Details on the 1 Row Plastic Tank Aluminum Core Product Line

The CSF 1 Row Plastic Tank Aluminum Core line combines an aluminum core with OEM-style plastic tanks to provide a balance of lightweight construction and durability. This product line is engineered to meet original equipment specifications, ensuring compatibility and performance for vehicles like the Mini Cooper series. The single-row core design supports efficient cooling while maintaining a compact form factor suitable for tight engine bays.

Product Description and Specifications

The CSF 3429 radiator features a 5/8 inch thick aluminum core measuring 16 5/16 inches wide and 23 5/8 inches long. Its cross flow configuration allows coolant to move horizontally through the core, enhancing heat exchange efficiency. The plastic tanks on either side are designed to resist corrosion and reduce weight compared to metal tanks. The inlet and outlet ports both measure 1 3/8 inches in diameter, positioned on the left and right sides respectively, facilitating straightforward hose connections. This radiator is a direct replacement part for Mini Cooper, Cooper Countryman, and Cooper Paceman models, ensuring proper fit and function.

Common Applications and Issues Addressed

  • Replacement for leaking or cracked radiator tanks
  • Resolution of overheating caused by clogged or damaged cores
  • Upgrade to OEM-style aluminum core for improved cooling efficiency
  • Fixes coolant flow restrictions due to radiator core damage
  • Restores proper engine temperature regulation in Mini Cooper vehicles

Installation Notes and Tips

When installing the CSF 3429 radiator, ensure all coolant hoses match the 1 3/8 inch inlet and outlet diameters for a secure fit. Since the radiator does not include a cap, reuse the existing cap or source a compatible replacement. Verify the cross flow orientation aligns with your vehicle’s cooling system layout. Properly bleed the cooling system after installation to prevent air pockets and ensure optimal performance.
