Is the power steering fluid in the reservoir suppose to turn and rise slightly like if it were in a blender?
That is what mine is doing. I just replaced the reservoir thinking it was a dirty screen problem but it is doing the same thing with fresh fluid and new reservoir.

 

What is the same thing?

 

The fluid rises and turns in the reservoir like if it were in a blender. My question is, is that motion inside the reservoir normal?

 

its called cavitation and yes. Are u experiencing
a noise like air in the line?

 

No noises, but I just looked at 2010 Caravan with a 3.3 liter engine and the fluid does not rise above the fill line like mine does. My fluid rises a good inch over the fill line of the reservior. When I shut her off the fluid goes back down to it's normal level. Something just isn't right.

 

Maybe not. 2007 was the last model year in the 4th generation line. A 2010 is the third year of the 5th generation line. You may be comparing apples to oranges. Try to find a 4th gen model (01-07) and probably better off with an 05 and up.

 

you may have air in the line

 

I've bled the system, but it continues to cavitate. Please check out my video; it's kind of hard to see the fluid but there is one scene where you can see just how high it gets in the reservoir.

 

add fluid to above the fill line it will stop the cavitation.

 

How much above? I am afraid it will seep out of the cap.
