Common Problems This Radiator Can Address

• Coolant leaks from a damaged or aging radiator
• Overheating caused by restricted or inefficient heat transfer
• Cracked or brittle factory-style plastic tank assemblies
• Corrosion or internal wear in the original cooling core
• Poor fitment from non-OE-style replacement radiators

Installation Notes

Verify inlet and outlet orientation before installation: this radiator uses a left inlet and right outlet. Confirm core dimensions and mounting points against the original unit before removal. Inspect hoses, clamps, and the radiator cap specification during service; CSF cap number 4503 is listed for reference, and the cap is not included.

For best results, flush the cooling system and check for contamination before installing the new radiator. After installation, refill with the correct coolant mixture and bleed the system according to Hyundai service procedures.
