2008 Tahoe power steering fluid change

[ridewot]

I have a 2008 Tahoe 5.3 and 125,000 miles. I think the power steering fluid never been changed. I guess the best way to just suck out what I can get from the reservoir and add new and then run it for a while and suck it out again? Anyone have any other suggestion?

Do that. You won't get it all, but 90% fresh is better than old stuff. And then when you do it again in a year, along with your AT fluid, you'll be kosher.

I recommend investing in one of these for DYI fluid exchanges.

my yukon has electric steering but for my car that I'm very ******* ps fluid. track days and higher ratio steering mods beats fluid up. I use this method. it's easier than it looks on the video once you do it. fully flushes the system.

I use one of those hand operated $15 transfer pumps found at almost any auto parts store or harbor freight.
then I just jack up the front end just enough to barely lift the front wheels off the ground, pump out as much as I can from the reservoir, then refill with fresh fluid, start it up, turn the wheels lock-to-lock several times, shut it off and repeat. 1st time it took about 1 gallon to get it back to really nice clear fluid. now I do this annually and it only take about 3 quarts.
I do it this way so I do not have to disconnect any fittings or hoses that have not been touched in 10+ years and are basically hermetically sealed.
easy-peasy

a gal? that feels like a huge waste of fluid wow. you might want to consider just popping off the return line after sucking the res dry. no mess and it flushes the full system by turning left and right in less than a qt.

Naw, I just buy the fluid off of amazon and do it once a year, it only took 4 bottles the 1st time because it had never been done when I got my hands on it.
I am kinda rough on vehicles so others could probably get away with doing it less often. it's mostly mineral oil so it does get sort of burnt after a while, mine turns a very dark brown color and the new fluid is very light brown and more opaque looking.
