Complete Water Pump Kit – Water Pump, Thermostat, Serpentine Belt & Gaskets for a Full Cooling System Refresh
This complete water pump kit includes a new water pump, thermostat, drive (serpentine) belt and the required gaskets for both the pump and thermostat housing.

Fits:

  • Porsche Boxster 987 MKII 2.9L 2009-2012
  • Porsche Boxster S 987 MKII 3.4L 2009-2012
  • Porsche 997 MKII Carrera C2 3.6L 2009-12
  • Porsche 997 MKII Carrera C4 3.6L 2009-12
  • Porsche 997 MKII Carrera C2S 3.8L 2009-12
  • Porsche 997 MKII Carrera C4S 3.8L 2009-12
  • Porsche Cayman 2.9L 987C MKII 2009-12
  • Porsche Cayman S / R 3.4L 987C MKII 2009-1
  • Porsche Boxster 987 MKII 2.9L 2009-2012
  • Porsche Boxster S 987 MKII 3.4L 2009-2012
  • Porsche 997 MKII Carrera C2 3.6L 2009-12
  • Porsche 997 MKII Carrera C4 3.6L 2009-12
  • Porsche 997 MKII Carrera C2S 3.8L 2009-12
  • Porsche 997 MKII Carrera C4S 3.8L 2009-12
  • Porsche Cayman 2.9L 987C MKII 2009-12
  • Porsche Cayman S / R 3.4L 987C MKII 2009-12 

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.

About Water / Coolant Pumps

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.


Porsche Water Pumps: Common Issues, Fixes, and Upgrades #porsche #porscheparts #porscheupgrade

In this tech talk, Lawrence from Design 911 breaks down everything you need to know about water pumps for Porsche models. From the iconic 911 to the Cayenne and Macan, discover why the water pump is one of the most crucial components in your car’s cooling system. 

Learn how water pumps work, the common signs of failure, and why regular replacement is essential to avoid catastrophic engine damage.

Whether you're maintaining your Porsche or considering a water pump upgrade, this video covers original and aftermarket options, as well as the pros and cons of plastic vs. metal impellers. Watch now to keep your Porsche running at its best!
