Two types. Electric has a heat sensitive resistor immersed in the coolant and the dial is actually a voltage meter. Capillary has a tube containing a sensitive liquid attached to an aneroid at the gauge end and immersed at the other end. When the liquid expands it pushes on the aneroid which is attached to a needle.
Because car manufacturers design their products to function.
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.
Mine was a bad ground on the gauge. Easy check by any certified mechanic.
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.
because the engine in that car does not cool down
A signal from the temperature sensor on the engine.
Start with the fuses, then go to the more complex problems
Bad gauge or defective coolant temperature sensor
you need a newvoltage reducer
well your car needs a new body kit because that contributes to the temperature of the car
If it gets to hot the thermostat wont work. you need to repace it and the gauge will work again.
