Detailed Product Description

The CSF 3915 radiator is engineered with a 1 1/4 inch thick aluminum core that provides efficient heat transfer to maintain optimal engine temperatures. Its cross flow design allows coolant to move horizontally through the core, improving cooling performance for Hyundai Soul and Kia Veloster vehicles.

This radiator core features a single row, balancing cooling capacity with compact size. The overall core length and width are 25 9/16 inches and 11 5/16 inches, respectively, ensuring a precise fit for the intended models.

  • Resolves overheating problems caused by inefficient cooling systems
  • Addresses coolant flow restrictions due to clogged or damaged radiator cores
  • Suitable for vehicles requiring OEM style radiator core and tank materials
  • Ideal for restoring proper engine temperature regulation after radiator failure

Installation Notes and Tips

When installing the CSF radiator 3915, ensure all coolant hoses match the 1 3/8 inch inlet and outlet diameters for a secure fit. Verify the cross flow orientation aligns with the vehicle’s cooling system layout. It is recommended to flush the cooling system before installation to prevent contamination. Check for proper mounting points and secure the radiator firmly to avoid vibrations. Since the radiator does not include a cap, reuse the existing cap or source a compatible replacement.
