The OE Match Water Pump is a high-quality replacement cooling system component designed to maintain the continuous circulation of coolant throughout the engine and radiator system. Manufactured to OE specifications for fit, function and durability, this water pump ensures efficient heat transfer and stable engine operating temperatures under all driving conditions.
Fits:
- Porsche 944 2.7L 8V 1988-89
- Porsche 944S2 3.0L 16V 1989-91
- Porsche 968 3.0L 1992-94

- Porsche 968 CS 3.0L 1993-95
- Porsche 968 Turbo S 3.0L 1993-94
As one of the most important components within the engine cooling system, the water pump drives coolant through the engine block, cylinder head, radiator and heater circuit, helping to prevent overheating and maintain optimum engine performance. This OE Match replacement is ideal for routine maintenance, cooling system repairs and engine restoration projects.
What This Product Does:
- Circulates coolant throughout the engine cooling system.
- Transfers heat away from the engine and into the radiator.
- Helps maintain correct engine operating temperatures.
- Supports efficient heater system performance.
- Prevents coolant stagnation and localised hot spots.
- Protects critical engine components from excessive heat.
Symptoms Of Wear Or Failure:
- Coolant leaks from the pump housing or shaft seal.
- Rising engine temperatures or overheating.
- Coolant loss without visible hose or radiator leaks.
- Grinding, whining or rumbling noises from the water pump bearing.
- Coolant residue or staining around the pump assembly.
- Excessive play in the water pump pulley.
- Reduced heater performance due to poor coolant circulation.
- Steam or coolant odours from the engine bay.
Why Replacement Matters:
- The water pump operates continuously whenever the engine is running and is exposed to constant rotation, pressure changes, coolant flow and temperature fluctuations. Over time, bearings, seals and impeller components can wear, reducing the pump's ability to circulate coolant effectively.
- A failing water pump can result in coolant leaks, poor cooling system performance and engine overheating. If left unresolved, overheating can cause serious engine damage, including warped cylinder heads, failed head gaskets and accelerated wear of internal components. Because the cooling system relies on consistent coolant circulation, a healthy water pump is essential for long-term engine reliability.
- Replacing a worn water pump restores efficient coolant flow, maintains proper engine temperatures and helps protect against costly overheating-related repairs. An OE Match replacement provides factory-style fitment, dependable performance and long-lasting durability, ensuring your Porsche cooling system operates as intended.
