2006 c5 lds capacity?

[Stekelly]

Quick one this time. The rubber hose going from the front passenger side strut to the steel pipe in the wheel arch broke at the jubilee clip and emptied the contents on to the ground. I've cut it and reconnected. So the question is, how much lds is in the system?

As a secondary, the hose is tight now if the car is on a jack and the wheel is hanging fully down, are these replaceable or is the other end made in to the strut.if its jot easily replaceable i think I'll get a joiner and extend it a bit.


Cheers

Rooting on eBay. Is it the leak off hose that I'm looking at?

Sounds like the leak off hose. Same part going right back to the BX! Citroen want £20 for it these days though... new clip required as well. Think LDS is about 5 litres.

Sounds like the leak off to me yes. Not sure of the actual capacity, but I would top up according to the level checking procedure anyway rather than adding a set amount since I believe these can suffer from damaged tanks if overfilled. If it's lost a lot then I'd probably buy a 5 litre can anyway & any left over will be there for future use. Further than this I can't advise I'm afraid as I only know the procedure for green blood levels, not orange. No doubt someone will chip in with the right way to check the level if you don't have a handbook, errr... handy!

EDIT- wow £20 seems a lot, doesn't it include the clip with it?

The simple procedure is to lower the suspension to it lowest setting, and then turn off the engine. Take off the plastic cover on the driver side of the engine bay, and you will see (amongst other things) the LDS reservoir. Take the cap off, and you will see that there are 'gratings' in the 'filter' of the tank. There are a couple of levels within (vertical slots), and the LDS should be between these levels. I have linked to an image showing these indicators;

This has been my first post xantia citroen, so feeling my way with regard lds.its a battered old ex taxi so just a cheap runaround for work for a bit. I'll eventually get a nice example.

I think I've lost as much lds as is possible to lose so 5 litres is probably the way to go.

If you find that the suspension will not rise it is because the pump will not 'self prime'. If this happens what you can do (according to citroenxm, a forum member) is to thoroughly clean around where the cap goes, and then blow hard into the reservoir. It only takes around 7PSI to prim the pump and get it working.

I personally intend to make a simple 'pump cap'. I have an LDS cap, a tyre valve and a cycle pump. One of these days I will fit the valve to the cap, and then I can (if required) prime the pump.

Cheers. Help is much appreciated.

1 other question. I assume the leak back pipe is not under pressure of any significant amount? I could fill the system and have the car back running tonight but I've ordered a new hose on ebay , can I swap them when it comes without losing all my lds again?

[ekjdm14]

I'd incorporate a gauge into that arrangement if I were you, if what I've heard about split LDS tanks is in any way true. I'd imagine 7psi is quite a bit for a plastic tank to hold, although I wonder if you mean 0.7 since it also seems a helluva lot of pressure for one to blow into the tank "manually"... I seem to recall from my younger/bored moments I could barely make the needle move on a low-range gauge for motorcycle forks

The leak off pipe shouldn't be under pressure I don't think, if it's the same part carried over from earlier HPN Citroens then I would imagine the functional pressure to be unchanged too and the ones on our XM were short too & just pushed on to the rigid pipe with no clip. Not ideal, but shows there wasn't much pressure there at least.

With the engine/pump off there should be virtually no flow from the pipe so you should be able to change it without significant loss

[Hell Razor5543]

I belive (but I am NOT certain) that 1/2BAR is required to pressurise the LDS system enough to allow the pump to get going (assuming that there is now air in the pipes, as could occur after a leak, or when the system has been drained). As there is 14.7PSI to 1BAR (and most people know PSI) I just switched over to PSI.

[RichardW]

Yep, 7psi is right for a MK2 - not sure about a MK3.

Yes you can change the leak off hose without losing the LDS. You need a pair of Clic pliers to open / close the clip.

[Hell Razor5543]

Just to let you know, the valve in the cap is simply a flexible washer, that will allow passage from the outside of the cap to the inside, but will seal against air (and other things) from passing from inside the cap outwards. I just popped the washer off my spare cap to investigate.

[ekjdm14]

Well, you learn something new every day. So I would suggest that Paul (citroenxm) either got lucky with priming his pump, or he has HUMONGOUS lungs!

I'd agree there's likely air in the pump if it totally drained the system so probably needs priming, if so what does anyone think to incorporating a gauge in the pressurising arrangement to avoid overblowing/splitting the LDS tank? Worthwhile, or just pump with engine running until you hear/feel the pump start to pull fluid?

[myglaren]

Should be no need to run the engine. Pump should run to adjust height anyway - sitting on the rear bumper should be enough.

But - and a big but - priming should be done or at least attempted with the pump fuse pulled as running it dry could well damage it.

[Stekelly]

One other thing. The rear was dropping all the time(very quickly, couple of mins) before the fluid loss. Is that likely to be anything simple or something big like knackered rear struts or something ?

I've access to a donor car (that doesn't sink) and ramps, tools etc so if it's anything handy enough I'll do it.
