Can I choose the bottle by its photograph alone?

Use photographs together with the application details and original reference. A similar-looking reservoir can have different connections or mounting positions.

Open the individual listing for current availability, application details and supplied components. If you are unsure, ask Parts Factory Australia about fitment with your VIN, build date and clear photos of the original part. Review delivery information and warranty terms before ordering.

Mazda Overflow Bottle buying questions

Where should I start for a Mazda coolant tank?

Choose Mazda 3, 323 or BT-50 above, then open the relevant product for its build range and reference. The model categories keep passenger-car and ute applications separate without treating one tank as suitable for the whole make.

Does the bottle include a cap or sensor?

Check the selected product listing for supplied components. Compare the cap arrangement, hose connections and any sensor provision with the original tank; these details can vary between applications.

What shipping and returns apply?

Parts Factory Australia offers free express shipping for items under 500 g and free regular shipping for heavier items. Returns are within 7 days; see our returns information.
