Coolant from turbo

[Ford s]

Hi,
wondering if anyone can help iv been having problems with my coolant system lately.

when coming back from a drive ill turn my car off and my coolant seems to be draining back into my overflow tank from the turbo and its bubbling up is this normal or any cause that may do this?

Coolant continues to circulate through the turbo for a bit after you shut the car off. That's a good thing, and totally normal. It gets really hot.
Unless you're losing coolant, it's working as it should.
