D2 TD5 front coolant drain plug-washer?

Hi can anyone tell me what size this should be, what type and the torque to do it up to, please?
Mine came without one and I was in a hurry so put it back the way it was.
So obvs it is now weeping!
I have no access to RAVE at the moment and Haynes doesn't seem to give the torque setting.
All contributions will be gratefully received.
Thanks in advance.

I believe you'll need a 13mm socket for that plug which should make it an M8 bolt. That would be 8mm nominal diameter so I would buy a few copper washers of different sizes around that mark. As for the torque, I don't think I ever came across a setting for the coolant drain plug so I just use good judgement, knowing that the washer is actually doing the sealing.

Good luck.

I dont know the dimensions but it's a dowty washer p/n PYF100860 and the torque for the drain plug is not specified in RAVE

Cheers all.
Have now got one from a local landy place, they only had one on the shelf and yes even they didn't know what torque. So I'll use sensible judgement!
Thanks again!
