DIESEL WATER PUMP LEAK GASKET INFORMATION

MODELS AFFECTED: 1978 TO PRESENT - ALL MODELS

There are two raised sections on the front cover between the bolts underneath the water inlet holes. The raised sections are put there to put a higher load on the water pump gasket in that area. Should you experience a leak in that area when transferring the water pump to a Goodwrench engine, apply an RTV sealer to each side of the gasket. Do not grind off the raised section.

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.
