Most cars will work without a thermostat. The purpose of the thermostat is to allow the engine to warm up more quickly by reducing the flow of coolant to and from the radiator. Because of the excessive cooling, however, your engine will not run at the right temperature under cool conditions and you may have excessive engine wear, reduced fuel efficiency and reduced passenger heat. In an emergency though, it's fine.
You could have a problem with your thermostat in the car.
If your thermostat isn't working then the gauge on the car won't work. You may also notice that your car runs hot.
No
I assume you mean "When your hot water needle does NOT work." Thermostat.
is car thermostat necessary in a tropicalize car?
sometime the fan do not work which can cause the car to overheat. Also it can be a fuse for the fan. Check your thermostat.
Check your thermostat, it is either stuck open or not in the engine.
Yes the temperature gauge will still work. If it stuck open the car will run cool. If it is stuck closed the car will overheat.
Take your thermostat out and put everything back together, run your car without a thermostat... If your car no longer overheats, replace your thermostat.
You might need a new thermostat or heater core.
no, the thermostat would have nothing to do with the car not starting.
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.
