Power Steering Fluid Change

Recommended Posts

Ive tried to find a thread on this but cant seem to find it..Need to change P/S fluid, its getting sort of gummy but need to know how to drain it or do you suck it out with something?? Also what type fluid should I use, also is there a filter inside the reservoir??? Thanks in advance, Stroker

I just did the dilution method....suck out what's in the reservoir, refill it, start the engine and turn the steering whell lock to lock a few times, stop the engine......repeat.

Using an Excel spreadsheet calculator (I found at http://www.bobistheoilguy.com/) I figured after doing the suck/refill about 10 times, about 90% of the fluid is now "new".

It took about an hour, but was far less messy than removing the return hose and trying to pour fresh fluid into the reservoir at the same time.

Using an oil bottle pump is definitely better than using a baster.

I just did the "suck and fill" of the power steering reservoir as well, except I kept the engine running the whole time. My understanding is that when the engine is running, power steering fluid is flowing through the reservoir constantly. I used approximately one quart of Toyota T-4 AFT. I stopped after 5 or 6 times (of suck and fill) when the fluid became pink and clean.
