Can you run a vehicle without a thermostat?
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. In this case though, the thermostat is not present, so this would not be a problem.
What happens when a car doesn’t have a thermostat?
If you drive without a thermostat, your engine will never reach its optimal operating temperature and your heater may blow cold air. It happens because driving without a thermostat tricks your engine into thinking it is cold outside, causing it to adjust the gas mixing valve and push more fuel to the engine.
Should you run a thermostat in a drag car?
Since you are running an electric water pump, I would run no thermostat. You can turn on the pump in the pits or in the staging lanes and the water will still flow to cool the engine. If you have a thermostat and it is closed, you will get no flow. You should use some sort of flow restriction though.
Does a thermostat add horsepower?
If you hang around car guys long enough, you will hear that a colder thermostat will help you make more power. However, a low-temp thermostat by itself does not make power. In some circumstances, a colder thermostat can help the engine make more power. But it’s not the lower temps that do it.
Is a higher temp thermostat better?
A hotter thermostat will tend to make an engine more efficient from a fuel mileage and emissions standpoint. It might also reduce horsepower by a few percent and, if the thermostat temperature is higher than the factory recommends for the specific vehicle, it might cause internal engine parts to wear at a quicker rate.
What happens if you remove thermostat in car engine?
TOM: Yes, Lee, removing the thermostat does make the car run cooler. When the engine is too cool, the thermostat closes and stops the coolant from flowing through the radiator, so the engine heats back up.
Will no thermostat cause overheating?
Running an engine without the thermostat can cause the engine to overheat due to the coolant passes through the engine too fast and will not let the coolant absorb the heat from the engine.
Do colder thermostats increase power?
