Hi all,

2007 STi.
Looks easy enough to change the power steering fluid.

Can anyone suggest which fluid to use? I'd perhaps order from Amazon or Opie.
I will check for leaks and may do the O ring on top of the pump whilst I'm there...

Many Thanks

 

Hi ,
Dexron 111, worth doing the rubber seal it’s about 6£ from import car parts , careful when you screw the bolt back down as the aluminium pipe can be weak , the aluminium pipe needs to be properly seated first , it’s worth doing the top rubber hose to the aluminium pipe whilst you have it off , the way i changed the fluid was syringe the old stuff out , fill it work the pump , syringe out , i did that about three times till the fluid was clear , it’s surprising how dirty it was , the pipe and seal are good preventative maintenance as pumps are ££ and sometimes difficult to source 👍

 

If you're close to Milton Keynes I have about 3 litres doing nothing.
ordered 5 litres not sure how much I needed and needed practically nothing.

 

Unfortunately I won't be, but thank you very much all the same Robsy

 

I've found the Dexron 111 on Opie, is 1 litre likely to be enough for 2 or 3 flushes?

 

one should be fine , you will probably have some left over

 

Dexron lll now arrived from Opie.
Can I do this tomorrow when everything is cold, or does this need to be done after a drive when the fluid is I assume warm?

I'll be removing the old fluid with an oil vacuum that croc clips onto the battery, very good little pump from Pidl it was.

Also, can I do a few lock to locks with the front wheels on the gravel drive? I've seen a video on YouTube (Mr Subaru) and he has his Fozzie up on axle stands....I don't need to have the front wheels up surely do I ?
Thanks in advance, Matt.

 

Take it for a small drive , fine to do it when it’s cold , and i did not jack it i just did lock to lock on the drive , i emptied and re filled about three times till the fluid looked a lot cleaner it’s a very easy quick job , a bit longer if you do the seal and or pipe but be very careful how you screw the metal L shaped pipe down after

 

I was hoping you'd say that! Thanks Vxr, I couldn't see the need for raising it up instead of taking it out for a drive, but so many YT vids show them up in the air.

Pipe and O ring for another day....when spring arrives! But, will be checking closely for leaks, so could in fact be next week lol

 

I did mine with the wheels on the drive, siphoned out with a big syringe, top up, lock to lock a few times, syphon out, refill and repeat until what's coming out is the same colour as what's going in, if you do it with the engine running don't take out too much at a time as the pump needs to have something to circulate otherwise it makes nasty noises.

 

Thanks Shane, engine will be off whilst removing old fluid, but will keep it topped up to about minimum whilst flushing / engine running, then top up at the end.

I have a litre to play with, so hopefully enough - to at least flush most of the old stuff out anyway.

 

Done.

Did 3 flushes in the end. The old stuff was grubby at worst, but least it's done now.
Not been flushed in the 8 years / 70k miles since I've had the car....at least I don't think so anyway.

No funny noises, air bubbles, or leaks, so happy days.

 

Good to hear it all went well , a quick easy job often not done , as people just don’t think to do it

 

Thanks Vxr, yes, exactly, something easy, cheap and preventative is always a must.
Onto my next post....bonnet linings!

 

I thought my pump was on its way out as it was getting noisy, turns out the 17 year old fluid was past its best, it's now nice and quiet again. Also did a clutch fluid change, the Reservoir on the classic sits right above the turbo and I'd notice the clutch peddle would get really hard if sat in traffic, again I think it was the original fluid so a change of that fixed another problem.

 

Was the clutch fluid a 2 man job? How did you do it?

 

Bonnet linings 🤣 , clutch fluid on the new shapes there is a little bleed screw same set up , same as the brakes , i sucked out the old stuff and replaced , i felt that would be enough as the bleed screw did not look like it would remove much more fluid that what i had done any way
