How does a car run without a thermostat?
You may think your engine would overheat without a thermostat in place, but actually, the opposite is true. A car without a thermostat would never even warm to operating temperature, much less overheat. The lack of a thermostat would create a constant flow of coolant through the engine, thus a constant cooling effect on the engine.
What does it mean when your car thermostat is warm?
If the hose is warm it means that your car’s thermostat has gone bad and is stuck open. It’s letting coolant pass through when it should not. If the top radiator hose is cool, start the engine again and let the engine reach its operating temperature. This is a great sign but we’re not done yet.
What to do if your car thermostat is stuck?
However, a stuck closed thermostat is rare and when it happens – you’ll definitely notice because the engine will start to overheat, therefore you can skip the last two steps. Shut the engine off and feel the warmth of the top radiator hose again. Be careful – at this point, the hose should be hot, so cover it with a rag when touching it.
How big is the thermostat in a car?
Car thermostats are the small device that sits between the radiator and the engine of a liquid-cooled car. The thermostat in most cars is about 2 inches (5 cm) in diameter and play an important role in the car which is to regulate the flow of the engine coolant from the engine to the radiator.
What should the temperature be in a car with no thermostat?
The average temperature a car engine is expected to run in is 80-100 degree centigrade. If you drive your car without a thermostat, it will run at 50 degree centigrade. When the car drives at this temperature, moisture or humidity will form.
Where does the thermostat go in a car?
TOM: The thermostat is just a valve that goes between the engine and the radiator. It’s purpose is to keep the engine at the proper operating temperature. When the engine gets too hot, the thermostat opens up and lets the engine coolant flow through the radiator, where it cools off.

How does the thermostat keep the engine cool?
When the engine heats up, the thermostat will expand and allow the coolant to flow to the engine to keep it cool. It also prevents the coolant from flowing to the radiator till the engine heats up. (it maintains a proper temperature so the engine doesn’t go cold).
