Designed originally for racing engines, today’s compact production engines can also benefit from the used of GReddy’s Radiator Bleed Tank.  The air in the radiator causes over heating. The GReddy Breather Tank removes the air in cooling system. By the fuid swirl in the tank, Breather Tanks separate coolant from the air and will contribute to the radiator’s efficentcy. Block-off radiator cap included.

GReddy high-pressure radiator caps are OEM style caps that directly replace the factory cap. GReddy Radiator Caps have a main valve pressure rating of 127kpa 1.3kg/cm2 which allows for a higher boiling point. A higher boiling point ensures protection against over heating and also ensures your car maximum coolant flow at higher temperatures. Two types are available to fit most Japanese vehicles.
