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.

Temperature Gauge Issues
Place the thermostat into the water and watch the temperature gauge. If the thermostat gauge doesn’t go up, spikes, or goes up far beyond the actual temperature of the water, then your thermostat likely needs to be replaced.
Will a stuck thermostat throw a code?
Yes, if the thermostat is not working correctly, it will throw a code and turn on the check engine light. The thermostat is responsible for regulating the engine’s coolant temperature. If it is not working properly, the engine can overheat.

5 Signs Your Thermostat Is Broken
- You Notice Erratic Temperature Changes.
- You Find Incorrect Readings on the Temperature Gauge.
- Your Vehicle Makes Concerning Noises.
- You Find Coolant Leaks.
- You Notice Problems with the Heating System.
How do I know if my thermostat is stuck open or closed?
Bad there are two main scenarios. It can get stuck closed or stuck open when the thermostat is stuck open engine. Will take a long time to warm up.
How can I test my thermostat?
Possible. This thermostat is reading 01 meaning. It’s fine this thermostat has no reading at all so this is the faulty one and needs to be replaced.
How do I know if my thermostat is faulty?
A bad thermostat can be detected when your AC or furnace is not turning on, your HVAC systems are not turning off, the thermostat not responding, your HVAC system is short-cycling, the room temperature not matching the temperature displayed on the thermostat, and the programmed setting resetting themselves.
Will a bad thermostat throw a code?
Yes, if the thermostat is not working correctly, it will throw a code and turn on the check engine light. The thermostat is responsible for regulating the engine’s coolant temperature. If it is not working properly, the engine can overheat.
How does a car act when the thermostat is bad?
The car will not reach its normal operating temperature as soon as it would usually. the open thermostat allows more coolant to flow through the radiator instead of trapping coolant in the block and heating it faster. On cold days that means that you can’t get heat into the passenger cabin as quickly as you might like.
What are the symptoms of a stuck thermostat?
Overheating (or overcooling)
With that said, overheating is the most common symptom of a bad or a failing thermostat. This happens because a thermostat can get stuck as it ages. If it’s stuck in the closed position, it won’t let the coolant reach the radiator and the engine will overheat.

Signs My Car’s Thermostat Is Going Bad or Has Failed Completely
- Odd Temperature Gauge Readings. Your temperature gauge should register cold when you first start your car and slowly build up to normal as the engine warms up.
- Air Temperature Changes.
- Coolant Leaks.
- Strange Sounds.
- Heater Problems.
