Power steering fluid change question

Hey guys,

I used the Turkey baster method to change my PS fluid today and had a question. So when I siphon out the fluid and refill it do I refill it all the way up till the reservoir is full or 1/4 to 1/2 way is good enough? I mean if the goal is to get as much as the old fluid out of the lines then filling up the reservoir just a little will imply that the lines are full correct? Or given the fact that we need to start the car to turn the steering wheel is it necessary to fill up all the way every time.

The reason I bring this up is the fluid that is refilled during the middle runs will end up getting wasted as we will siphon it out so by doing this we can have enough left for the final fill. I filled up all the way up every time and in the end barely had enough to fill it up. I know I needed to have a back up bottle but just wanted to see what is the general practice? Thanks.

Consider changing the reservoir since it is relatively cheap and contains a filter. On mine, it seemed that the old filter was contributing to re-contaminating the new fluid despite five flushes. The more new fluid you add in a multiple fill-and-drain flush, the more you dilute the old fluid still in the system. However, it's not a very efficient way to flush the fluid since there is a substantial amount contained in the rack and hoses. On most cars I would disconnect the return hose (where it connects to the reservoir) and start the engine briefly to pump out all the fluid.

Do it the right way! It is not hard.

beware the return hose from the engine.. that sucker was melted on to the res when I changed my res. I had to cut it. Luckily there was enough slack in the hose that I could mount it on the new res. But then I had to tight the crap out of my new hose clamp to get it to stop leaking. The hose clamp starting slipping I got it so tight...luckily it's not leaking anymore.
