The Mercedes C Class average ($392) runs 46% above its median ($269), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 9 model years for the Mercedes C Class (2018–2026) but only 4 for the Kia Optima (2015–2020), so the Mercedes C Class data reflects a broader range of generations.
The Kia Optima radiator is interchangeable across 15 model years versus just 11 for the Mercedes C Class — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Kia Optima is 49% cheaper ($153 vs $298) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used radiator
- Inspect for bent or crushed fins — minor cosmetic bending is OK, but large crushed sections reduce cooling capacity.
- Check both tanks (top and bottom) for cracks, especially along the crimped seams on plastic-tank radiators.
- Confirm the inlet/outlet positions and sizes match — some models moved ports between model years.
- Look for internal blockage: shake the unit and listen for debris, or flush it with a garden hose before installing.
