Parts alone typically range from about $120 to $600, with installed costs commonly between $350 and $1,000 depending on engine variant, radiator type (OEM vs aftermarket), and labor rates.
What affects the price
Several factors drive the overall cost of a radiator replacement for a 2006 Chrysler 300C, including engine type (3.5L V6 vs 5.7L Hemi), radiator construction, and whether you choose an OEM Mopar part or an aftermarket alternative.
Key factors to consider
- Engine and radiator compatibility: The 300C came with different engines across model years, and radiators are designed to fit specific configurations. Verify compatibility with your VIN.
- Radiator material and design: Aluminum cores with plastic tanks are common and typically lighter and cheaper than copper/brass variants, though some high-performance options exist.
- OEM vs aftermarket: OEM/Mopar radiators tend to be more expensive but offer guaranteed fit and warranty; aftermarket options can be cheaper and offer similar cooling performance.
- New vs used or remanufactured: New radiators are the most reliable but costliest; used or remanufactured units can save money with varying warranty terms.
In short, the smallest difference is often whether you buy OEM versus aftermarket, while the largest impact comes from engine-specific radiator design and any bundled components.
Prices by source
Prices vary by seller and vehicle specifics; the ranges below reflect typical retail pricing seen at major outlets and online marketplaces as of 2024–2026.
- OEM Mopar or dealer-part radiators: typically $250–$600

- Used or remanufactured radiators: typically $50–$200
Note that compatibility (engine variant and year), warranty terms, and shipping can influence the final price. Always confirm part numbers with your VIN before purchasing.
Installation and total cost estimates
Professional installation costs can vary by region and shop, and may include coolant, hoses, clamps, and potential thermostat or fan work. The figures below are typical ranges for 2024–2026 estimates.
- Labor to replace the radiator: approximately $200–$500
- Additional parts and fluids (hoses, clamps, coolant, thermostat, shroud): $20–$120
- Total installed cost: typically $350–$1,000, with higher-end aluminum radiators or complex cooling-system issues pushing beyond this range
Get a detailed, written estimate that separates parts and labor, and asks about any diagnostic or disposal fees.
Where to buy and how to decide
Consider both brick-and-mortar auto parts stores and reputable online retailers. Use your vehicle VIN to confirm exact compatibility, and compare prices, warranties, and return policies across several sources.
What to expect from installation
Expect the replacement to take roughly 1.5 to 3 hours at a typical shop, plus time for a coolant flush and refill. Complications such as seized hoses or a leaking cooling system can extend the job.
Summary
For a 2006 Chrysler 300C, radiator replacement costs vary widely based on engine configuration, part origin, and labor rates. Plan for part prices around $120–$600 and total installed costs roughly $350–$1,000, with OEM parts and premium setups at the higher end. Always verify VIN-compatible parts, request a written estimate, and shop around to balance price, fit, and warranty.
