Owner Letter
Dear GMC Truck Owner:
Your complete satisfaction with your 1994 GMC Truck, equipped with a 6.5L Electronic Fuel Injection (EFI) Diesel Engine, is most important to GMC
Truck. We want your 6.5L diesel to satisfy all your driving needs and wish to inform you that enhancements are available to improve your engine's
driveability.
The 1994 6.5L EFI Diesel Engine in your truck is equipped with an electronic fuel injection pump which is controlled by a powertrain control module
(or computer). CERTAIN Trucks may exhibit some driveability concerns such as poor throttle response, stalling, misfire, poor hot or cold starting,
extended cranking of a hot engine, or stalling after start. Trucks equipped with manual transmissions may exhibit poor acceleration from start
characteristics or may stall during deceleration. To address these concerns, your GMC Thick dealer can install some recently developed enhancements
which will improve the overall driving pleasure of your vehicle. These enhancements will be installed at no charge to you.
Instructions for performing this service have been sent to your GMC Truck dealer. Please contact your dealer to arrange a convenient service
appointment. Please be prepared to describe the specific concern or symptom your vehicle exhibits. This will assist the dealer in accurately assessing the
situation. Since some of the required parts are unique to your specific vehicle, a short first visit to the dealer may be necessary to determine the
appropriate parts needed for your vehicle. On the second visit, the new parts will be installed an may require between 1 to 6 hours to install, depending
on the repairs required.
We've also enclosed a brochure which describes some of the features of the 6.5L Diesel Engine and how it differs from diesel engines that utilize
mechanical injection systems. Please take the time to read this important information.
The enclosed postage paid owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction
to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please furnish us the complete name and address of the person you
sold or traded your vehicle to and return the card to us.
We sincerely regret the inconvenience or concern this situation may cause you. Your satisfaction with GMC products is of utmost concern to us. We
have taken this action to ensure your GMC Truck provides years of pleasurable driving experience.
