How much is it to replace a thermostat on a 2012 Dodge Avenger?

The typical total price for replacing a thermostat on a 2012 Dodge Avenger is about $150 to $350, including parts and labor.


Prices vary by region and shop, and can be higher if other cooling-system components—such as the water pump or hoses—need replacement or if OEM parts are chosen. The job usually requires draining and refilling coolant, bleeding air from the system, and resealing the thermostat housing.


What affects the cost?


Costs come from several sources; here is a typical breakdown of what you might see on a list of charges:



  • Parts: thermostat kit and gasket; aftermarket parts typically cost about $15–$60, while OEM parts may be more expensive. Coolant may also be needed and typically runs about $5–$15.

  • Labor: about 1–2 hours of shop time, with regional labor rates commonly $75–$125 per hour (higher in urban areas).

  • Coolant and disposal: often included in the estimate, but sometimes billed separately (roughly $5–$15).

  • Shop fees, taxes, and miscellaneous: about $5–$25.

  • Possible extra work: if the cooling system has other issues (leaking hoses, worn water pump, or a failing radiator), expect an additional $100–$500+ depending on parts and labor.


In many cases, a straightforward thermostat replacement without other issues lands in the $150–$350 range, but the total can rise if other cooling-system repairs are needed.


DIY vs professional service


When DIY makes sense


If you have basic mechanical skills, the right tools, and can safely drain and refill coolant, you can save on labor costs. Plan for a fresh coolant fill and a careful bleed to prevent air pockets.


When to leave it to a pro


If you're not comfortable with cooling-system work, or if you suspect other issues (such as overheating or a leaking hose), a professional shop can diagnose and complete the job correctly, often with a warranty on labor.


Summary


Bottom line: for a 2012 Dodge Avenger, thermostat replacement typically costs about $150–$350 in parts and labor, with higher totals if additional cooling-system repairs are needed. Always obtain a written estimate and clarify whether coolant, disposal, and any potential extra work are included.

How many thermostats does a 2012 Dodge Avenger have?


Many vehicles have two thermostats—one for the engine and one for the radiator or heater circuit. Locate the housings by following the upper radiator hose to the engine block and the heater hose to the firewall. Drain coolant before removal. Replace both thermostats and gaskets to ensure proper cooling system function.



How do I know if my Dodge car thermostat is bad?


  1. Overheating and Overcooling. Overheating is the most common symptom of a failing thermostat.
  2. Coolant Leaking. If you have experienced problems with overheating or notice liquid dripping under your car, it is a sure sign of a coolant leak.
  3. Strange Sounds and Temperature Changes.
  4. Heater Problems.



What is the recall on the 2012 Dodge Avenger?


Summary: Chrysler (FCA US LLC) is recalling certain 2012 Jeep Liberty and 2012-2013 Chrysler 200 and Dodge Avenger vehicles. A component within the occupant restraint controller (ORC) may fail and prevent the active headrests from deploying in the event of a rear-end crash.
