Another place to look for  acoolant leak is the coolant 
"flange"--that pipe running alongside (underneath) the intake 
manifold. The triangular flange bolted to the head at the center of 
this pipe can seep coolant; this seepage tends to collect at the 
lower edge of the block, but it can be slow enough to never leave any 
puddle below the car. On my car, the source of this seepage( i.e., 
visible drips) became obvious only after  allowing the  engine  to 
cool down for a few hours.
