MotoRad® engine coolant radiator cap (604B82). 16 psi is the pressure. MotoRad radiator caps are designed and manufactured to provide precise control over the automotive cooling system. This high-quality product is expertly made in accordance with stringent industry standards to provide a well-balanced design and a high level of craftsmanship. It is built with industry-leading materials and cutting-edge technology to ensure long-term dependability and value. This product is distinguished by unrivaled quality assurance. MotoRad radiator pressure caps are designed and manufactured to provide precise pressure control for the automotive cooling system. Most standard radiator caps are also available with a safety lever. MotoRad radiator caps are manufactured to meet all OEM specifications, and each part is factory tested before shipping to customers. MotoRad standard radiator caps are an excellent replacement for worn or faulty radiator caps that occur over time. Radiator caps are simple to install and remove because the shell of the cap is interdependent of the sealing gasket, stem, and bottom plate. A slowly failing, worn out, or faulty radiator cap can cause overheating, coolant loss, or even major engine damage. One function of the radiator cap is to keep the cooling system under pressure. If the pressure in the system drops due to a faulty radiator cap, the boiling point of the coolant falls as well. If the boiling point falls low enough, the engine may overheat. If you replace a thermostat and the radiator cap is more than three years old, it is likely that it is not holding the same pressure as a new cap. Explain to your customer that by replacing the thermostat and radiator cap, their vehicle will run at the specified operating temperature and the coolant system will be properly pressurized. The radiator pressure cap is a critical component of the system. The cap monitors the pressure in the system and adjusts to maintain the desired pressure (normally in the 15 psi range). The correct system pressure will not be maintained if an incorrect or faulty cap is used. If the system pressure is too low, the coolant will be allowed to boil at unsafe temperatures. If the system pressure is too high, it can cause damage to the system, potentially resulting in coolant loss and an engine overheating condition.
