Coolant Thermostat Housing For Toyota Duet, Daihatsu Sirion 1632197207
Replace failing factory components with this brand-new aluminum coolant thermostat housing, engineered as a direct match for interchange numbers 16321-97207, 1632197207, and 16321 97207. Built specifically for the Toyota Duet (M100A/M101A/M110A/M111A, 1998–2000) and Daihatsu Sirion equipped with the 1.0L EJ-DE gasoline engine, this compact assembly restores precise thermal management to aging cooling systems.
Machined from lightweight aluminum for superior heat dissipation, the housing features a hermetically sealed design that halts slow coolant seepage and prevents engine overheating. Its calibrated internal passages deliver steady fluid circulation, resolving erratic temperature gauges, dashboard warning lights, and reduced fuel efficiency caused by restricted coolant flow.
Benefits & Practical Tips
- Always cross-check your original part number against 16321-97207 before ordering to confirm exact compatibility.
