Gates Radiator Cap to suit Mazda CX-3 and Mazda CX-5 and Mazda3 models built from 2017 to 2019, supplied ready to fit with no modification required. Replace the cap, thermostat and hoses together on high-kilometre vehicles - they are cheap compared with a head gasket. Hose is moulded to the factory shape with the correct bends, clip locations and internal diameter. Pressure rating is 110kPa; running the wrong rating will either boil the coolant or stress the radiator seams. Opening temperature is 85 degrees Celsius, matching the engine management calibration. Sold new with Lifetime warranty cover and full technical support.
