How do I know if Dodge car thermostat is bad?
The thermostat in your Dodge vehicle plays a crucial role in regulating the engine's temperature. It ensures that your engine warms up quickly and maintains an optimal operating temperature. A malfunctioning thermostat can lead to overheating, poor performance, or even engine damage. In this article, we’ll explore the signs of a bad thermostat and what you can do about it.
Signs of a Bad Thermostat
Recognizing the symptoms of a failing thermostat early can save you from costly repairs. Here are the most common signs to watch for:
- Engine Overheating: If your engine temperature gauge consistently shows that the engine is running hot, it could indicate that the thermostat is stuck closed, preventing coolant from circulating.
- Temperature Fluctuations: A faulty thermostat may cause erratic temperature readings, with the gauge moving up and down unpredictably.
- Coolant Leaks: A stuck thermostat can cause pressure to build up in the cooling system, leading to leaks around the thermostat housing or other components.
- Heater Not Working Properly: If the thermostat is stuck open, the engine may not reach the proper operating temperature, resulting in insufficient heat from the cabin heater.
- Check Engine Light: In some cases, a bad thermostat can trigger the check engine light due to abnormal temperature readings detected by the engine control unit (ECU).
How to Confirm a Bad Thermostat
If you suspect your thermostat is failing, here are some steps you can take to confirm the issue:
- Inspect the Temperature Gauge: Start your car and monitor the temperature gauge. If it takes too long to warm up or overheats quickly, the thermostat may be the culprit.
- Check for Coolant Flow: With the engine running and warmed up, carefully check if coolant is flowing through the radiator. A lack of flow could indicate a stuck thermostat.
- Feel the Radiator Hoses: After the engine has warmed up, carefully touch the upper and lower radiator hoses. If one is hot and the other is cold, the thermostat may not be opening properly.
What to Do If Your Thermostat Is Bad
If you’ve determined that your Dodge car’s thermostat is faulty, it’s important to address the issue promptly. Here’s what you can do:
- Replace the Thermostat: Thermostat replacement is a relatively straightforward repair. Consult your vehicle’s manual or a trusted mechanic for guidance.
- Flush the Cooling System: If the thermostat has been stuck closed, it’s a good idea to flush the cooling system to remove any debris or contaminants.
- Check for Additional Damage: Overheating caused by a bad thermostat can damage other components, such as the radiator or head gasket. Have a professional inspect your vehicle for any further issues.
Preventing Thermostat Issues
To avoid thermostat problems in the future, follow these maintenance tips:
- Regular Coolant Changes: Replace your coolant according to the manufacturer’s recommendations to prevent buildup and corrosion.
- Inspect the Cooling System: Periodically check for leaks, worn hoses, or other signs of wear in the cooling system.
- Address Overheating Promptly: If your engine overheats, don’t ignore it. Investigate the cause immediately to prevent further damage.
By staying vigilant and addressing thermostat issues early, you can keep your Dodge running smoothly and avoid costly repairs down the road. If you’re unsure about diagnosing or repairing a thermostat issue, don’t hesitate to contact a trusted auto repair shop like Kevin’s Autos for professional assistance.

How often do thermostats go bad in a car?
10 years
A car thermostat is designed to last a long time – typically around 100,000 miles or 10 years. However, various factors can impact its lifespan. First, driving conditions play a role. If you regularly drive in hot weather or stop-and-go traffic, your thermostat may suffer additional stress.
What are the symptoms of a bad thermostat in your car?
5 Signs Your Thermostat Is Broken
- You Notice Erratic Temperature Changes.
- You Find Incorrect Readings on the Temperature Gauge.

Can you replace the thermostat without replacing water pump?
A defective water pump cannot be repaired, it must be replaced with a new one. It is a common practice to also replace the vehicle's thermostat when doing a water pump replacement. It is not always needed, but if you suspect that your engine got hot when the water pump failed, it's a good idea to take care of it.
How can I test if my thermostat is bad?
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.
Can you drive a car with a bad thermostat?
If you drive with a bad thermostat, your car could overheat, causing severe and expensive engine damage. And while it's technically possible to drive without a thermostat, we don't recommend it. Your car will not reach an acceptable operating temperature, resulting in higher fuel consumption and excessive engine wear.
