DIESEL CYLINDER HEAD REPLACE 5.7L GOODWRENCH W/DOWEL PIN

Two (2) new cylinder heads have been released for service for the GM Goodwrench 350 diesel engine. The new cylinder heads, P/N 22523637 and 22523638, have different dowel pin locations than cylinder heads previously released. Previously released cylinder heads may be used on the GM Good- wrench diesel engine by changing the dowel pin locations in the block to agree with the holes in the head. DO NOT install heads without the dowel pins.

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.
