look at the very bottom of the water pump housing where the shaft comes out for the fan. There is a weep hole. Often it leaks there ans so little it evaporates before ever getting to the ground. If it looks damp around the weep hole you found your problem.

first of all, get a good scanner to determine the real temps your engine is running at. That dash gauge is notoriously wrong. Mine reads 210 when in actually it is 185 or so
