Water pump. Porsche 958 Cayenne / Macan 95B / 970 Panamera DIESEL

Water pump with gasket. The engine water pump plays a vital role in regulating your vehicle’s temperature by keeping coolant circulating throughout the engine. Over time, the pump’s internal bearings and seals can wear out, leading to noise, coolant leakage, and reduced cooling efficiency. One of the most common signs of a failing water pump is coolant dripping from the pump’s “weep hole,” indicating internal seal failure.

Signs of a Failing Engine Water Pump

• Coolant Leaking From the Weep Hole

Fluid coming from the weep hole is a strong indication that the pump’s internal seals have deteriorated.

• Excessive Play in the Pump Pulley

Movement or wobbling at the pulley shaft suggests a worn bearing, which can lead to pump failure.

• Squeaking or Chirping Noise at Idle

A failing bearing often produces high-pitched noises when the engine is idling.

• Engine Overheating

If the pump can’t circulate coolant properly, the engine may begin to overheat.

• Low Coolant Warning Light

A cooling system leak—often caused by a worn water pump—may trigger a low coolant alert on the instrument cluster.
