Key factors that affect price and fit
Understanding what drives price helps you avoid surprises and pick the right unit for your Chrysler 300. Consider these factors when shopping.
- Engine type and compatibility (3.5L V6 vs 5.7L Hemi) determine the exact radiator model and inlet/outlet configuration.
- Core size and material (aluminum core with plastic tanks is standard today; copper/brass cores are rare in newer designs).
- Presence of cooling fans and shrouds (radiators sold with fans or fan assemblies cost more).

- Shipping costs and seller location (centralized warehouses and free shipping can affect total delivered price).
When in doubt, compare part numbers and verify fit with your VIN before purchasing to ensure correct geometry and hose connections.
