This part cross-references Spectra Premium CU2831 for the same application.

What It Helps Address

• Overheating caused by a leaking or restricted radiator
• Coolant loss from cracked plastic tanks or aged seams
• Reduced heat transfer from a worn aluminum core
• Transmission cooling concerns on vehicles using the integrated oil cooler
• Fitment issues when replacing an OE-style Hyundai Azera or Hyundai Sonata radiator

Installation Notes

Verify radiator dimensions, inlet and outlet orientation, and oil cooler connection layout before installation. CSF 3188 uses a cross-flow configuration with the inlet on the right and outlet on the left, so matching the original routing is important for proper installation. Confirm the vehicle’s cap and cooling system specifications against the listed OE-style design notes before final assembly.

Quality Assurance

CSF states that its factories are ISO/TSO certified and that its radiators are engineered and tested for cooling performance validation. The brand also notes a catalog of more than 10,000 radiator models and decades of global supply experience, supporting consistent OE-style replacement coverage for applications such as the Hyundai Azera and Hyundai Sonata.
