicle states that the unit has a 20 gallon tank (the price of the 20 gallon tank is included in the base vehicle price) but the absence of NK2 from this service information label indicates that it has a 13 gallon fuel tank. Dealers were notified of this matter on November 10, 1987.

SPECIAL POLICY ADJUSTMENT

Original owners of record who purchased their vehicles on or before November 10, 1987, will be contacted and offered a choice of the following:

A. $100.00 total reimbursement adjustment incentive.

OR

B. Installation of a 20 gallon fuel tank at no charge.

When the original purchaser requests reimbursement, that customer MUST sign and date the Option Selection form included as part of the owner letter (extra copies to be reproduced locally, if needed) . The signed form and a copy of the check issued to the owner is to be attached to the dealer's file copy of the request within thirty (30) days after dealer credit is received and retained for twenty-four (24) months from the date of credit.

For vehicles in dealer inventory after November 10, 1987, and not sold, dealers were requested to disclose this condition to the prospective purchaser and to make an appropriate price adjustment in the amount of $51 MSRP from the MSRP for the base vehicle. This is Chevrolet's calculation of the portion of the vehicle's MSRP attributable to the larger fuel tank ($44.01) dealer price.

For vehicles still in dealer inventory and not sold in January, 1988, new price labels reflecting the above were sent to dealer's with the request that they be applied to the affected vehicles. Dealer's should also take the necessary steps to disclose to customers the size of the fuel tank installed in an affected vehicle prior to sale.

The Special Policy Adjustment will remain in effect until May 15, 1989 with no mileage restriction.

This Special Policy Adjustment Bulletin should be filed in the three-ring binder previously furnished to the dealer by General Motors.
