Coolant Leak
frankoprifti:
I've been losing coolant like in a month I'm going from max line to min line. Tonight just found a place that has coolant around. It's a place just under the battery. My Golf is a Golf mk5 1.4 16v. Can you guys give me an idea what is this part that is leaking the coolant? If you check the images attached you can see that there is some water and some pink residue.

Hard to tell really, you could get an inspection mirror and see if you can find any hoses that have residue on them. But here's my setup which makes it easier to see because they're blue silicone for the coolant hoses, giving you an idea which ones to check and inspect for residue leaks.

I think it might be the coolant flange that found out is known to fail and its around the same area. But will visit a mechanic today or tomorrow to find out what it really is. Thank you for your picture

Found out by hand it was leaking at a place that looked like a thermostat housing

I dont know what this is called but this is which is broken on mine. Its leaking from the bottom
