The cost to replace a thermostat on a Chrysler 300 typically falls in the hundreds of dollars, with most drivers paying around the low to mid hundreds depending on engine type, parts, and labor. In practice, you’ll see a broad range, but a typical repair sits around $180 to $350 for many models.
Cost components you should expect
The total price is usually a combination of parts, labor, and any necessary coolant service. Here is what tends to drive the bill.
- Parts: thermostat plus gasket or O-ring, and any coolant needed for a refill. Thermostats can be aftermarket or OEM; expect roughly $15–$60 for the thermostat, $5–$15 for the gasket, and about $5–$20 for coolant.
- Labor: most Chrysler 300 thermostat jobs take about 1 to 2 hours of labor, with shop rates commonly around $80–$150 per hour (dealer rates can be higher).
- Coolant and disposal: if coolant is drained and refilled, expect a small charge for coolant and disposal, typically $5–$25.
- Additional services (optional): some shops will perform a pressure test, bleed the cooling system, or inspect hoses, which can add $20–$60.
Concluding: The overall bill reflects parts quality, how long the job takes, and whether extra coolant work or inspections are included. Most customers should budget within the low-to-mid hundreds, depending on the factors above.
Engine variants and cost implications
The exact engine configuration in your Chrysler 300 can influence labor time and thus total cost, even though the thermostat replacement procedure is similar.
- 3.6L Pentastar V6: This is the most common engine in recent Chrysler 300 models. Expect total costs in the ballpark of $180–$350, depending on local labor rates and whether coolant service is included.
- 5.7L Hemi: Found in some older or performance-oriented trims. Total costs commonly range from about $200–$450, particularly if OEM parts or dealer service are used or if more labor time is required.
Concluding: While the thermostat itself is a relatively simple part, the accessibility in the engine bay and the shop’s labor rate can push the price up or down by engine type and service package.
Practical tips for getting a good deal
To avoid surprises, request itemized quotes and compare several shops. Ask whether coolant service is included, whether a pressure test is performed, and what warranty covers parts and labor.
Summary: Replacing a Chrysler 300 thermostat generally costs between roughly $180 and $450, with most cases landing in the $250–$350 range. Key factors include engine type (3.6L vs. 5.7L), parts choice (OEM vs. aftermarket), local labor rates, and whether coolant service or extra inspections are bundled into the job. Always obtain an itemized quote and consider independent shops for best value.
