Engine overheating: Frequent overheating o r temperature gauge rising above normal during drives.

Low coolant level warning: The dashboard may show warnings about low coolant.

Steam o r coolant smell: Steam from the engine bay o r a sweet coolant odor indicates leaking.

Visible damage: Cracks, corrosion, o r wet spots on the radiator o r hoses.

Reduced heater performance: Sometimes coolant leaks reduce heating efficiency inside the cabin.
