MotoRad® Engine Coolant Safety Lever Radiator Cap (7D1555). 13 psi is the pressure. MotoRad radiator caps are engineered and built to provide precise control over the automotive cooling system. MotoRad safety lever radiator caps have a lever that secures the cap to the filler neck and must be lifted before removal. When the lever is lifted, the valve pressurizing the cooling system is opened, and pressure is vented through the overflow tube, allowing the radiator cap to be removed safely.
MotoRad radiator pressure caps are engineered to provide precise pressure control for the automotive cooling system. The majority of standard radiator caps are also available with a safety lever. MotoRad radiator caps are made to meet all OEM specifications, and each part is factory tested before being shipped to customers.
A slowly deteriorating, worn out, or faulty radiator cap can cause overheating, coolant loss, and even major engine damage.
One of the radiator cap's functions is to keep the cooling system under pressure. When 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 can overheat.
If you replace a thermostat and the radiator cap is more than three years old, it is likely that it will not hold the same pressure as a new cap. Explain to your customer that by replacing the thermostat and radiator cap, their vehicle will be able to run at the specified operating temperature and the coolant system will be properly pressurized.
The radiator pressure cap is a critical part of the system. The cap monitors the system pressure and adjusts to keep it at the desired level (normally in the 15 psi range). The correct system pressure will not be maintained if an incorrect or defective cap is used. If the system pressure is too low, the coolant will boil at unsafe temperatures. Damage to the system can occur if the system pressure is too high, potentially resulting in coolant loss and an engine overheating condition.
