When sending a diesel engine injection pump to a Roosa Master Agency for repair, it is extremely important to be sure the condition being experienced is listed. Without this information, it is virtually impossible to make proper repairs. The warranty claim form (Buick 7221) must be filled out and accompany the injection pump when warranty repairs are requested. It is suggested that this form also be used for out of warranty repairs, as it contains all the information needed to effect a repair. Complete and detailed information about the condition being experienced will help insure proper injection pump repairs.
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
