I have air in the Power Steering fluid followed with a loud irritating whinning. A little more extream than the usual noise when you need power steering fluid. How do I check for the air leak? I have yet to work on this car. I do not have an owners manual it was bought used. Where is the Power Steering line in this car? Once the air leak is found Is it an easy home repair or, should I have it professionally repaired. I have been told you to try lupus power steering leak repair but it is not leaking fluid it is taking on air?

Any advice will be greatly appreciated.
Thanks

I ment to say 2002 cavalier sorry about that I posted it before I caught that. I wonder what the 2020 cavalier's will look like. ha ha :)

Power steering systems will purge themselves of air on their own. Just make sure the power steering pump is filled up properly, as shown on the dipstick.

Then, with the engine running in Park, turn the steering wheel all the way left, then right, etc. After at most a minute any air will be purged. If the pump still is making noise, it probably is defective/broken/worn out.

Did you just buy this car? Usually pumps last a long time. In my experience, noisy pumps are often due to someone someone running the engine without adequate fluid in the power steering pump for a reasonable length of time.

No I have had it a while In fact in now has 150000 miles on it. Sounds like I need to replace the pump... Damn. The mecanic at the shop wanted to run a digagnostic. I didn't want to pay just to find out what is wrong. It has been making that noise off an on for a few weeks now. It just last week got bad.
I have fixed all my other cars on my own using advise and google without much trouble(exept the craked head). The power steering is just a little to important for me to mess it up. Is it hard to replace on your own? I just paid this car off. LOL Thank you very very much for your advise.

difficulty of replacement varies between the engines. I can't remember for sure where it is on the 2.2 OHV, but if you've got the 2.4 DOHC it's really easy, just two hoses, two bolts, and you're done.

You might try flushing the power steeriung fluid before you replace the pump, you'll want to flush it anyway, or it will take out the new pump (and you may get lucky and that may fix it). The inside of the hoses deteriorate and flake off and the pressure compacts it into a sand-like powder... just one more reason to change ALL fluids, especially the unfiltered ones :2cents:
