less heat in your car
Overheating or no heat from the heater are sure signs it is bad. You car is 12 years old, just replace it if you have a suspicion it is bad. You can test the thermostat but why bother? You will have to remove it to perform the test. Just replace it.
When a thermostat goes bad in a vehicle, it can make your car overheat. It can also make it t where you do not have any heat inside your car.
yes
It most likely means that your thermostat has gone bad. The engine of your car is running too cold and you need to get a new thermostat installed.
Yes a bad thermostat would cause overheating in any car. A thermostat regulates the temperature.
Yes
Car overheats, your heat in your car stops working
low or no coolant, or a bad thermostat.
It is important to recognize the signs of part failure in a car. The signs of a bad rack and pinion are unusual tire wear, the steering is off, and fluid leaking from the front end of the car.
If thermostat does not open - Vehicle will overheat in a short time - no heat If thermostat does no close - vehicle will not get to normal operating temperature - no heat
When the car is hot, squeeze the upper radiator hose. If it feels soft, then the thermostat is not opening and therefore bad. If you squeeze the hose and its hard to squeeze, then it is pressurized and the thermostat is open. That is one way to check if the thermostat is stuck closed. If the thermostat is stuck open, then in cold conditions the car will take a long time to produce hot air from the heater.
