Overheating Risk: Yes, a radiator leak leads to a loss of coolant, which is essential for maintaining the engine’s operating temperature. Without enough coolant, the engine can quickly overheat, potentially leading to severe engine damage such as warped heads o r cracked cylinders.

Signs of Overheating: If the temperature gauge rises into the red zone o r you notice steam coming from the engine, it’s likely caused by insufficient coolant due to a radiator leak.
