SPECIAL COVERAGE
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
to be ordered from CCA using the normal ordering procedures. Please discard all copies of bulletin
00064G.
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.
