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

How to Determine if Your Dodge Durango Thermostat is Bad
If you suspect that your Dodge Durango thermostat may be faulty, there are several signs and symptoms to look out for. Here are some indicators that your thermostat may be bad:
1. Check Engine Light: A failing thermostat may cause the Check Engine Light to illuminate on your dashboard. This is because the thermostat may fail to close completely, preventing the engine from reaching its normal operating temperature.
2. Fluctuating Temperature Gauge: If you notice that the temperature gauge on your dashboard shows an increase in water temperature followed by a sudden drop back to normal, it could be a sign of a bad thermostat.
3. No Heat: A malfunctioning thermostat can result in a lack of heat inside the cabin of your Durango. If you’re experiencing a lack of warm air when the heater is turned on, it could be due to a faulty thermostat.
4. Overheating: A spiked temperature gauge or frequent overheating can be a symptom of a bad thermostat. If your engine is consistently running hot or overheating, it’s worth considering the thermostat as a potential culprit.
5. Coolant Leaks: While a coolant leak is not directly caused by a bad thermostat, it can be a symptom of a failing thermostat. If you notice coolant leaks in your Durango, it’s important to have the thermostat checked as part of the diagnostic process.
It’s worth noting that these symptoms can also be caused by other issues with the cooling system, so it’s important to have a professional diagnosis to confirm the exact cause of the problem.
If you suspect that your thermostat is bad, it’s recommended to have it replaced by a qualified mechanic. The average cost for a Dodge Durango thermostat replacement is between $427 and $447. Replacing a thermostat is a relatively affordable repair, and ignoring a bad thermostat can lead to more costly engine damage in the long run.
Remember to consult with a professional mechanic for an accurate diagnosis and to ensure the proper repair of your Dodge Durango’s thermostat.
