TRD's High Pressure Radiator Cap raises the boiling point of your coolant for increased cooling efficiency and prevention of over heating with the TRD High Pressure Radiator Cap. When coolant boils, small air pockets are created. As the coolant passes through the block and radiator core, the air pockets reduce the cooling efficiency and will eventually cause the engine to overheat.
TRD's High Pressure Radiator Cap operates 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.
Genuine part. Made in Japan.
