    Default Leaking GS Suspension

    Hi, I have a 1972 Citroen GS and I noticed that after parking it up for a few weeks, when I returned to the car it was right down on its suspension. When I raised the bonnet I noticed that the LHM fluid had leaked out somewhere near the top of the LHM reservoir. Starting the car did not raise the suspension and of course no brakes either. I am in Melbourne on the Mornington Peninsula. Any tips as to the issue or where to get it fixed and what I could expect to pay? Thanks Mark

    If it won't raise the car you would assume that it has lost most of the LHM. Was the puddle under the car a lake or just a spot?

    Not really a pond, there was just a leak at the top of the reservoir so it was pooled at the top, no leaks underneath. But I looked again this week and there was more oil underneath the front. Any suggestions?

    Tricky to offer help without knowing more about the car and your own experience with Citroen hydraulics. . .

    The car will drop to it's bump stops after being left for an extended period, in this position you may find LHM on the top of the reservoir if it has been overfilled. So far, all normal. Check the level indicator to see that there is LHM in the tank.

    Why is the car not rising?? Is the height lever in the low position? If so move it to the centre position. I can't see how it wouldn't be, but check the bleed screw 12mm? on the accumulator is closed off (not too tight, just nipped up).

    We need to get the car rising before we go looking for possible leaks. Be aware that after a week of non use the suspension may take a while to pressurise and lift the car, a little throttle will speed up the process.

    Over to you

    Cheers

    It's also possible the main suction hose has a split and is admitting air. That happened on my CX. The boot at the pump is also a bit of a problem child. If GSBaby needs it, I think I do have an NOS suction hose I'll just give for the cost of postage.

    GSBaby - not sure how you got on with your leaking suspension. I've completed two GS restos and finding my way with the marque.

    I am in the Mornington area this weekend. Will PM you.
