The NISMO Racing Radiator Cap will increase the boiling temperature of your coolant in addition to reducing bubbles and thus will help increase the cooling potential of your radiator. The NISMO Racing Radiator Cap is specially design for all vehicles that need more cooling than the stock radiator cap provides. Nismo is the best for anything Nissan and is the top choice of all major Nissan tuners out there!
FEATURES: NISMO Racing Radiator Cap maintains a higher internal pressure for the cooling system than the standard cap (Valve opening pressure : 0.9kg/cm2 *1.2kg/cm2 for Z32).
It prevents the coolant from boiling and vaporizing easily (the boiling point is approximatery 6?C higher than the standard cap's 0.9kg/cm2 threshold) and improves cooling efficiency. PRODUCT NOTES: - Because the NISMO Racing Radiator Cap keeps pressure in the cooling system at a high level, be sure to inspect the radiator and hoses before installation to ensure that there is no damage or leaks. Older cars are particular prone to problems due to deterioration of parts; even if there was no problem when used with low cooling system pressure, leaks may occur under higher pressure. - Cap can be used on vehicles with a small radiator cap (external diameter Data45). - See more at: http://www.rhdjapan.com/nismo-racing-radiator-cap....
