WASHER BOTTLE CRACKING (SERVICE PROCEDURE). GMC Truck S15 Pickup - 2WD 1990

For 1990-2009 cars

# WASHER BOTTLE CRACKING (SERVICE PROCEDURE)

MODEL: 1988 - 1991 S/T TRUCKS

Some 1988 - 1991 S/T trucks may be experiencing a condition of windshield wiper washer bottles cracking and then leaking washer fluid. This condition can be caused by an increased amount of pressure exerted by the two fastening nuts and screws. This increase in pressure causes the screws to cut into the plastic and initiate cracks.

To correct the situation new parts have been released with a wider flange, and the torque requirement has also been revised. The new torque requirement is now 5-8 N-m (3.7 - 5.9 ft. lb.) instead of the old 8-11 N-m (5.9 - 8.1 ft. lb.). When ordering a new washer bottle be sure and order new bolts and nuts with the revised flanges.

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.
