Hey before you take it to a mechanic shop if you could drain off some of the powersteering fluid with a suction device and add some Lucas powersteering additive this would probably take care of it in time.. after some driving .. would save you alot of $$ Lucas is best for this problem.. just use a suction device stick it down in the powersteering pump hole where you check the fluid and **** out as much as you can then add the lucas to fill back up and drive a few days and presto.

It may be the air pump. There is a small electric pump that pushes fresh air into the catalytic converter to keep the emissions in check before the car warms up. The gm part is an AC Delco made in China part that breaks quite often.

SOURCE: Can someone tell me what that whining noise I hear

Can't really do better than a guess ...noises I can't hear aren't my specialty. It could be the bearing in the front of the alternator...when you first start up the alternator is loaded, as it puts power back to the battery that you just used when starting. You hear it more in the AM because you are standing still, the engine is cold and needs more power to start than when warmed up, and the battery has lost some power keeping clock etc going all night. During daytimnes starts the length of timne it needs to do this is shorter and requires less demand. (long explanation for a guess!!!) Either way should not be anything horrible! Trans may also be low on fluid.
good luck

I had the same noise on my wife`s 03 cts. It was the the rubber bushing on the shifting arm from the shift lever to the trans. The arm was 250.00 plus I installed myself. Very easy to get to. Bad design should not have went bad.

Where do I pour the power Steering Fluid?


Pull up on the engine cover. It should pop off with slight force. The power steering fluid reservoir is under it.
