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.
