My 2000 Accord (60k miles) is occasionally losing coolant externally;
i.e. once in a while there is a small puddle (2 inches in diameter) on
the driveway; I can't seem to see where it's coming from. All hoses
appear to be in good shape; temp gauge remains the same as always
(just under half-way). When it is parked after driving, there is the
distinct odor of coolant, but can't find the source. Perhaps a pin-
hole leak in the rad or a hose? What about the rad cap - after 8
years, should it be changed?

Dealer ran a pressure test at last service in June and said all was
normal. Any ideas?

Thanks!
