TOM: Yes, Lee, removing the thermostat does make the car run cooler. But you should never, ever do it.When the engine is too cool, the thermostat closes and stops the coolant from flowing through the radiator, so the engine heats back up.

Is it OK to run an engine 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.This will allow your engine to reach optimal operating temperature, improving gas mileage and performance.
How long can you drive without a thermostat?
If the engine gets hotter than the optimum temperature, you know it won’t be able to sustain the heat for more than 10 minutes and will eventually die. However, when your engine runs below the optimum temperature, your engine will die slowly yet certainly it’s a death by a thousand cuts.
Will my car overheat if I remove the thermostat?
TOM: Yes, Lee, removing the thermostat does make the car run cooler. But you should never, ever do it.When the engine is too cool, the thermostat closes and stops the coolant from flowing through the radiator, so the engine heats back up.
Can you drive a car with the thermostat stuck open?
A vehicle can run just fine if the thermostat doesn’t open. It will run on the warm side, not past halfway, and heat the interior just fine. But, when the weather gets warmer outside that thermostat stuck closed will not be able to allow the reservoir water flow and the vehicle will begin to have overheating issues.
Is thermostat important in a car?
Your car thermostat is an important part of your cooling system.As the coolant gets hotter, the thermostat opens, allowing coolant to flow through to the radiator to be cooled. The thermostat then opens and closes to keep the engine within a certain temperature range.
What happens if I unplug coolant temperature sensor?
What Happens If You Unplug The Coolant Temp Sensor? What is this? Unplugging the engine coolant sensor while the car is running will likely cause the engine to stumble and run rough. The engine light may not come on imminently, but a DTC (Diagnostic Trouble Code) will be logged in the PCM.
What are 10 common causes of overheating?
Common reasons for overheating engines
- Too little or no coolant. Driving without proper levels of coolant/antifreeze may cause a coolant system failure.
- Cooling system leaks.
- A broken water pump.
- Radiator issues.
- Oil too low.
- Thermostat failure.
- Issues with the belts and hoses.
- Heater core is plugged up.
What happens if a thermostat is stuck closed?
If the thermostat becomes stuck in the closed position, the circulation of the coolant is blocked so the coolant cannot get to the radiator to be cooled which causes the engine to overheat.
How often should you replace your car thermostat?
However, most car experts recommend car thermostat replacement after 10 years. However, this is an optimistic number. Thermostats are more likely to stop working much earlier than a decade. Some factors that induce an early thermostat failure include harsh weather, rough driving, bad engine or thermostat parts.
When should a thermostat open?
approximately 200 degrees Fahrenheit
until the engine is warm. When the engine is cold, the coolant will not flow through the engine. As the temperature rises, however, the thermostat slowly begins to open. By the time the engine reaches approximately 200 degrees Fahrenheit, the thermostat will be open entirely.
What are the signs of a bad thermostat?
5 Symptoms of a Bad Thermostat (and Replacement Cost)
- #1 Temperature Gauge Reading Higher (or Lower) Than Normal.
- #2 Sudden Air Temperature Changes Inside Vehicle.
- #3 Coolant Leaking.
- #4 Rumbling Noises.
- #5 Heater Malfunction.
What are the signs of a bad car thermostat?
Symptoms of a Bad or Failing Thermostat
- Temperature gauge reading very high and engine overheating.
- Temperature changing erratically.
- Coolant leaks around the thermostat housing or under the vehicle.
Can a temp sensor affect engine starting?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
Can coolant temperature sensor cause overheating?
Overheating engine
The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.
Does the coolant temp sensor control the fan?
The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system.As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
How can I stop my car from overheating while driving?
Radiator cooling fan
- Park your car in the shade.
- Use car window shades.
- Tint your windows.
- Leave car windows open slightly.
- Turn the floor air vents on.
- Use the fresh air setting instead of recirculation on your A/C.
- Keep your eye on the car temperature gauge.
- Turn on the heat to cool the engine.
How many times can a car overheat before damage?
You have around 30 to 60 seconds before you start to do serious damage, such as seized up valves or even pistons, if it reaches maximum hot.
How do I know if my car engine is overheating?
Warning Signs that Your Engine is Overheating
- Hot Hood. When the engine is running, you can expect the hood to emit heat and feel warm to the touch.
- Temperature Gauge or Light.
- Ticking Noise.
- Coolant Leaking on the Ground.
- Smells Hot
- Steam Coming from the Hood.
- Thumping Noises.
- Reduced Engine Power.
Can a stuck thermostat cause pressure?
A failing thermostat would absolutely cause the system to overheat and build pressure. If you are already seeing signs of leaking near or from the thermostat housing there is a good chance this is where the problem lies.
Should I replace thermostat with radiator?
Aside from this type of preventive maintenance, a thermostat doesn’t need to be replaced unless it stops opening and closing when it’s supposed to. If it sticks in the closed position, that traps coolant in the engine so that it overheats.
