Even when coolant begins to heat up, pressure begins to build inside the radiator. BLOX Racing’s high pressure radiator caps ensure that this pressure is properly relieved so excess heat is spent and fluids flow into the overflow tank.
Standard caps are designed to open at 1.1 bar, but BLOX Racing’s 1.3 bar caps are able to withstand the increases in heat and pressure and prevent the radiator from overheating.
BLOX Racing radiator caps are rated 1.3 bar and greatly increase your radiator’s cooling efficiency and performance.
* Some aftermarket radiators do not use a factory cap. For example, Koyo uses Type A on most their radiators regardless of application. Please check yours before ordering.
