Increased valve opening pressure provides stable cooling effect.

By increasing the opening pressure of the pressure regulating valve to 127kpa (1.3kg/cm²), the boiling point of the coolant is raised. This keeps the pressure in the cooling system high, suppressing boiling and evaporation of the coolant. This provides stable cooling even during sporty driving. The seal uses a highly heat-resistant and durable silicone gasket. This maintains a tight seal over the long term, preventing coolant leaks and pressure drops. Compatible with a wide range of Mazda's major models.
