#### Models Affected: 1985 Somerset Regal With 2.5L Engine (Engine Code U)

#### NOTE: Additional Information for Buick Bulletin 85-6B-5 dated June, 1985.

Inspection of returned parts has indicated that some technicians may be using methods other than those specified in the service manuals to remove and install water pump pulleys on the above engine.

Pulleys should be removed with tools J25034-B or J29785-A only and should be installed using tool J25033-B.

Use of an arbour press on the water pump will dislocate the pump shaft causing internal damage and seal leaks.

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.
