. power steering flush using vacuum pump.

if you have vacuum pump you can use it to flush/change steering fluid in your car. you will need 2 L of fluid ( I use Pentosin/FUCS 202.), plug of some sort to plug return line connection and a means to connect vacuum pump to the return hose. that is it.
First suck all fluid from reservoir, there is going to be about a finger of fluid left on the bottom due to mesh on the bottom of the reservoir. unscrew bolt holding windscreen washer fluid reservoir so to gain some space when removing return pipe on the bottom of fluid reservoir. (smaller of the two hoses is return). use pliers to move spring clip down the hose and remove hose. put cap on the nipple, fill reservoir with fluid, connect vacuum to the rubber hose and watch fluid go down. keep adding fluid as needed. when you see clear fluid coming out you are done.
unplug vacuum, take plug off the reservoir (use finger to stop fluid from escaping) and reattach return hose. fill reservoir to the mark and that is it. start the car, turn steering wheel full left to full right

Nino as I said before you're impressively equipped for anything.
And you document everything for others to learn from.
I nominate you for member of the year!

Can I bring mine to you?
You should start a business!

Looks great and a wiki entry right there?

With air box out = planty of space to take out power stearing reservoar for cleaning.

Nice writeup

Just a quick point is you mention brake fluid to clean, and what you mean is brake cleaner aerosol. (as in the pic)
Somebody else might take the text literally without thinking!

Thanks, good point, corrected

Can PAS fluid be changed by just siphoning off the reservoir multiple times over a few days then topping up/lock to lock every time it's siphoned off? I don't have the skills to replicate Nino  Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Yes, I have done that successfully on my TDV8 and my Volvo. I used a large syringe with a bit of pipe to suck the fluid out of the reservoir, filled reservoir with new fluid, then used the car for a bit to circulate fluid, then repeated until fluid was clear. I did this over a few days.

Won't be as clean as nino's efforts though  .
Experience is the only genuine knowledge, but as time passes, I have forgotten more than I can remember

Rob,
How much fluid should I buy ? and how many times did you suck and refill ?

I have never changed mine before on all 4 I have owned, so I am all ears to any advice / tips.

I do the same work, but littlebit differently.
Everithing was the same as Nino doing until the vacuum pump. I didnt use it. I lift up both front wheels and turn the steering wheel from left end to right end couple times. During turning old oil just come out from the return line and new go in same way as Nino-s.
By doing so you can be sure that steering gear is also compleatly empty from old oil.
NB: remember not to start the engine during that procedure! Only ignition (to unlock the steering wheel)!

That's almost true, except that engine must be indeed running to flush the system completely. 4l new fluid is needed for that. And attention is needed not to let the fluid level in reservoir get too low while flushing, because with engine running the pump is moving this fluid really fast!

Quote from 4.4 TDV8 workshop manual:

Flush the power steering system.
9.
Start the engine
With assistance turn the steering slowly lock to lock 3 times at approximately 1 revolution every 5
seconds.
Continue to flush the power steering system until 4 liters of power steering fluid has been added to the
power steering reservoir. This should take approximately 30 seconds.

Thatwhy I didnt start the engine, to avoid get air in system. It suck oil really fast.
I dont see any reason why need to start the engine (maybe if not lift wheels up from the ground). Oil go anyway through the oil pump, is it running or not.

And I add that the inner diameter of the return hose is 10mm if someone is preparing for the job.
