Installation Notes and Tips

Verify the vehicle’s year, model, and HVAC configuration before installation. Confirm the core dimensions and tube orientation against the original unit to ensure proper alignment with the factory heater case and coolant lines. Because this is an OEM-specific heater core, fitment should be matched to the listed Mazda applications rather than universal HVAC use.
