belt tensioning damper Genuine Porsche part 95510229900

Accessory Drive Belt Kit (Serpentine Belt Kit)
This kit includes everything needed to replace the primary wear components of your accessory drive system. Each kit comes complete with a new serpentine belt, drive belt tensioner shock, tensioner pulley, two idler pulleys, and all required hardware.

The accessory drive belt—commonly known as a serpentine belt—delivers power from the engine’s crankshaft to essential components such as the alternator, water pump, power steering pump, and air conditioning compressor. It drives these systems through a network of pulleys synchronized by the belt’s rotation.

Regular inspection of the belt is important. Look for cracking, fraying, glazing, or other signs of wear. Most manufacturers recommend replacing the belt every 50,000 to 100,000 miles. Proper belt tension is equally critical, so it’s advisable to inspect the belt tensioner and idler pulleys any time the belt is serviced.

Symptoms of Accessory Drive Belt Kit Failure

• Wear and Tear: Cracking, glazing, or fraying can cause the belt to slip. 
•   Pulley Misalignment: Misaligned pulleys lead to uneven wear and unwanted noise. 
•   Improper Tension: Too much or too little tension can result in belt slip or premature component failure. 
•   Contamination: Oil, coolant, or debris can weaken the belt material. 
•   Excessive Noise: A squealing sound, especially at start-up, often indicates belt or tensioner issues.

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 957 Cayenne S/GTS 4.8L 2007-10
• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10

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
  
  

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.
