Coolant out exhaust?

[Jmayberry2011]

Ok I was driving smelled coolant, low coolant light came on pulled over immediately. Cloud of white smoke out the exhaust. Almost lost all coolant out bottle. Checked oil looked ok. While sitting coolant was draining Out of the pipe behind turbo. Can a egr cooler failure cause me to loose that much coolant out the exhaust that fast? Thank you
