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.

Diagram ref no 3, 9, 11

This roller provides a smooth, low-friction contact surface for the timing belt, helping the belt run true and remain properly tensioned across engine speed and load changes.

Function:
• Maintains consistent timing belt tension and tracking
• Reduces belt noise/vibration and helps prevent premature belt wear
• Supports accurate engine timing by keeping belt control stable

A worn roller bearing can become noisy, develop play, or seize - leading to poor belt control and accelerated belt wear. Replacing the roller during timing belt service helps maintain dependable belt tension and reduces the risk of timing drive issues.

When to replace:
•  During timing belt replacement (recommended best practice)
•  Any sign of bearing noise (whine/rumble) from the timing area
•  Visible play, roughness, or contamination when spun by hand
•  Oil/coolant contamination in the belt area that may damage bearings

Engine Rebuild Belts, Tensioners & Rollers – Precision Timing for Reliable Porsche Performance

Engine rebuild belts, tensioners, and rollers are essential components in maintaining your Porsche’s precise engine timing and smooth operation. These parts work together to synchronise the camshaft and crankshaft, ensuring valves open and close at exactly the right time for optimal combustion. Over time, these components can wear or deteriorate, especially under high performance or extended use, making replacement vital during an engine rebuild or major service.

At Design911, we supply a full range of genuine and high-quality belts, tensioners, and rollers for various Porsche models including, 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is designed for strength, accuracy, and long-lasting reliability — ensuring your rebuilt Porsche engine performs flawlessly mile after mile.

What Do Engine Belts, Tensioners & Rollers Do?

These components form the heart of the engine’s timing and auxiliary systems. They:

  • Drive key engine components, including the camshaft, alternator, and water pump.
  • Maintain accurate timing for optimal combustion and efficiency.
  • Reduce friction and noise through smooth roller and tensioner operation.
  • Ensure consistent belt tension to prevent slippage or premature wear.

Together, they guarantee your Porsche’s engine runs smoothly, efficiently, and reliably — whether cruising or driving at peak performance.

Why Do Belts, Tensioners & Rollers Fail?

Exposure to high temperatures, vibration, and constant motion causes natural wear over time. Common causes of failure include:

  • Aging rubber belts becoming brittle or cracked.
  • Worn bearings in rollers or tensioners leading to noise or vibration.
  • Loss of tension causing belt slippage or timing misalignment.
  • Contamination from oil or coolant degrading materials.
  • Extended maintenance intervals leading to unexpected failure.

Symptoms of failing components include squealing noises, poor engine performance, rough idle, or even timing belt failure, which can cause severe engine damage if ignored.

Why Replace Belts, Tensioners & Rollers During an Engine Rebuild?

Replacing these components during an engine rebuild ensures long-term reliability and eliminates the risk of future timing-related failures. A fresh set of belts, rollers, and tensioners restores precision, efficiency, and performance — protecting your investment.

Benefits of replacement include:

  • Restored precise timing and smooth operation.
  • Reduced risk of catastrophic engine failure.
  • Enhanced reliability and longevity of the rebuild.
  • Quieter, more efficient engine performance.

All components available from Design911 are made using premium-grade materials, precision bearings, and advanced heat-resistant compounds, ensuring maximum durability and performance in high-stress Porsche engines.
