My '97 had a faint coolant smell when I shut it down in the garage. It was very minor seepage from the water pump cover gasket. It never amounted to anything so I never fixed it. Coolant never even showed low, it was that minor.

I have the same thing on my '01. It's coming from the water pump area, but I'm not sure if it's the pump itself or the housing gasket. Either way I don't lose enough coolant to worry about it. I've been driving the car for a year now and I haven't had to top it off. You can smell it though. The other possibility is the overflow hose. It's on the other side (back left of the engine as you face it). Sometimes they crack and leak.

Until it's a big leak, I wouldn't worry about it.
