How do I know if Dodge car thermostat is bad?

Signs of a Bad Dodge Car Thermostat
If you suspect that the thermostat in your Dodge car may be bad, there are several signs you can look out for. Here are some common indicators of a faulty thermostat:
1. Temperature gauge readings: Your Dodge car’s temperature gauge on the dashboard can provide valuable information about the state of the coolant and whether there is an issue with the thermostat. If the gauge shows abnormally low or high readings, it may indicate a problem with the thermostat.
2. Overheating or overcooling: A malfunctioning thermostat can cause your engine to overheat or run too cool. If your engine temperature spikes quickly after starting the car or if it consistently runs colder than normal, it could be a sign of a bad thermostat.
3. Coolant leaks: If you notice liquid dripping under your car or experience frequent overheating, it could be a sign of a coolant leak, which may be caused by a faulty thermostat.
4. Odd temperature gauge readings: Your temperature gauge should register cold when you start your car and gradually increase to normal as the engine warms up. If the gauge readings are consistently lower or higher than normal, it may indicate a problem with the thermostat.
5. Strange sounds: Rumbling sounds coming from the engine or radiator could be a sign of a bad thermostat, as coolant flow issues can cause unusual noises.
It’s important to address a failing thermostat promptly to prevent further damage to your engine. If you notice any of these signs, it may be a good idea to have your thermostat inspected and replaced if necessary.
