I have water leaking from what looks like a blanking plug on a pipe at the top left corner (as you look from front).

 

A very fine jet of coolant squirts from it,this blanking plug looks like a rubber thimble with a jubillee clip holding it onto a stubby short pipe (16mm dia) that comes from the radiator,you can sqeeze it,its soft i have found pic of what it looks like.

 

Anyone know a part number for it i have looked on 7zap but cant see it.

 

Its the one in the top right of this pic.

Mick - am I looking for MK4 2.5 5 pot or Mk5 Diesel?

 

Forget it, I realise now it's in the Mk5 Diesel section, doh

 

 

Add/edit - bloody nightmare - think we might need an actual picture

So i guess that summat like this will do the job

 

https://www.ebay.co....5.c100005.m1851

 

Why have an outlet in a radiator that requires blanking, unless the same rad is used on another vehicle and the outlet is used,i dunno.

 

Looked on Alan Howatt radiator removal video,and his rad does not have that outlet,it looks like the hole is sealed up in a manufacturing after thought adjustment.

 

Look at 1.03 in this video.

I have to conclude at this point that the blank in question is part of the radiator assy as it is not shown as a separate part, if we were in normal times I would happily order a radiator and see what turns up..

That "blank" in the e bay advert looks a possibility but of course it depends on the internal diameter.
Mick, if you are desperate, is it worth a punt
