Do you need to take the thermostat out of your car?
Even if your radiator cap is accessible, you can actually do both tests, since neither requires removing the thermostat from your car and they both only take a few minutes. With an overheating engine problem, it’s a good idea to have an assistant behind the wheel to shut off the engine if the temperature reaches an unsafe level while testing.
How can you tell if your car thermostat is stuck?
To quickly tell if your thermostat is stuck, watch the flow of coolant through your radiator. For a more accurate test, measure the temperatures of the engine and the hose leading to the radiators to see if they’re similar.
Is it safe to drive without a thermostat?
Most automobile mechanics will tell you it is not a good idea to drive your car without a thermostat installed. If your thermostat becomes stuck in the closed position, though, this will cause your engine to overheat and make driving your car impossible.
What happens if your engine thermostat is too hot?
Thermostat, that fits in Toyota A, E, S and C engines. What Does the Engine Thermostat Do? If a car’s engine is too hot, it can actually warp and become damaged. But, when it’s cold, it doesn’t run efficiently. So, it is important to keep the engine at the right temperature, which is where the thermostat comes in.
How can you test a car thermostat without removing it?
There is a more accurate way to do this but it requires a thermometer to know the exact temperature of the water: Determine the opening temperature of the thermostat. Place the thermostat in room temperature water and start boiling it. Keep checking the temperature of the water with your thermometer.
What does it mean when your car thermostat is stuck?
Interpreting your results: If both test points remain at about the same low temperature, your car thermostat is stuck opened. This means the coolant is flowing continuously, keeping the engine from reaching operating temperature. It takes between 15 and 20 minutes for the engine to reach operating temperature.
When do you open the thermostat on your car?
When you start your car after it has been sitting, such as in the morning, the thermostat is closed and remains that way until the coolant builds to a specified temperature. Your thermostat is designed to then open up when the coolant reaches this specific temperature, allowing coolant to flow into the radiator.
Can a car thermostat be put in the radiator?
You can certainly allow coolant to move freely into the radiator, but the reason why engineers put a thermostat in the way is because the car’s engine needs to reach the operating temperature as soon as possible.
