C5 phase 2 sump plug size

[micky707]

Hi guys,

Can some kind soul tell me the size of the sump plug to remove it, is it a box wrench or a torx fitting as it is looking rounded, it is a phase 2 56 plate .


Thanks,

Micky

Mines a hex recess (Allen key) fitting, but I believe that some have a square recess.
They are very soft, and round off easily - I had to replace mine when I bought the car, but a chisel got a purchase on it with little trouble.

Cheers, it is an allen key recess but not sure what size it is.

Tried a chisel, but as you say its very soft and to no avail, any other ides welcome before i have to go to the guys at the workshop

The Mk 2 C5 which I've just parted with used an 8mm hex socket

John's right, just checked mine and it's an 8mm hex.

If your's has started to round then you might need to insert a flat blade screwdriver on one of the faces to make it a tight fit.

Also, I would use an 8mm hex bit from a large socket set, not just a normal allen key, that way you have more precise control.

Once it's out, if it is damaged then get a replacement from Citroen (can't imagine it's that expensive)
