Condition
Some customers may comment about a whine or growl noise from the engine compartment for a few seconds after starting their vehicle at low ambient temperatures (approximately -12°C (10°F) and lower).
Cause
In cold ambient temperatures, the power steering fluid thickens. The thickened oil may cause the pump to be noisy during cold start-up.
Correction
Important:
DO NOT replace the power steering pump for this concern.
Change the power steering fluid to cold climate power steering fluid.
Refer to Power Steering System Flushing and Power Steering System Bleeding in SI.
