Some owners of 2014 and prior GM passenger cars and light-duty trucks may comment that the vehicle is experiencing a noise or fluid leak from the power steering pump, gear or high pressure side power steering hose during extremely low outdoor temperatures.
During temperatures of –22 degrees Fahrenheit or lower, the power steering fluid may thicken and the power steering system pressures may rise, potentially causing noise or damage to various components.
To resolve this condition, replace any damaged power steering system components, flush the power steering system and refill with Cold Climate power steering fluid.
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.
