The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens.
To let the engine warm up by closing flow of coolant. When operating temperature is reached the thermostat pops open allowing full flow of coolant. Totally necessary in winter !
All car engines need to run at a minimum temperature or excess engine wear and poor fuel economy will result. In tropical climates where in hot weather people remove the thermostat to improve their chances of not overheating Instead they would be better to use a 160o F thermostat and maintain the minimum good temperature for the life and service of the engine.
Yes, the hypothalamus is similar to a thermostat because it controls the body temperature. The thermostat in a home or in a car is what controls that things temperature.
it can start but it won't go far as the engine will "explode" because of the increase of temperature. A thermostat regulates the temperature system of your car.. Usually the engine will run too cold with out a thermostat. That will hurt the efficiency of the engine.
It depends on what type of car you are working on. all cares have different temperature thermostats. A very common temperature is 195 degrees
Your car is starting to overheat or your thermostat is going out. Get it checked.
Depends on car, example: it could be 180 - 195. There is the rating on thermostat
The Coolant Temperature sensor is defective.
Stuck open thermostat.
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
All cars can be driven without a thermostat. The thermostat is used to heat the car in winter by forcing the water temperature up.
