# POWER STEERING LINE CONNECTION FITTING LEAK - SEAL DAMAGE

#### Models Affected: All

"O" ring type seal fittings have been used on rack and pinion and integral gear power steering hose line connections since 1980.

Fitting torque specification is 27 N.m (20 lbs.ft.). If a leak is experienced at the fitting area when properaly tightened, this condition may be caused by a damaged fitting "O" ring. Inspect the "O" ring for damage, pipe end for cracks, fitting threads for damage and replace as required.

DO NOT EXCEED fitting torque specification. Additional torque will not increase "O" ring sealing ability and may result in cracking the connection boss on aluminum gear housings. If a leak is experienced at the comection area with a new undamaged "O" ring under correct torque, inspect housing boss for possible porosity. A porosity condition will require housing or short gear replacement.

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.
