Beschreibung
Zusammenfassung:	A turbocharger turbine housing can include a base that defines a turbine wheel opening that includes an axis that defines an axial direction; an exhaust inlet flange that defines an exhaust inlet; an exhaust outlet flange that defines an exhaust outlet; a wastegate shaft bore, a wastegate passage, a wastegate opening for the wastegate passage and a wastegate seat disposed about the wastegate opening; bosses where each of the bosses defines a coolant opening; a spiral coolant passage in fluid communication with at least two of the coolant openings where the spiral coolant passage includes at least two windings with respect to an axial dimension of the turbocharger turbine housing; and at least one coolant passage that is in fluid communication with at least two of the at least two windings of the spiral coolant passage.
