Product information
By increasing the valve opening pressure, a stable cooling effect is achieved.
By increasing the opening pressure of the pressure regulating valve to 127 kPa (1.3 kg/cm²), the boiling point of the coolant is raised. This maintains a high pressure within the cooling system, suppressing boiling and vaporization of the coolant. This ensures stable cooling performance during sporty driving. The seal uses a silicone gasket that boasts high heat resistance and durability. It maintains airtightness over a long period, preventing coolant leaks and pressure drops. It is compatible with a wide range of major Mazda models. >>Learn more
