Power steering systems use a hydraulic pump, which is driven by a belt, to assist with turning and steering the vehicle. The fluid is released and applied to the steering system any time the wheel is turned, which triggers a decrease in the system's pressure. On the 2006 Pontiac G6, only the V6 models have hydraulically assisted power steering. The power steering fluid should be checked at every service interval.
Make sure the engine is cool. Locate the power steering reservoir. On the 2006 G6, it is mounted to the power steering pump near the alternator.
Remove the dipstick from the reservoir. The fluid level should be in the cross-hatched area of the dipstick.
Add small amount of power steering fluid until the level is correct. Do not overfill the reservoir. If too much fluid is added, remove the excess.
