    No Power Steering.

    Hi, before I start, just to wish everyone a Happy New Year!!

    Im a new member on here, so Hello everyone

    I own a Zafira A 1999. Yesterday, the power steering failed , I suspect it to be the pump, I have the square type pump, is there an easy way to remove this? as my Haynes manual says I have to remove the subframe etc.
    Or if someone else has had the same problem, and it wasnt the pump, maybe they could point me in the right direction. Any help would be greatly appreciated. Cheers Den.

    Welcome Den

    First thing to look at is if the battery is being charged. Simple way of doing it is with a voltmeter otherwise make sure you get the battery light on when you first switch the ignition on and then it goes out when started

    Thats a little high but should be ok

    Apart from checking the large fuses under the bonnet along with the ones under the dash and of course the power steering fluid I can't offer anymore help

    id remove the fuse for the PAS pump - its the purple one with the purple plastic housing

    once the fuse has been removed u can pull the purple part of the housing upwards and off the fusebox

    the purple part is attached to the positive side of the pas pump and u can then attach a 12v feed directly to it to see if it comes to life

    heres a pic of a mk4 pump albeit the TRW Gen2 pump, as opposed to the Delphi unit which it sounds like u have.



    you can see the purple part i mean

    if it works then ur looking for another cause, i suspect its the alternator over charging (equally as bad as undercharging) and as a result its automatically cut the feed to the PAS pump as a matter of course

    the above test should prove if the pump works or not, then if so, i would have the alternator checked out/replaced

    pump can be removed from the top but from experience id always do it from below

    if u have access to an engine hoist to take the weight of block/box from top then removing the subframe is by far the best way.... the ones ive removed from the top were on the mk4 8v engine which were by far so much easier than the 16v not to mention the cramped bay of the Zaf!!!

    Therefore subframe off is really the only way!

    Right, I have just noticed that when I turn the engine off, there is a rather loud rumbling noise coming from the power steering pump. Does this mean the pump is at fault then?
