Item Description Parts Maker NISMO Parts Name Racing Radiator Cap Parts Number 21430-RS013 Vehicle NISSAN SUNNY Model B12/B13/B14/B15 Year Since 1985/9 Outer Diameter 45φ Operating Valve Pressure 1.3kg/cm2 seal Heat-Resistant Silicone Rubber Caution Item NISMO Racing Radiator Cap keeps the pressure inside the cooling system high, so please be sure to check the radiator and halls for damage or leakage before installation. Please note that due to aged deterioration, leakage may occur due to high pressure even in places where there was no problem with low pressure until now. Suitable for models fitted with radiator caps of small type (outer diameter 45φ). Enhance cooling capacity by keeping the pressure within the cooling system higher than that of standard radiator cap, which makes coolant less prone to boil and evaporate. The boiling point becomes higher up to 6 deg compared to the standard cap whose relief pressure is 0.9kg/cm2. Dispatch / Payment / Other notes Dispatch All items will be shipped by japan post.
