Adrad Radiator Cooling Fan Assembly to suit Mazda3 2.0L Petrol models built from 2018 to 2020, supplied ready to fit with no modification required. Pressure rating is 80kPa; running the wrong rating will either boil the coolant or stress the radiator seams. The Copper construction resists coolant additives, heat cycling and pressure fatigue. Opening temperature is 90 degrees Celsius, matching the engine management calibration. Hose is moulded to the factory shape with the correct bends, clip locations and internal diameter. Replace the cap, thermostat and hoses together on high-kilometre vehicles - they are cheap compared with a head gasket. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. Supplied new and backed by a 12 Months warranty.
