Prior to installing an engine block heater accessory package (Part Number 12340074) on a 1988 Skylark equipped with a Quad 4 engine, it will be necessary to install a new radiator outlet pipe assembly designed to accommodate the heater. This outlet pipe is not included with the engine block heater package and must be ordered separately. The outlet pipe can be obtained from GMSPO by ordering Part Number 22535812 (automatic transaxle) or 22535813 (manual transaxle).

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.
