I've always driven junkers/older vehicles and have developed a keen sense for leaks/smells, etc. It has served me well.
I have noticed that many newer vehicles, even going back 10 years or so, will produce a distinct coolant smell on startup. I notice it in parking lots on stranger's vehicles, but also with vehicles belonging to family members . . . that I know are not leaking internally enough to been seen by a decreasing coolant level.
It seems like it's a burning coolant smell, but could it just be the system venting? . . . but I wouldn't think it could vent through the overflow on a pulse of pressure at start-up.
Is there any explanation dealing with the pressurized expansion tanks or new coolant system design? Is there an emissions system smell that is similar to glycol?
It has been one of those things that has consistently baffled me . . . "This many new cars can't be burning coolant."
