Its leaking very slightly at the pipe union with the "hairbrush" cooling section (rack to cooler pipe). My only reasonable choice is to replace the whole assembly with a good used one .
What tool do i need to remove the hose from the rack pipe - its one of those quick fit affairs I think or is there a reliable alternative method. The rest is just hose clips which should be OK.

The link to the schematic is here for reference :

Its where part #7 joins to part #13

many thanks

 

I have attached some excerpts from the X308 tech manual. The fitting requires a special tool. I think from looking at it you can probably get it at the local auto store. The lowest illustration is for the same connector used on the fuel system. I know the parts stores have plastic tool sets for fuel system work.
I hope this helps.

 

Many thanks
