Detailed Product Description

The CSF 3914 radiator is engineered specifically for Hyundai Accent and Kia Rio vehicles, ensuring compatibility and reliable fitment. Its aluminum core with a 5/8 inch thickness provides efficient heat transfer, helping maintain optimal engine temperatures. The plastic tanks reduce weight while maintaining structural integrity. The cross flow design promotes effective coolant circulation, enhancing overall cooling system performance. The radiator features a single core row, balancing cooling capacity with compact size. Inlet and outlet diameters are precisely sized for direct replacement, simplifying installation. Additionally, the integrated high-efficiency plate type oil cooler supports engine oil temperature regulation, contributing to engine longevity.

Common Applications and Issues Addressed

  • Replacement for leaking or cracked radiators in Hyundai Accent and Kia Rio
  • Resolves overheating issues caused by inefficient cooling
  • Addresses coolant flow restrictions due to clogged or damaged cores
  • Improves engine oil cooling with integrated oil cooler for better performance
  • Restores proper coolant circulation in vehicles with damaged or worn radiators

Installation Notes and Tips

When installing the CSF 3914 radiator, ensure all coolant hoses match the specified inlet and outlet diameters (1 3/8 inch left inlet, 1 5/16 inch right outlet) for a secure fit. Verify the cross flow orientation aligns with the vehicle’s cooling system layout. 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.
