The DEF Tank Head Mounting Ring (part number 2612453C1) is a component of the Selective Catalytic Reduction (SCR) system in commercial trucks. It is not related to the radiator. The DEF Tank Head Mounting Ring is a circular metal ring that is used to secure the DEF tank head to the DEF tank. The DEF tank is a separate tank that holds Diesel Exhaust Fluid (DEF), which is used to reduce emissions in the SCR system. The DEF Tank Head Mounting Ring is an important component that ensures the DEF tank head is securely attached to the DEF tank, preventing leaks and ensuring proper operation of the SCR system.
