What is a common symptom of a failing water pump?

A common symptom of a failing water pump is engine overheating because the water pump is a critical component of the engine's cooling system. It circulates coolant throughout the engine and radiator, helping to dissipate heat. When the water pump malfunctions, it can no longer effectively circulate the coolant, leading to a buildup of heat within the engine. This excessive heat can result in engine components being damaged and can lead to catastrophic engine failure if not addressed promptly.

Understanding this symptom is vital for recognizing when cooling system issues might be due to the water pump rather than other components, such as the thermostat or radiator.
