Porsche 996, 997, 986, & 987 Water Pump Failure

These water pumps have plastic impellers and overtime the impeller gets worn and breaks. When the impellers break it causes engine overheating and the broken pieces from the impellers cause a blockage in coolant passages. This causes the internal temperatures to rise resulting in internal engine damage or failure. We recommend replacing the water pump in your 996, 997, 986, or 987 every 3-4 years.
