Hydraulic steering pipe (FIAT Scudo 2004 2.0 JTD SX).

This is the silvery metal (and black rubber) pipe that runs from the ATF resevoir to what I assume is the power steering pump.

Mine was rather leaky, and unsurprisingly the MOT man objected fairly strongly. Pity about his nice floor.

This pipe has previously been sawn in half around where the steering rack passes under, possibly by the garage that replaced the rack (after which I had to do the job again because the recon rack was faulty; there was no need to cut the pipe!). I had hoped it would be leaking where a short piece of black rubber hose was jubilee-clipped on to join the ends, but no. The pipe (unsure what it's made of) shows evidence of considerable (galvanic?) corrosion at various points along its length, with some pitting that has gone through, and some that has nearly very gone through.

New, these are quite expensive. Since the thing has flexible rubber sections, can I replace the corroded metal part with rubber hose? If so, where can I get it, and what sort should I ask for? The OD of the metal pipe is about 12mm, measured with vernier calipers. Other options?

hey there, if the pipe connects to the fluid reservoir it will be a low pressure pipe. any low pressure pipe can be replaced with a flexible hose capable of resisting oil and standard hose clips.

the high pressure feed from pump to rack needs to be made of hosing and connections capable of withstanding high pressures. if it this pipe that has failed i recommend taking the pipe off and taking it to a hydraulic specialist like Pirtek. they charge £40 for a basic hose with 2x crimped ends. many people thing that the hose needs to have the steel bits in the hose however the hose can be replaced outright with a continues flexible type so long as it is secured from chaffing on things. i just hope the connections are standard.

Thank you.

The OD of the metal pipe is 12mm. What sort of hose should I ask for? Is a motor factor likely to have something suitable?

Edit: As above, where the metal pipe had previously been cut, it was joined with a short piece of rubber hose held on by 4 Jubilee clips.

Right. The metal pipe is made from some sort of aluminium alloy, at least it smells like that when you rub it, it looks like that, and it's very soft. I am not sure that it was cut, it may have snapped and been repaired with about 4" of rubber tube.

Anyway, I got a metre of 10mm fuel hose (£6, Halfords of all places, better price than motor factor who tried to sell me heater hose!), and Jubilee-clipped it to the short piece of pipe still attached to the steering pump (after having carefully reduced the diameter of the 12mm metal pipe and smoothed its edges, also working a tap spanner handle, about 11mm diameter, up the rubber pipe first to spread it). A bit of ATF in the rubber pipe and on the metal pipe helped it slide in. I cut the original rubber pipe coming out of the resevoir, about 3" before it enters a plastic tunnel screwed to the chassis just under and in front ot the resevoir, and fed the new pipe up through that, and joined it to the old one with a short section of "good" pipe from the original metal one.

So it's back as an hydraulic circuit, I'll get some ATF and fill it tomorrow.

MOT question: The original metal pipe was clipped to the top of the steel member running in line with the van just begind the wheel (the anti-roll bar is bolted to this. Not sure what it's called. A sub frame?). The new rubber hose follows the same sort of line, but should I think be clipped too. Is it in order to cable tie it to the steel member, or is something more enduring (galvanised wire, linked Jubilee clips, whatever) needed?

A steel cable tie would probably suffice.

Zog · 2021-12-20 12:45:19

Thank you. I will see what I can do.

Off to do the N/S CV boot now. Urgh.

Hello all.

I have a....Scudo/2006/2.0 JTD - in Blue.

and also, the same proplem as the OP.

a Leak, Hydraulic pipe, from bottle end, on the drivers side.

seems my leak is somewhere along the pipe as it runs behind the wheel, has been there some time but now requires a top up after every journey out. Time to sort it.

I have a replacement pipe on the way, said to arrive at the end of the week...but as am fitting myself, could the OP or perhaps another board member tell me where it connects (not the bottle end smile )....and will it require anything other than taking the wheel off to access the connection, or, should I be going at it from the underside ?

I have the Scudo/Dispatch/Expert manual ( the download) but see nothing that could help me there.

Thanks !

Had a look from the underside, found what I believe to be the correct Pipe connection.

...not a particularly easy area to get at, so if no response, will remove the wheel and look at it from there.

Cheers

Mine has pretty much the same problem as everyone else. I generally top the fluid up once a month. When I first got the van, the steering would whir when turning, until i topped the reservoir back up. But it's been getting gradually worse, so time to try and fix it I guess. MOT due next week, I don't see it passing, so might have to mothball the van for a couple of weeks.

Are they ever. wink

Could be worse, it could be the EGR. tongue

Yes, that looks like the boyo.

Prop the van up, get the wheel off, remove the plastic cover that stops grot spraying into the engine compartment, undo the nut, get your pipe off, replace.

I used a rubber hose from Halfrauds, 'cos the used alloy pipes I could see on eBay etc. were pitted like mine, and a new one was ££OUCH!

Candere · 2022-02-18 22:20:09

Glad you appeared Zog....Excellent news !

....didn't fancy attacking it from the underside, as "Pathfinder100", a PITA.

and Yes, have my rubber pipe replacement and will do it over the weekend.

Cheers.

Have fun. It's bloomin' windy at the mo. I could be wrong, maybe it's the drink, but it may be that I used a bit of the original rubber part of the rubber/alloy pipe at the resevoir end, and linked it to the Halfraud's pipe using a short piece of usable alloy tube from the k-nackered old tube, 'cos the new rubber would not go on the resevoir's spigot. So my setup is: pump end in unperforated alloy -> rubber hose, secured with Jubilee clips -> along the chassis and up through the plastic "tunnel clamp" (which unclips) to a short cut off section of original alloy tube, secured to the rubber hose with jubilee clips -> some original rubber hose -> the resevoir's spigot with original hose clamp. So the whole lot apart from the alloy pipe at the pump end and a bit of original rubber hose at the resevoir end is replaced bu about 990mm of Halfraud's best rubber fuel pipe which is cheaper and better than other options. I did have the idea of using microbore copper central heating tube, but the shortest length I could buy was 15 metres, and too dear.

All done...Thanks Zog.

as you can see , opted for a complete new pipe and connector.

most trouble I had was with the two alan screws holding on the plastic guard, they'd rusted with no grip, so drilled them out.
The nuts on the new pipe were larger than the original, called for a larger spanner, and in that small space, not and easy fit...so used a stubby adjustable. I got it tight from the wheel entrance, but angle is such that I decided to give it extra nip from the underside.

...will check on it after the next few journeys, but looking good.

again many thanks for the assistance/ideas - Appreciated !

All the best - C.

Hm, I could probably do with one of those, mine leaks between the reservoir and the pump

Gasp! A new pipe? At how much? I'd love to know, just in case!

Candere · 2022-07-14 01:16:15

...excuse the late reply, Pigeon went missing wink

Pipe was about 30 quid.

Cheers
