Sweet Smell after driving 98 jetta vr6

After a 10-20 mile trip, my jetta has a sweet smell around the engine. None of the coolent is leaking or anything, so I don't know what it is. There is no white smoke either.I just want to know if this is something to worry about or not. Thanks

sweet smell is normally coolant. check next to the coil pack at the coolant flange for leaks. it normally leaks here
