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
