Mazda Thermostat Housing

Choose a Mazda thermostat housing by application

Find a Mazda thermostat housing by matching the model series, build date and engine to the selected product. Check the original part reference and compare the housing layout before ordering. The Mazda badge alone does not identify the correct cooling-system assembly.

Browse the model category

The Mazda BT-50 thermostat housing category provides a route to the listed diesel applications. Use the vehicle and engine details on the product page to confirm suitability. A model example does not establish fitment across every engine or generation.

Check the connections and included components

Compare the number and direction of the hose outlets, mounting face, bolt positions and sensor connection. Confirm whether the chosen assembly includes a sensor, thermostat and seals, or requires any of these separately. The listed BT-50 product specifies a sensor, but package contents should always be checked for the exact item being ordered.

Need help matching the housing?

Contact Parts Factory Australia with the vehicle series, build date, engine details and photos of the housing and connector if the reference or shape differs. Have a coolant leak or temperature fault assessed before choosing the replacement component.
