Polo radiator/coupling leak

[Flutter]

Hey Guys, recently I found this leak in on the bottom left (passenger) side of my radiator (Car is an 05 GTI).




I tried searching but didn't find anything so I thought I would ask, my questions about this are.

First, is this leak coming from the radiator side or from the elbow join?

Second, what is involved in getting it fixed? Is it as simple as putting in a new seal/gasket/o-ring or is more than that involved?

Third, does anyone know the part number for that elbow join? I haven't been able to find it.

Thanks in advance guys.

It's the radiator that's stuffed.

The end tank has separated from the core.

If in doubt, get it pressure tested.

Polo GTI s are notorious for leaking rads,new one from dealer are pretty well priced.
