Detailed Product Description

The CSF radiator 3885 is engineered with an OEM-style plastic tank and aluminum core, ensuring compatibility and performance for Kia Optima vehicles. The cross flow design allows coolant to flow horizontally through the core, improving heat exchange efficiency. With a core thickness of 7/8 inch and core dimensions of 18 5/16 inches in both width and length, this radiator balances cooling capacity with compact size. The inlet and outlet ports, each measuring 1 3/8 inches in diameter and positioned on the left and right respectively, facilitate proper coolant circulation. This radiator is a single-row core type, suitable for standard cooling system configurations without integrated oil coolers.

Compatible Applications and Common Issues Addressed

  • Replacement for damaged or leaking radiators in Kia Optima models
  • Resolves overheating caused by inefficient or clogged radiator cores
  • Addresses coolant leaks from cracked plastic tanks
  • Improves cooling system performance after radiator core corrosion
  • Suitable for restoring factory cooling specifications in Kia Optima vehicles

Installation Notes and Tips

When installing the CSF radiator 3885, ensure the inlet and outlet hose connections match the 1 3/8 inch diameter ports on the left and right sides respectively. Verify that the radiator core dimensions fit within the engine bay space of the Kia Optima. 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 coolant flow.
