    Hi,

    I bought a Volvo 960 3L 24v last week and when I looked under the
    bonnet (it's overheating...but I'll come to that in another post) I
    noticed that I have a black unit which is disconnected from the
    electrics, and looks like it should have a pipe coming from it.

    I know virtually nothing about cars (I'm trying to learn fast) so I've
    no clue what it would be. What I do know is that photos of other 960s
    show the unit connected to something on top of the engine, something
    that mine doesn't have.

    Here is a picture of another 960 with the part I have, and the other
    bits that I don't have, labelled:

    I have tried to buy a Haynes manual but they don't appear to print one
    for the 960. Is there another variant which has the same engine, etc?

    Any help would be much appreciated.

    Thanks

    Simon

    The motor driven unit is the secondary air pump which pumps fresh air into
    the exhaust for upto around 30seconds at cold start to improve emissions and
    cat-light up time. The hose ducts the air to the anti-back-fire valve which
    is the silver unit ontop of the exhaust manifold.

    Thanks a lot for the reply. Is it a major problem that my car doesn't
    appear to have the anti-back-fire valve or any plumbing from the
    secondary air pump?

    Thanks again

    Simon
