Coolant smell - Do you smell it just occasionally or all the time? How full is the coolant level? If it too high it can seep out of the top of the expansion tank cap when the engine is hot. That has happened to me.
If it is not the coolant level, I suggest doing a thorough search. Take a good look at all the hoses. Also check the passenger side of the radiator for leaks. Pay particular attention to the "seams". The expansion tank cap might also be tired. The expansion tank could have developed small cracks in the bottom. Finally, if you still can't find it remove the timing belt cover and look at the water pump.
