CSF High-Performance All-Aluminum Radiator (CSF Part #7001)
Durable Construction. Reliable Cooling. Street & Track Ready.
The radiator is the foundation of your vehicle’s cooling system—responsible for keeping coolant temperatures stable, even under extreme driving conditions. The CarBahn High-Performance Radiator, based on CSF’s proven aluminum core design, offers a robust solution for aging or underperforming factory units. Whether you're preparing for spirited road use or hard track sessions, this upgrade ensures consistent thermal control and long-term reliability.
Key Features:
-
All-Aluminum TIG-Welded Construction – Replaces OEM plastic end tanks with high-strength TIG-welded aluminum for maximum durability.
-
Increased Cooling Efficiency – Optimized core and fin design promotes better airflow and more effective heat dissipation.
-
Direct Replacement Fitment – Designed for easy bolt-in installation using factory mounting points and fittings.
-
OEM-Compatible Connections – Integrates seamlessly with factory hose layouts and accessories.
-
Built to Last – Designed to handle the high pressures and repeated heat cycles of performance driving.
Why Upgrade Your Radiator?
Factory radiators often become weak links as vehicles age. Plastic end tanks can crack, fins become bent or clogged, and internal flow is reduced by debris buildup—all leading to higher operating temps and reduced engine efficiency. Replacing your radiator with a high-performance all-aluminum unit restores cooling performance and helps protect the engine from overheating-related damage.
Signs of Radiator Failure
-
Engine Overheating
-
Coolant Leaks around fittings or under the vehicle
-
Cracked End Tanks from heat cycling or age
-
Bent or Clogged Fins reducing airflow and thermal performance
CarBahn Recommendation
To ensure full system integrity, we recommend replacing the upper and lower radiator hoses during radiator installation. A compromised hose can quickly lead to coolant loss or system pressure failure—even with a brand-new radiator in place.
