What are the symptoms of a stuck thermostat?
Symptoms of a Bad or Failing Thermostat
- Temperature gauge reading very high and engine overheating. The first and potentially most alarming symptom will be the temperature gauge reading high into the red within the first 15 minutes of your vehicle engine running.
- Temperature changing erratically.
- Coolant leaks around the thermostat housing or under the vehicle.
How can you tell if your thermostat is stuck?
If you see your temperature gauge going into the red within the first 15 minutes of driving, your thermostat may be bad. Generally, if your vehicle is overheating within 15 minutes or so of driving it, this may be a sign that the thermostat is stuck. Step 2: Check the radiator hoses.
How do I get my thermostat unstuck?

What causes a car’s temperature gauge to rise?
If the temperature gauge reads high, it could mean your engine is overheating. Another reason your reading might be high is you could be losing coolant. A small leak or evaporation may cause your radiator to slowly lose coolant. A third reason your temperature gauge reads high could be because the thermostat is broken.
What temp should a 454 run?
