Yes, that's the easiest method by far if the fluid in there is half-decent. There's no advantage in the PS fluid being pristine IMO.

Yeah I assumed as much I was just getting a feeler for how difficult a full flush would be.

This is old but was looking to do this for boiling issues I didn't see talked about. Mixing the fluid and not doing a full flush will bring down redlines boiling point if the stuff in there is still OEM. Not sure what the OEM boiling point is but I just wanted to bring that to light. Ill be disconnecting the bottom hose with it in a bucket, turning the wheel, and getting it all out while filling it back up if no one objects.

That's what I did since I was upgrading the PS cooler at the time, had no issues.

Thread revival, can someone do a diy for power steering flush since just draining the reservoir doesn't completely clean the lines.

Thread Revival.

Did not make a DIY, but did figure out how many siphons or drains it takes to get up to % of fluid swap you desire.

It takes one qt. to fill the entire system. So says the manual.

I can siphon .24 qt. each time.
I siphon and fill and drive to mix it thoroughly.
4 siphons in on qt. According to my spread sheet, I will only get about 58% fluid swap using 1 qt. Pointless to continue with more than a quart. Good enough for me as I do not drive my car hard.
Should be fine for at least 2 more years then I will do it again.

edit. Error is spread sheet.

At 1 qt. of siphon process I get 67% change out 2 qt. of process gets me to 89% swap.

I know is easy but im the type of person that works with pics hahahhahaha!! is just more easy :p im going to install the oil cooler soon and want to make this maintenance at the same time cause i have to remove the front bumper... soo if i have a chance i would take some pics for this thread ;)

Did anybody tried Motul multi ATF Technosynthese?
