Our guide covers 9 model years for the Mercedes S Class (2015–2024) but only 6 for the Cadillac CT5 (2020–2025), so the Mercedes S Class data reflects a broader range of generations.
The Mercedes S Class radiator is interchangeable across 15 model years versus just 7 for the Cadillac CT5 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.

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.
