What These Radiators Kit Do
The Porsche 718 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 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.
Why Upgrade to CSF Performance Radiators?
All-Aluminium Motorsport Construction
CSF radiators are engineered using full aluminium construction with precision
welding and reinforced joints, improving strength and durability compared with
standard replacements.
High Efficiency Core Design
The advanced 2-row core with CSF B-Tube technology increases cooling capacity
by approximately 20 percent compared with conventional radiator tube designs.
True Drop-In Installation
Designed as OE-specific replacements with correct mounting points and
quick-connect inlet and outlet pipes for easy installation without
modification.
Track-Tested Reliability
These radiators have been tested under extreme conditions, including high
ambient temperatures and track environments.
Engineering Highlights
• B-Tube technology for maximum heat transfer efficiency
• High efficiency louvered fin design
• OE radial and deep drawn aluminium end tanks
• Wind tunnel tested core for optimal airflow cooling
• Reinforced mounting design for fan shrouds and condensers
• CNC machined brackets and fittings
• Racing style all aluminium drain plug
• Direct OE fitment requiring no modifications
Manufacturing Quality
• Brazed in CAB furnace for strength and consistency
• ISO 9001 / ISO 9002 certified production
• Dedicated in-house tooling and engineering facilities
• Master-class TIG welding for precision joints
Testing and Quality Control
• Individual leak testing
• Vibration cycle testing
• Thermal cycle testing
• Burst pressure testing repeated 10,000 times
• Salt spray corrosion resistance testing
