    Default Cleaning sunroof drains

    Does anyone know how to clean/unblock a Disco 2's sunroof drains please?

    Having driven through some rain recently I found the floor carpet wet behind the driver seat (where rear passenger feet would go on the right hand side of the car)

    TIA

    Are the disco 1 and 2 systems not the same?

    only one way to do a proper job. strip the roof lining out. only takes 30 minutes.

    I've done it in the past with a blast from an air compressor............You can always try this first before stripping the roof lining.

    That is a good idea but can only work if you know where those drain pipes terminate on the Disco 2. I have looked all over but could not find them.

    Please tell me where those drain pipes (for front and rear sunnroofs) terminate?

    attached the 3 pages relevant to the sunroofs.
    speaking under correction but believe the drains are down the A pillar for the front and the C pillar for the rear.
    quite often it is worth loosening the trimming around the sunroof and follow the pipe with your hand to see exactly where it goes.

    LL describes what I always thought to be the case.........but finding the bottom of the pipes isn't necessary if you blow from the top. The tops are easy to find,

    I'ld still like to know where those pipes terminate.

    The carpets are already wet. A bit more water wont do more harm but I would also like to know where to expect the water to come out.

    if the pipes are blocked, the water will overflow onto the roof lining and find its way down the inside of the vehicle to the carpets.
    remove the roof lining and trace the pipes and tell us where they terminate.
    you could go to the trouble of dismantling the interior and finding them but would that be reasonable?

    I'm on holiday at present (away from home and my tools) and can not just remove the head liner. This is why I'm hoping to find where the drain pipes terminate - so I can try and get them unblocked for the return journey.

    I have had sun-roofs fitted to a couple of vehicles, and the guys ran the tubes down the A pillar and either the B or C pillar, (I'm afraid I can't remember which) to terminate just below cill level. Go back to the "blast compressed air in from the top" idea, and this should soon make it very obvious where the bottom end of the tubes are.

    ditto.
    they will basically be positioned in such a way that when they drain, water cannot flow back into the car and therefor the exact position where they terminate is acedemic.
    the blockage normally occurs right at the top where the pipes are attached to the sunroof and by simply removing the pipes and blowing them clean and to ensure the drainhole from the sunroof into the pipes are also clean, the problem should be resolved.
    not trying to sound bloody minded but personally think that the pipes' exit would not be of much concern unless your intention is to reverse clean from the bottom up.

    Landrover told me that the pipes run down the pillars next to the windscreen for the front sunroof and down both pillars behind the drivers door for the back sunroof. I have a leak on the front sunroof so need to remove lining next year.

    That is precisely my intention. That is why I want to know where they TERMINATE.

    Knowing where they run along does not help me either since that still does not tell me where EXACTLY the end points are.

    I'm on holiday, I have no tools other than a leatherman and can not remove the headlining. If I could get to the entry points there would be no need to find the termination points.

    Put air on it, it is unlikely both will be blocked, the sound of air exiting either side of the car will ID point of termination, and who knows, maybe resolve your problem in the process.
    Cannot understand why clean from bottom up and fight gravity as well as blockage, specific reason for this ?

    That presumes one can get to the entry points. I looked and seems impossible. Also if I COULD get to the entry points there would most likely be no need to find the termination points.

    As stated above, it seems impossible to get to the entry points from above the car and removing the head lining now while I'm on holiday is also not possible. That is why knowing where the drain pipes end (not where they run) seems to offer the only hope of sorting them out, either by running compressed air up them or running a thin wire up them.

    Looks like I will have to tape the sunroofs up until I can tend to them...

    taping up the offending sunroof/s sound like a good idea.
    ideally you want to get to the fitting where the pipe attaches to the sunroof from below the roof lining.
    just concerned that if you were to blow air up the pipe, the fitting may jump off.

    I know this discussion is regarding the D2 but i recently stripped my head liner on my D1 due to broken or blocked drain pipes. The front left pipe had a self taping screw going through the pipe. I fixed that, and then used pressured air to clean out the pipes. I even tried to run some wire down the pipes to clear blockage. Problem is there the end of the wire didn't come out the end of the pipe. On the D1 it seems the drain pipes run in the chassis.
    Anyways me 2 cents regarding this thread would be best to strip and fix the problem correctly.

    Gud day, any suggestions where I can find the metal attachment that the rubber hose connects. Preferably in Cape Town area. Click image for larger version.

    Let me check my spares,I may have one, but they are a very soft plastic, not metal.
