Here is a weird one...
On a couple of occasions I have discovered rad coolant on my garage floor. The thing is this has happened once two years ago, and now twice in the last month, both times it has been after a maintenance, and both after a short trip (5mins) preceded by a longer trip (2-4 hours) the day prior to the leak. Otherwise I have no other indication of a leak.
Anyone have any insight to this?
Thanks.

How much coolant? Where under the car (right, left, very front, around the front floor boards)? Is the heater working properly and is the temperature gauge showing the temperature it normally does?

It could indicate a serious developing problem, or mean something as simple as a hose clamp that needs tightening or the coolant recovery bottle was overfilled and the excess coolant is being blown out the overflow tube. Could someone look under the hood and get a clue where it's coming from?

DSHornet, thanks for the reply.
The leak appears in the middle at the front. We cannot visually detect anything that appears to be leaking. The leak usually is only a few drops to several drops, creating a damp spot, not a puddle, and has not appeared since the weekend. There is also no noticible change in my temp gauge. I must schedule another maintenance for next week anyway.

Sounds to me as though the mechanics have spilt some onto the floor pan or bodywork when filling/topping it up and as the residue has to get out from under there it drips down to the place you see it. Once it has dissepated there isn't any more so no more wet spots. (bit like grandpa leaking into his shorts, it's only the last few drips (IMG:style_emoticons/default/smile.gif) )
I would ask the mechanics to be more careful next time as antifreeze can lift off paintwork and they don't need to be so sloppy.

We had the same problem and it turned out to be that plastic radiator drain plug had split.

Well, after two tries, they found my problem: Coroded (sp?) hose clamp!
Funny how that was missed the last two years, as this should have been inspected several times according to the maintenance schedule.
