Vacuum leak?

[Carlos B]

So I was driving home from work the other night when suddenly my engine started overheating. I pulled aside and opened the hood when a hissing noise appeared, I managed to get home safely and make a quick video:

Why are you calling this a vacuum leak?
Search, common issue. Need to replace the plastic parts of your cooling system. The one that was hissing is the degas bottle, but all of them need to be replaced now.
