Condition
Some customers may comment on a fluid leak. Upon investigation, the technician may find that
the power steering cooler pipe/hose assmbly is either split or leaking around the clamps. The
leak generally occurs during cold start conditions.
Cause
The cause of this leak may be due to the higher pressures generated in cold temperatures.
These pressures may exceed the strength of the hose or clamps.
Correction
Use the appropriate repair procedure below based on the engine application of the vehicle being
serviced.
V6 Engines
The hose section (1) where the leak can occur is shown above. On V6 applications, the hose
fittings are constant tension clamps, therefore, the hose and clamps can be replaced. Use the

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these 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 your GM dealer for information on whether your vehicle may benefit from the
information.
