Today I was driving and got the low coolant warning. Immediately after I got to a red light and saw some smoke under my hood. 2 mins later I got to my destination and more smoke. Not crazy hotbox amount but definitely there. The ol coolant hose snapped, on both ends. Didn’t even know about a bleed system until I had already driven it 20 miles. I just swapped the part and topped the coolant. Noticed way less smoke still after, assumed it was the hot splashed coolant touching the hot parts. No new leaks noticed. Sprayed the engine bay down when I got home. So should I still do the bleed procedure tomorow morning? The coolant tank was a bit less than when I filled it, and there isn’t really a clear fill line?? I see one small mark but it has no words. I did use the hot air to defrost my windows. Could the driving have got the air out? Did I possibly damage the engine? The temp gauge never went over halfways.

Doesn't matter, if you didn't overheat, and you still have heat in the cabin there isn't that much air in the system. Yes it should be bled, but you're fine.
