As for the other tank, I gave up trying to clean that and replaced it with a new one from GSF. Was under £20 I think.

Here is one after the gravel treatment:

And now I know why my coolant has gone black and thick. There must have been some residual coolant in the pipes before filling up.
Looks like I've got a fun couple of weeks before bustypes.

-I had thought it might be oil contamination changed oil cooler, but it's all black with no cream forming.

Thanks for all of the replies. I topped up the expansion tank behind the number plate with water and so far it''s not dropped in level so no leaks.
I''ll follow all of your advice and do a complete coolant change, once i''ve worked out how to do that

My van (1989 1.6 diesel) does not have an expansion/top up tank. Is this a problem?

Yes

Can you advise on refitting the extra tank. I can see that the parts are available. How does the top up tank connect to the rest of the system?

Mine is not a diesel but there are loads of images to compare yours with, also maybe worth posting an image of your engine bay, as there must be a gap where the missing bottle should be and would give guidance to others to comment on.

on a standard diesel t25 the top up tank is behind the numberplate flap and has a single rubber pie from the header tank or the header tank cap ( depending on age) to the top up tank.
