That was my symptom as well. I originally had a load of water leaks due to
ageing (car had reached 18 years and 160k miles). The water pump wasn't
that old, so I discounted it originally and concentrated on the bad leaks -
 radiator, plastic flange at rear of block, expansion tank. After replacing
all of these, one leak remained with water appearing at the bottom front of
the block - this turned out to be the pump.
