Oil sump nut size
As subject says... what spanner size do I need to use for the oil sump bolt? I am pretty sure my biggest 18 one didn't fit and had to fiddle about with the adjustable one...

I'm sure it's under 20, that'll be 19 I guess.

21mm or 13/16th in old money. Same as old type spark plugs.

Re: Oil sump nut size
Could've sworn mine was a 10mm allen key - (or do 21mm sockets fit 'em too)?

2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)

Re: Oil sump nut size
I've got a square key thing with two ends, one goes 'in' the sump nut and the other end slots into a suitable socket. Most car shops sell them and refer to them as Peugeot/Citroen sump nut keys I think.

Re: Oil sump nut size
Hm, interesting - on my 2.1TD it was just a normal nut. I guess it's changed on an HDi...
Can I just use a 10mm allen key then instead of spending monies on a new ratchet set/spanner?

Re: Oil sump nut size
On my 2.0HDi the spanner size is 21mm, as it is on my Expert van Hdi, as it was on the fleet of 30 plus HDi vans that I used to service.
It is 21mm on my brother's 1.9td as well.It is even 21mm on the Ford Fiesta sump plugs (Peugeot Diesel engines).
Some of them have a 9mm square hole in the middle of the nut as well as being 21mm, as reported, there is a special square tool to fit this.
Both my vehicles have this square hole.
