615RA003 | Genuine International® Radiator

Functions: 
Engine protection: By maintaining optimal engine temperature, the radiator prevents overheating, which can cause severe engine damage.
Heat dissipation: The radiator's primary function is to cool down the engine coolant by transferring heat from the coolant to the air passing through its core.
Coolant circulation: The radiator is part of the engine's cooling system, where coolant circulates through the engine block, absorbing heat, and then flows through the radiator to be cooled.

The radiator is important for protecting the engine by maintaining its optimal temperature and preventing overheating, which can lead to serious damage. It cools the coolant by transferring heat to the environment, and circulates the coolant through the engine to effectively dissipate heat.
