CV4 High-Pressure Radiator Cap CV-30capKTM - The CV4's radiator cap increases the boiling point of the water in your bike's radiator by increasing the amount of pressure. A motorcycle's radiator cap is similar to the safety valve on a chef's pressure cooker. Since the boiling point of water increases when the water is placed under pressure, this radiator cap has a coil spring between two rubber seals. As the water heats up, it expands and puts pressure on the radiator caps' spring. When the radiator's internal pressure exceeds the spring rate of the cap, the hot coolant escapes and overflows between the two rubber seals.
