Which of the following components is NOT part of the radiator support?

The radiator support serves as a structural component that holds and aligns various parts of the cooling system, including the radiator itself. However, the radiator is indeed not considered a part of the radiator support. The radiator is a separate component that is mounted onto the radiator support to facilitate cooling of the engine coolant.

The side baffles, upper tie bar, and lower tie bar are all integral parts of the radiator support structure. The side baffles aid in directing airflow through the radiator, while the upper and lower tie bars help maintain the structural integrity and alignment of the radiator and other adjacent components. Understanding the individual components’ roles can highlight how they work together as part of the overall cooling system but also clarify their specific designations within that system.
