The Cusco High Pressure Radiator Cap raises the boiling point for better cooling efficiency, and prevents over heating. The fortified main pressure valve spring and silicon packing are used to raise the pressure inside the radiator for a higher boiling point.
The coolant will not boil easily, prevents air bubbles in the block and radiator core with improved heat transfer. Cuscos high-pressure radiator cap works at 1.3kg/cm2 at zero atmospheric pressure. In theory, the atmospheric pressure of the road surface (approximately 1.0kg/cm2) is added and the pressure is 2.3kg/cm2.
