Hello,
I have a coolant leak on my 1.9TD XUD it is coming from where the rubber hose after the metal section joins just behind water pump. There are three pipes two small and one large

What is this part as I think it is leaking? I have checked but can not find any parts.

Please help!

This the bugger? Could be the oring.

Thanks exactly what I was looking for!

This is where my car is leaking from. Very awkward to get to with it being above the driveshaft and subframe. Now that I've seen this I will get at it tomorrow so thanks for the post
