experiencing noise or a fluid leak from the power
steering pump, gear or high pressure side power
steering hose during extreme low outdoor temperature
operation.

During extremely low temperatures, -30°C (-22°F) or
lower, the power steering fluid may thicken and the
power steering system pressures may rise, potentially
causing noise or damage to various components.

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.
