Roland,

I think coolant may be leaking from the "weep hole" at the bottom of your
water pump.  As the water pump bearing becomes worn, it usually begins to
leak out of this small how at the bottom.  If so, then it is time for a new
water pump.  They are a bit hard to get to, but overall a fairly easy job.
I had to replace one in a parking lot once.

Hope this helps.
