Compatible models: EJ engine only Valve opening temperature is set to 71℃, 7℃ lower than the original. By circulating the coolant from the radiator faster, it prevents the water temperature from rising and maintains the appropriate water temperature range for the EJ engine. Specifications: Valve opening temperature 71℃

Designed specifically for Subaru vehicles. The water temperature range where it is easiest to bring out the engine's power is 70 to 80 degrees Celsius. In order to effectively suppress not only overheating but also overcooling, the cool thermostat sets the valve opening temperature to 71℃, which is 7℃ lower than the stock temperature. By circulating coolant cooled by the radiator more quickly, it prevents the water temperature from rising and maintains the optimum water temperature range for the EJ engine. It not only reduces engine stress and brings out Subaru's original performance, but also protects the engine. *When replacing, we recommend using Cool LLC.
