Product Line Details: 1 Row Plastic Tank Aluminum Core

The 1 Row Plastic Tank Aluminum Core product line by CSF combines lightweight plastic tanks with a robust aluminum core to provide a balance of durability and efficient cooling. This design supports cross flow coolant movement, which enhances heat exchange and maintains optimal engine temperatures.

This radiator features a 1 1/4 inch thick aluminum core measuring 16 7/8 inches wide and 24 15/16 inches long, configured in a single core row. The cross flow design allows coolant to pass horizontally through the core, improving heat dissipation efficiency.

Installation Notes and Tips

When installing the CSF radiator part number 3452, ensure compatibility with your Audi model's cooling system connections, especially the quick-connect inlet. Verify inlet and outlet hose diameters and positions to match the vehicle's specifications. Since the radiator does not include a cap, reuse the existing radiator cap or source a compatible replacement. Properly bleed the cooling system after installation to prevent air pockets and ensure optimal performance.
