As Porsche 997 and 987 models continue to age, corrosion, blocked cooling fins and road debris can significantly reduce the efficiency of both the engine cooling system and the air conditioning condensers. Replacing these components together restores cooling performance throughout the vehicle while reducing future labour costs and helping prevent overheating or air conditioning failures.
This complete upgrade package is ideal for road cars, fast-road builds, track day vehicles and full restorations.
Kit Contents
This complete cooling package includes:
- 2 x CSF OEM+ Performance Air Conditioning Condensers
- 1 x CSF Aluminium Left Water Coolant Radiator
- 1 x CSF Aluminium Right Water Coolant Radiator
Together these components provide a complete front-end cooling system upgrade using premium CSF Performance products.
Why Replace the Cooling System Together?
The front-mounted radiators and air conditioning condensers
are constantly exposed to:
- Road debris.
- Stone impacts.
- Moisture.
- Corrosion.
- Leaves and dirt blocking airflow.
Even when they appear externally clean, internal corrosion and blocked cooling passages can significantly reduce cooling efficiency.
Replacing all four units together provides:
- Maximum engine cooling performance.
- Improved air conditioning efficiency.
- Better airflow through the front cooling pack.
- Reduced coolant temperatures.
- Improved refrigerant heat dissipation.
- Increased long-term reliability.
- Lower overall installation costs compared with replacing components individually.

The radiator’s main role is to remove heat from the engine coolant that carries thermal energy away from the engine block and cylinder head. Hot coolant flows into the radiator, where it travels through a series of fine tubes and cooling fins. Air passing through the radiator core (from vehicle motion and fans) absorbs the heat, lowering coolant temperature before it returns to the engine.
Proper heat rejection helps:
• Maintain optimal engine operating temperature
• Prevent overheating under everyday and high-load conditions
• Support fuel efficiency and emission control
• Preserve engine component durability and longevity

Water Coolant Radiators – Efficient Cooling Performance for Porsche Engines
Water coolant radiators are the heart of your Porsche’s cooling system, responsible for maintaining the perfect balance between performance and engine temperature. These components dissipate heat from the coolant as it passes through the radiator core, ensuring your engine operates at peak efficiency while preventing overheating - whether you’re cruising through city streets or pushing hard on the track.
At Design911, we offer a comprehensive range of genuine and high-quality water coolant radiators for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, Panamera and transaxle cars. Each radiator is precision-engineered to provide efficient heat exchange, corrosion resistance, and a perfect fit, ensuring long-lasting performance and reliability for every driving condition.
What Do Water Coolant Radiators Do?
Radiators are essential to your Porsche’s engine cooling
system. Their primary functions include:
- Transferring
heat from the coolant to the surrounding air.
- Regulating
coolant temperature to prevent engine overheating.
- Supporting
overall thermal balance for performance and emissions efficiency.
- Enhancing reliability by maintaining optimal operating temperatures in all climates.
By efficiently dissipating heat, radiators protect your engine, prevent premature wear, and maintain consistent performance under pressure.
Why Do Radiators Fail?
Despite being built for endurance, radiators experience
constant thermal stress, exposure to pressure, and environmental elements that
can lead to failure. Common causes include:
- Corrosion
or rust due to contaminated or old coolant.
- Leaks
from cracked tanks, damaged cores, or failing seals.
- Blockages
caused by debris or scale build-up inside coolant passages.
- Physical
damage from road debris or stone impacts.
- Coolant contamination from oil or combustion residue.
Symptoms of radiator failure include overheating, coolant loss, visible leaks, or fluctuating temperature readings.
Why Replace a Faulty Radiator?
A damaged or inefficient radiator compromises your Porsche’s cooling system, risking overheating and potential engine damage. Replacing your radiator with a high-quality, manufacturer-standard unit ensures optimal cooling efficiency, reliability, and peace of mind.
Benefits of replacement include:
Restored
cooling efficiency and heat dissipation.
Prevention
of engine overheating and coolant loss.
Enhanced
vehicle performance and fuel economy.
Durable,
corrosion-resistant materials for long service life.
All radiators in our range are designed using premium aluminium cores, precision welds, and reinforced end tanks to ensure excellent cooling capacity, leak prevention, and long-term reliability — perfect for both standard and high-performance Porsche applications.
