Water / Coolant Radiators

Aluminium Water Coolant Radiators & Air Conditioning Condenser Kit

Completely refresh your Porsche's cooling and climate control system with this CSF Aluminium Water Coolant Radiator & Air Conditioning Condenser Kit. Combining CSF's industry-leading cooling technology with OEM+ fitment, this complete kit delivers improved engine cooling, enhanced air conditioning performance and exceptional long-term reliability.

Fits:

• Porsche 996 C4S 3.6L 09/01-2005
• Porsche 996 TURBO 2000-05
• Porsche 996 GT2 2001-05
• Porsche 997 MK1 TURBO 2007-09
• Porsche 997 MK1 GT2 2007-09
• Porsche 997 MKII Turbo 2010-13
• Porsche 997 MKII GT2 RS 2011-13

As the Porsche 996 turbo, GT2, C4S and 997 turbo 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.

• Circulates coolant between the engine and radiator.
• Dissipates engine heat through the radiator assembly.
• Maintains stable engine operating temperatures.
• Replaces ageing or damaged coolant pipes and connections.
• Helps preserve cooling system pressure and efficiency.
• Supports proper thermostat and water pump operation.
• Protects the engine from overheating and heat-related damage.
• Restores overall cooling system reliability.

• Coolant leaks beneath the vehicle.
• Low coolant level warnings.
• Engine overheating or rising temperature readings.
• Visible corrosion on radiator or coolant pipes.
• Cracked, swollen or deteriorated coolant hoses.
• Coolant residue around pipe connections and fittings.
• Sweet coolant odour from the engine bay.
• Reduced heater performance.
• Frequent need to top up coolant levels.
• Cooling system pressure loss.

• The cooling system is essential for maintaining correct engine operating temperatures and preventing excessive heat build-up. Over time, radiators, coolant pipes, hoses and fittings can deteriorate due to heat cycles, vibration, corrosion and exposure to coolant chemicals.
• A leaking or restricted cooling system can reduce heat transfer efficiency, causing engine temperatures to rise and increasing the risk of overheating. If left unresolved, cooling system failures can result in warped cylinder heads, damaged gaskets, reduced engine performance and potentially catastrophic engine damage.
• Replacing worn cooling system components with a complete radiator and pipe kit restores efficient coolant circulation, improves cooling performance and helps prevent costly repairs caused by overheating.
