Product Details

Engine Coolant Safety Lever Radiator Cap (ST16) by MotoRad®. Pressure: 16 psi. MotoRad radiator caps are designed and manufactured to offer precise control for the automotive cooling system. MotoRad safety lever radiator caps utilize a lever that locks the cap to the filler neck requiring the lever be lifted before removal. When the lever is lifted, the valve pressurizing in the cooling system is opened and pressure is vented through the overflow tube making it safe to remove the radiator cap.

MotoRad radiator pressure caps are designed and manufactured to offer precise pressure control for the automotive cooling system. Most standard radiator caps are also offered in a version with a safety lever feature. MotoRad’s radiator caps are manufactured to meet all OEM requirements and each part is factory tested prior to shipping to customers. A slowly failing, worn out or faulty radiator cap can result in overheating, loss of coolant or even major engine damage.

One function of the radiator cap is to keep pressure on the cooling system. If the pressure on the system drops because of a failing radiator cap, the boiling point of the coolant also drops. If the boiling point drops enough, it can cause the engine to overheat.

If you replace a thermostat and the radiator cap is more than three years old, chances are is not holding to the same pressure as a new cap. Explain to your customer that by replacing the thermostat and the radiator cap, their vehicle should run within the specified operating temperature and the coolant system will be properly pressurized.

The radiator pressure cap is a very important component of the system. The cap monitors the pressure of the system and adjusts to maintain the desired pressure (normally in the 15 psi range). If an improper cap or a defective cap is used, the correct system pressure will not be maintained. If the system pressure is too low the coolant will be allowed to boil at unacceptable temperatures. If the system pressure is too high, damage to the system can occur, potentially causing loss of coolant and an engine overheating condition.
