Seat Ibiza 6L - Coolant leak (leak identified) - TheSeatGuy

Hi!

I have a Seat Ibiza 1.4 (6L). Just noticed the other day that there was a coolant leak. Got under the car and noticed that it was leaking from a part that connects to the bottom of the radiator. Between the lower radiator hose and the radiator. Don't know the exact name of the part but have attached a picture that shows where the leak is. Have made a red circle of where it leaks.

Now to the question. Do I have to change the whole radiator or only the black piece?

Thanks in advance!

My son has the same car, same engine and had the same problem.

You either need to replace the whole radiator or, assuming it's a slight leak, do as we did and put some Radweld in. Some on here wouldn't touch the stuff because basically it's a bodge, but I consider it a useful aid to bangernomics.

If you've taken it off and found a leaking crack, I would try coating it inside and out with a loose paste made from fibreglass resin and filler powder.

I might try it, but I wouldn't put much money on it withstanding regular cycling in hot slightly corrosive solution. Even the bottom of a radiator can get quite warm.
