This comprehensive kit allows you to replace the entire radiator system in one installation, ensuring optimal cooling performance and reducing the risk of future leaks or component failures.

Cross Reference Numbers

• LEFT: 99610613172 / 99610613174
• RIGHT: 99610613270 / 99610613272
• CENTRE: 99610603751 / 99610603752 / 99610603752

What This Radiator Kit Does

The Porsche 996 turbo / GT2 cooling system relies on three front-mounted radiators to dissipate heat from the engine coolant. These radiators maintain stable engine operating temperatures by transferring heat away from the coolant through airflow across the radiator core.

A properly functioning radiator system helps:

• Prevent engine overheating
• Maintain optimal engine performance
• Protect cylinder heads and gaskets
• Improve cooling during heavy traffic or hot weather
• Support track and performance driving conditions

Why Porsche 996 Radiators Fail

Over time, original radiators can suffer from:

  • Road debris damage
  • Corrosion and coolant contamination
  • Plastic end tank fatigue
  • Blocked cooling cores

Replacing all three radiators together ensures balanced cooling performance and prevents repeated labour costs.

About Radiators

Porsche Performance Radiators - Engine Cooling & Thermal Control Upgrades

Radiators are a critical part of the engine cooling system, responsible for dissipating heat and maintaining optimal operating temperatures. In performance-driven, tuned, or high-mileage Porsche engines, upgraded radiators play a vital role in preventing overheating, reducing thermal stress, and protecting engine components under sustained load.

Available from Design911, Porsche performance radiators are engineered to deliver increased cooling efficiency, improved airflow, and enhanced durability—making them essential upgrades for road, track, and high-performance applications.

What Do Radiators Do?

Radiators regulate engine temperature by transferring heat away from the coolant.

Core Functions:

  • Dissipate engine heat efficiently.
  • Maintain stable operating temperatures.
  • Prevent overheating under load.
  • Support consistent engine performance.
  • Protect internal engine components from heat damage.

Effective cooling is essential for engine reliability and longevity.

Why Do Radiators Fail?

Standard radiators can degrade over time due to age, contamination, and increased thermal demand. Common failure causes include:

  • Internal blockage from debris or sediment.
  • External fin corrosion or damage.
  • Coolant leaks from plastic end tanks or seals.
  • Reduced efficiency due to age and contamination. 
  • Increased heat load from tuned or track-driven engines.

A failing radiator can lead to overheating, coolant loss, and serious engine damage if left unresolved.

Why Upgrade to a Performance Radiator?

Performance radiators are designed to handle higher thermal loads more effectively.

Upgrade Benefits:

  • Increased cooling capacity and heat dissipation.
  • Improved airflow and coolant flow efficiency.
  • Stronger materials for enhanced durability.
  • Reduced risk of overheating during spirited or track driving.
  • Ideal upgrade for tuned and high-output engines.

Upgrading the radiator helps protect engine reliability while supporting performance enhancements.

Highlights

  • Porsche performance radiator upgrades
  • Improved cooling efficiency and heat management
  • Designed for tuned and high-performance engines
  • Enhanced durability and long service life
  • Essential upgrade for track and performance use
