So I’ve had an intense coolant smell coming out of under my engine bay the past week and it got to the point where I actually thought I had a coolant seal go. Spent some time like staring at it for like two hours, then ran it to another spot, killed the motor straight to the hood and stared at it more and thankfully it paid off even though I probably looked crazy, but there was literally no sign of any leak only stank. Long story short it a coolant line supposed to run directly butted against the back of the alternator?

also yes I have the diagrams just looking for a double check.

 

Nothing shouldbe rubbing, obviously. The throttle body coolant lines are there, but there shouldn't be metal to rubber contact anywhere. If someone messed with it, such as to bypass the throttle, then you probably want to undo that or sheath the line in something. But really sheathing isn't a permanent solution.
