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.

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.

Water / Coolant Pumps – Reliable Engine Cooling for Porsche Vehicles
Water / coolant pumps are at the heart of your Porsche’s cooling system. Their job is to circulate coolant through the engine, radiator, and heater core, maintaining the correct operating temperature and preventing overheating. A properly functioning water pump ensures efficient heat transfer, optimal performance, and long-term engine reliability.
At Design911, we supply a wide range of genuine and high-quality water pumps for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, Panamera and the transaxle cars. Each pump is precision-engineered to deliver consistent coolant flow, high durability, and dependable performance - ensuring your Porsche’s engine stays cool under all driving conditions.
What Do Water Coolant Pumps Do?
Water pumps are a critical
part of your engine’s temperature control system. They:
- Circulate coolant between the engine block, radiator, and heater system.
- Regulate temperature by dispersing heat efficiently throughout the system.
- Maintain coolant pressure for consistent engine operation.
- Support performance and longevity, preventing damage from excessive heat.
Without a properly working water pump, coolant circulation stops — leading to overheating, loss of performance, and potential engine failure.
Why Do Water Coolant Pumps Fail?
Even the most durable water
pumps can fail over time due to heat, age, and coolant contamination. Common
causes of failure include:
- Bearing wear or seal leaks caused by prolonged use or poor coolant quality.
- Corrosion or pitting from old or incompatible coolant mixtures.
- Cracked impellers or worn components reducing flow efficiency.
- Coolant leaks around the housing or pulley.
- Age-related wear, especially in high-mileage vehicles.
Signs of failure include visible coolant leaks, high engine temperature, whining noises from the pump area, or reduced cabin heating.
Why Replace a Faulty Water Coolant Pump?
A failing water pump can cause severe engine overheating, loss of coolant, or total breakdown. Replacing a worn pump restores reliable cooling and helps protect your engine from costly damage.
Benefits of
replacement include:
- Restored coolant circulation and cooling efficiency.
- Improved engine reliability and performance.
- Prevention of leaks, overheating, and corrosion.
- Long-lasting, high-quality construction for dependable operation.
All water pumps in this range are built using high-strength materials, precision impellers, and sealed bearings designed to deliver durability, quiet operation, and efficient coolant flow over time.
