pump, thermostat, drive (serpentine) belt and the required gaskets for both the
pump and thermostat housing.
Fits:
Porsche 992 turbo with PDDC
991.2 For cars with Option Code

Designed as a comprehensive cooling system service package, it ensures correct coolant circulation, accurate temperature regulation, and reliable accessory belt operation. Ideal for preventative maintenance or full cooling system repair, this kit provides everything needed to restore confidence in your Porsche’s engine cooling performance.
The water pump continuously circulates coolant through the engine and radiators, while the thermostat regulates operating temperature and ensures the engine warms up properly. The serpentine belt drives essential accessories—including the water pump—so replacing all these components together ensures long-term reliability and prevents future breakdowns.
What This Complete Water Pump Kit Does
This cooling system service kit:
- Replaces
the water pump to restore proper coolant flow
- Includes
a new thermostat for accurate temperature control
- Supplies
a fresh serpentine belt to ensure reliable accessory drive operation
- Comes
with all required gaskets to prevent leaks during installation
- Improves
cooling efficiency, reducing the risk of overheating
- Ensures long-term reliability with coordinated component replacement
- Perfect for workshop servicing, DIY maintenance or high-mileage cooling system refreshes.
Why Water Pumps, Thermostats & Belts Fail
Common failure points include:
- Bearing
wear inside the water pump, causing leaks or noise
- Impeller
degradation, reducing coolant flow
- Thermostat
sticking, leading to overheating or overcooling
- Serpentine
belt cracking, glazing or stretching
- Coolant
contamination, accelerating component wear
- Heat cycling, which weakens gaskets and housings
Cooling failures can cause warped cylinder heads, engine misfires or complete engine failure if not addressed promptly.
Why These Components Should Be Replaced Together
Replacing the pump, thermostat and serpentine belt as a set
ensures:
- Restored cooling performance across the entire system
- Correct belt tension and accessory drive function
- Reduced labour costs by avoiding repeat disassembly
- Balanced
longevity, as all components age similarly
- Prevention
of leaks, thanks to new gaskets and seals
- Peace of mind for daily driving, long trips or track use
This kit offers the most reliable and cost-effective approach to cooling system maintenance.

Restore dependable coolant circulation and effective engine temperature control with this OE Match Replacement Water Pump with Gasket. Designed for compatible Porsche applications, the water pump is a critical component of the engine cooling system, circulating coolant between the engine, radiator and associated cooling circuits.
Fits:
- Porsche 955 Cayenne S 4.5L V8 2003-06
- Porsche 955 Cayenne Turbo 4.5L 2003-06
- Porsche 955 Cayenne Turbo S 4.5L 2006>>
As the engine produces heat, coolant absorbs that heat and carries it away from critical engine components. The water pump maintains the continuous circulation required for this process, allowing heat to be transferred through the radiator and helping the engine remain within its correct operating temperature range.
Water pumps are subjected to continuous rotational loads, heat cycles and coolant exposure. Over time, the internal bearing, mechanical seal or impeller can deteriorate, potentially resulting in coolant leakage, abnormal noise or insufficient coolant circulation.
This replacement is supplied with a gasket, providing the sealing component required between the water pump and its mating surface where applicable.
The OE Match Water Pump provides a high-quality replacement for a worn, leaking or failed original pump, helping restore reliable cooling-system performance.
What This Product Does:
- Circulates coolant through the engine cooling system.
- Moves heated coolant away from the engine.
- Helps transfer engine heat to the radiator.
- Supports stable engine operating temperatures.
- Helps prevent overheating caused by inadequate coolant circulation.
- Maintains coolant flow during normal engine operation.
- Supports effective cooling during demanding driving conditions.
- Works with the radiator, thermostat and associated cooling components.
- Replaces a leaking, noisy, worn or failed water pump.
- Is supplied with a gasket for the applicable sealing surface.
- Provides an OE-style replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Coolant leaking from around the water pump.
- Coolant stains or dried residue around the pump housing.
- Frequent loss of coolant.
- Engine temperature running higher than normal.
- Engine overheating.
- Temperature fluctuations during driving.
- Cooling-system warning messages.
- Grinding, rumbling or whining from the pump area.
- Excessive play in the water pump shaft or bearing.
- Coolant leaking from the pump's weep area.
- Visible damage or corrosion around the pump.
- Reduced coolant circulation.
- Steam or coolant smell from the engine compartment.
- Evidence of impeller deterioration or damage after removal.
Why Replacement Matters:
- The water pump is fundamental to engine temperature control. Without sufficient coolant circulation, heat cannot be transferred efficiently from the engine to the radiator.
- A leaking pump can gradually reduce the coolant level. As coolant is lost, the cooling system becomes less effective and air may enter the circuit, increasing the risk of unstable temperatures and overheating.
- Internal pump failure can be equally serious. A worn bearing may allow shaft movement that damages the mechanical seal, while a deteriorated or damaged impeller may reduce coolant circulation even if there is no obvious external leak.
- Continued operation with insufficient cooling can cause severe engine damage. Excessive temperatures can damage seals and gaskets, distort components and, in extreme cases, lead to major cylinder-head or engine repairs.
- A failing bearing can also eventually seize or allow excessive movement within the pump assembly, potentially affecting associated drive components depending on the engine configuration.
- Replacing a deteriorated pump with this OE Match Replacement Water Pump with Gasket helps restore correct coolant circulation, stable engine temperatures and dependable cooling-system operation.
