Coolant leaking from the passenger side of the engine could be coming from this heater pipe.  Its common for this to leak from the mounting tab on the alternator bracket.  It will leak from the weld and down onto the intercooler pipe.  It may leak to the ground, but typically the leak is small enough it just drips on the pipe and evaporates from the heat in the intercooler pipe.  A common sign of this leaking is an orange stain on the intercooler pipe.  This is residual from the coolant evaporating off and leaving a residue.
