SUBJECT:
Special Coverage Adjustment – Electronic Diesel-Fuel Injection Pump Failure

– Repair/Replace
MODELS:
1994-2002 Chevrolet and GMC C/K, G and P Model Trucks; and 1997-1998 B7

School Bus Chassis, Equipped with a 6.5L Diesel Engine (RPO L49 – VIN Code

P; RPO L56 – VIN Code S; L65 – VIN Code F)
This bulletin is being revised to remove the diesel injection pump from part restriction. Pumps are

CONDITION

Some 1994-2002 Chevrolet and GMC C/K, G and P model trucks; and 1997-1998 B7 school bus

chassis, equipped with a 6.5L diesel engine (RPO L49-VIN Code P; RPO L56-VIN Code S; or RPO

L65-Vin Code F), may experience a failure of the electronic diesel fuel injection pump.

SPECIAL COVERAGE ADJUSTMENT

This special coverage covers the condition described above for a period of eleven (11) years or

120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed

in service, regardless of ownership. Damage from poor quality or incorrect grade diesel fuel, and

gasoline or water contamination, is not covered under the terms of the 6.5L diesel warranty.

This special policy applies ONLY to electronic diesel-fuel injection pump repairs and/or replacement

as a result of injection pump failure. The pump repair or replacement will be made at no charge

to the owner. This Special Coverage does not cover: glow plugs, turbocharger wear, low

compression engines or PCM/PCM wiring conditions.

Fuel quality may cause driveability problems such as hesitation, lack of power, stall, no start, etc.

For best results, use Number 2-D diesel fuel year-round (above and below freezing conditions) as

oil companies blend Number 2-D fuel to address climate differences. Number 1-D diesel fuel may

be used in very cold temperatures (when it stays below -18°C (0°F); however, it will produce power

and fuel economy loss. The use of Number 1-d fuel in warm or hot climates may result in stalling,

poor starting when the engine is hot and may damage the fuel injection system. For further detail

related to Fuel System Specifications, refer to SI.
