The radiator’s main role is to remove heat from the engine coolant that carries thermal energy away from the engine block and cylinder head. Hot coolant flows into the radiator, where it travels through a series of fine tubes and cooling fins. Air passing through the radiator core (from vehicle motion and fans) absorbs the heat, lowering coolant temperature before it returns to the engine.

Proper heat rejection helps:
• Maintain optimal engine operating temperature
• Prevent overheating under everyday and high-load conditions
• Support fuel efficiency and emission control
• Preserve engine component durability and longevity
