Questions and Answers

Can part 25310-C1100 be used on Hyundai Sonata Hybrid or Plug-in Hybrid models?
No. Hybrid and plug-in hybrid variants incorporate complex electronic cooling loops, specialized inverter cooling channels, and distinct mounting layouts that require a dedicated hybrid-specific radiator assembly.
What is the difference between part numbers 25310-C1100, 25310-C1150, and 25310-D4000?
These numbers correspond to minor production revisions, factory updates, or regional specification adjustments (such as differing internal transmission oil cooler port sizes or auxiliary sensor fittings) across the Sonata LF and Optima JF life cycles.
How do I verify that this radiator matches my specific Sonata or Optima build?
Because mid-size sedans feature various drivetrain configurations and regional trim packages, we strongly recommend sending your chassis number (VIN) via our WhatsApp link to ensure accurate fitment before installation.
