DIESEL WATER PUMP GASKET LEAK IMPROPER SEALING

A COOLANT LEAK ON THE BOTTOM SIDE OF THE WATER PUMP ON A 1982 OR 1983 'G' MODEL MAY BE CAUSED BY IMPROPER SEALING OF THE WATER PUMP TO FRONT COVER GASEKT. THIS CONDITION MAY BE CORECTED BY REMOVING THE WATER PUMP AND GASEKT AND REWORKING THE GASKET AS SHOWN IN FIGURE 1. IF THE GASKET IS DAMAGED DURING WATER PUMP REMOVAL A NEW GASKET CAN BE REWORKED.

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.
