Power Steering Pressure Hose

Hi everybody,

my power steering pressure hose decided to dump power steering fluid on the road today. It seems both side may have had leaks for some time and today with the heat it decided to give up the ghost. It's part no. 944-347-447-02-M20

I'm a good enthusiastic 'amature and imature' mechanic who wants to have a go at replacing the hose myself. Firstly (a) I can't find any of the hoses online in the UK (lots of options in the US), so why is that? and (b) how hard is the replacement of this part?

 
Try 945 347 447 02. According to the PET that is the RHD equivalent to the part number you provided.
 
Well spotted. I forgot I was looking at the items on american sites! glad I didn't order it just yet.
 
also worth taking the old ones to your local Pirtek branch - they can probably make you up the hoses for much less.


 
Porsche want £193 for the part. Will try berlyn then pirtek I think.

So has anybody done the job themselves?
 
Did mine after buying the car last year, both res to pump hose and pump to rack hose. Easy enough job if a little messy. As long as you can get the car up enough to be comfortable under there you'll be fine.

PS - I had mine sorted by Pirtek in Wigan cos I felt it was a ridiculously overpriced part. It's been on for 12 months now and has been fine. Good bunch of guys in there, and I think it cost me £50 in total, well worth it - quality repair !
 
that's good to know mike. I might pop mine off later and pop it down to pirtek. There is one only about 15 minutes from me in gatwick.
 
Wow! have to say I am amazed at how easy it was to remove the part for replacement. Only needed a size 10 spanner and a 19mm ratchet. A bit messy with the power steering fluid but managed to clean everything and waxoil a few bits as well. The part is now in with Pirtek and a new hose should be with me by friday. Sadly it means I have to drive round in my elise for a few days (hard life)

I have a question I wonder if somebody can answer (please)

What are the torque settings for the nuts when replacing the pressure hose or if possible where can I find the information? Don't want to overtighten the nuts as they are crucial to the workings of the power steering.

 
Correct torque = nip it up, check for leaks, if it leaks then nip it up a bit more and repeat till dry [:D]

It's more of a feel thing. Don't forget you can always tighten it a little more etc. but you can't undo a stripped thread. It's more important to have some nice new copper washers in there either side of the banjo bolts, that way you won't have to overdo the tightening to get them to seal effectively.

thanks mike

you've been an absolute star with this. Your post gave me the confidence to tackle it and I had the hose out in under 30 minutes and off to pirtek within the hour. First time I've done anything from under the car and I am amazed how much space there is in there compared to my elise and my old elan. It's so easy to work under (but far more fun to drive!)
 
Mine is also doing this at the moment!

I bought on on ebay for 70 quid

How easy are they to replace?
 
Did you buy it second hand off ebay or was that brand new? If brand new that's amazing. I'm having mine made by Pirtek and they are charging £58 which I thought was amazing.

Very easy to replace.

Take off the undertray (5-6 bolts)
Remove end of hose attached to the power steering pump (have somthing handy to catch the fluid or you'll need a change of clothes and a good driveway cleaner)
Remove the end of the hose going into the steering arm (make sure you know how the washers come out as they should be replaced with new ones)
remove the clamp holding the pipe in place along the steering arm

reverse to fit.. not knowing what I was doing and it only took 30 mins to do (included cleaning everything underneath at the same time).

Whislt the car is off the road I'm waxoiling it underneath and changing the anti roll bar bushes.

While you are doing it take out the drivers side arch liner and waxoyl the brake lines behind it especially the ABS unit and pipework and also the passenger side and clean off and rust treat/waxoyl the lower wing edges as they rot there.
 
No worries Neil, glad you felt happy enough to tackle it - as you say it's not that bad a job once you get into it. Threading the new one back through can be a pain cos of the bends in the end of the pipe, but if you've come this far it won't cause you a problem [;)] as you say, generally there's plenty of room to work on these, apart from when you try to change your engine oil filter ! haha

Just on this note about replacing the washers

What sort of washers are they and were can they be purchased?

I just wanna have everything ready for when I attempt this on Saturday!
 
Copper washers that sit either side of the banjo bolts on the pipe. They should have come with the pipe if it's new ? You'll be able to get them from the likes of Pirtek etc. or possibly some good motor factors (may be able to pick what you need from an assorted box ?)

Mike
 
No I think that looks right from memory (it has been 12 months though, so don't quote me on it ! haha)

You'll see what copper washers we're on about when you disassemble it all (be careful to see where they come from). Just replace with new. OPC should have them in stock if nowhere else has, but I'd just find any local hydraulic hose repair/manufacturer who'll have a selection so you can just pick out the right size you need.

Mike
 
Pete, that is the right part (although it looks different from the original I took off), you may need to slightly bend the end that goes into the steering rack. Just be careful you don't kink it.

If you have a pirtek or similar around you it is worth getting new banjo bolts and washers. I fitted mine this evening and found it much easier with everything nice and new. Have to say the bill from pirtek came back slightly higher than the estimate, but I have a work of art on the car now as they completely rebuilt the U bend in the system and it's been over machined compared to what you really would need. I'll take a photo shortly and stick it up, but essentially they made a brand new one for £65 so well chuffed. I found the steering to be lighter than I've ever known it so the leak has probably been there alot longer than my ownership (14 months).

Have waxoiled the brake lines as suggested and done some of the chassis that is visible, but I am pleased that the car is in great condition underneath!
