Once you have removed the standard oil cooler from the 16v block, like so:

how do you remove the threaded insert that it sits on from the block? I need to remove it to swap onto my other block, but there are no bolts or anything holding it in, and I don't want to break the threads by using grips.
This is the bit I mean:

Or can you buy a replacement part from Citroen? If it is only a couple of quid I'd rather just do that rather than messing with mine?
Thanks in advance
