This OE-Match pump is ideal for replacing aged, leaking or failed original pumps, or as part of a comprehensive cooling system overhaul on the 718 Boxster/Cayman.

The water pump circulates coolant from the radiator through the engine block and head, ensuring heat generated by combustion is efficiently transferred away and dissipated. By maintaining a constant flow and consistent coolant circulation, it helps regulate engine temperature, prevents overheating, and supports reliable engine performance under all driving conditions.

Over time the water pump’s internal impeller, seals and bearings can wear or corrode. When this happens, coolant flow becomes restricted or leaks may develop - reducing cooling system efficiency and increasing the risk of engine overheating. Replacing a worn or failing pump ensures your Porsche’s cooling system remains fully functional, protects the engine from thermal stress, and maintains long-term reliability.

When to Replace:
• Coolant leaks visible around the pump housing or gasket area
• Engine overheating, particularly under load or in warm weather
• Coolant loss without obvious external hose leaks
• Noisy operation from the pump (bearing noise, grinding)
• During major cooling-system maintenance — e.g., when replacing radiator, thermostat or coolant hoses
