Market analysis
Why does the Mercedes S Class radiator cost more?
A used Mercedes S Class radiator carries a median asking price of $200, which is 45% higher than the Acura RDX at $138. Supply also plays a role: Mercedes S Class has 5,325 priced listings versus 445 for Acura RDX, and more listings generally mean more choices and more competitive pricing.
The Acura RDX average ($160) runs 16% above its median ($138), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 11 model years for the Acura RDX (2015–2025) but only 9 for the Mercedes S Class (2015–2024), so the Acura RDX data reflects a broader range of generations.

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.
