Condition
Some customers may comment that their vehicle is 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.
Cause
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.
Instructions
To resolve this condition, replace any damaged power steering system components, flush the power steering system and refill with Cold Climate power steering
fluid. Refer to Power Steering in SI.
Note: In some extreme operating conditions, this fluid may not correct the condition. An alternate power steering fluid is available for a select group of vehicles,

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.
