Common issues & symptoms

Overheating & Rapid Deterioration: If the pump fully fails, coolant circulation stops, leading to overheating—which can cause serious engine damage.

Strange Noises: Squealing, creaking, or grinding noises can indicate bearing failure or internal damage within the pump.

Coolant Leaks: A failing or worn water pump may begin leaking coolant, often noticeable as puddles beneath the rear of the vehicle or in the engine bay.

Accessory Belt Problems: A failed pump can throw off the serpentine drive belt, potentially causing accessory drive issues.

Maintenance Insights Proactive Replacement: Given the catastrophic failure risk and potentially swift progression from minor to major leaks, many enthusiasts and mechanics recommend replacing the water pump pre-emptively at the 60,000-mile interval.
