2006 Ford Taurus air bubbles in power steering

Post by HSV-Taurus » Wed Jan 08, 2020 7:37 pm

I have a 2006 Ford Taurus. I have air bubbles/foaming of the power steering fluid. I vacuum bled the air out but still had problems.

I replaced the pump thinking that may be it but still have issues with air. I vacuum bled several times.

Also another weird issue... I fill up the reservoir to the proper level then start the car. The level goes down considerably. If I put in fluid while running it is obviously too much and overflows when I turn it off.

Where should I look to next?

Is it possible that the screen in the reservoir is blown out? Saw cavitation before in my brothers ml320. Replaced the reservoir and bled the system properly wand no cavitation afterwards. I cut the old reservoir open and the screen was broken.

I bled the steering by jacking up the front wheels off the ground and turning the wheel lock to lock 20 times or so.

I think I have it now. Didn't realize it would suck in so much fluid when I first started the process. I just had to fill the reservoir almost to overflowing, with no cap, and then run it. I lifted the front with a jack to go lock to lock as you mentioned as well. I went lock to lock about 50 or 60 times before I was happy. I then adjusted the level.

Even with a high level of fluid I am surprised at how far down it goes when running.

Smart move. The jackasses that installed a new steering rack for my brother did not properly bleed the system and they blew out the screen. Read the following and loo at the pics. I am "warment" on that site as well.
