That'll be your coolant, and there could be a number of things causing it... a blown head gasket will do it... a coolant leak where the coolant leaks onto a hot engine block will do it... a faulty radiator cap which opens too easily can cause this.... excess coolant causing the system to overpressurize and have to relive frequently will, as well.
