This coolant regulator is specially designed for high-temperature use on race tracks. It opens as soon as the engine temperature reaches 70 °C. This thermostat helps to keep the engine temperature in the optimum range – especially on the racetrack, where the engine temperature can rise quickly. It helps to reduce the transmission and engine oil temperature, which is beneficial for long-distance driving. This thermostat can help to maximize the performance and service life of the engine.
