For a 2006 Chrysler 300, the thermostat part itself typically costs about $8 to $60, depending on brand and whether you buy aftermarket or OEM. When you include installation, most customers pay around $150 to $350 total, with higher costs possible for premium OEM parts or difficult engine layouts.
The 2006 Chrysler 300 offered several engine options, and the exact thermostat model can vary by engine. Replacement involves draining and refilling coolant, and costs depend on part type (thermostat alone vs housing kit), supplier, and local labor rates. This article breaks down typical costs and shopping tips to help you estimate your total.
Part price ranges
Prices vary by brand and whether you need just the thermostat or a housing-equipped kit.
- Aftermarket thermostat (no housing): typically $8–$25.
- OEM Mopar thermostat (no housing): typically $20–$60.
- Thermostat kit with housing or includes gaskets/o-rings: typically $40–$100.
In short, the part itself is usually the least expensive portion of the total, and buying the housing with the thermostat can push the price up by about $20–$60 depending on brand and where you shop.
Labor and total installed cost
Installation costs depend on how accessible the thermostat is and local labor rates; the typical process takes about 1–2 hours on most 2006 Chrysler 300 engines, though some configurations may require more time.
- Labor cost: at typical shops, around $75–$125 per hour; total labor often ranges from about $75 to $250.
- Coolant replacement/replenishment: about $10–$30 for premixed coolant (some shops include this in the service).
- Miscellaneous fees (shop supplies, disposal, etc.): vary by shop.
Conclusion: A standard thermostat replacement in a 2006 Chrysler 300 typically totals around $150–$350, with higher prices if the engine is hard to access or you choose premium OEM parts at a dealership.
Where to shop and what to check
Before buying, compare prices across several sources and ensure compatibility with your exact engine variant and VIN. Consider OEM vs reputable aftermarket brands; check if the kit includes the gasket and hose clamps; verify whether coolant needs to be flushed or simply topped off after replacement.
- Sources: local auto parts stores, dealer service departments, and online retailers (e.g., RockAuto, AutoZone, Advance Auto).
- What to buy: thermostat alone or a kit with housing and gaskets; confirm the correct part number for your engine.
- Warranty: aftermarket thermostats often include a limited warranty; OEM parts may have longer coverage.
Conclusion: Shopping around and confirming the exact part fitment for your engine can save money and prevent installation issues.
