If the temperature goes up and down and the coolant level is ok your thermostat is probably sticking. Replace the thermostat and you should solve the problem.
That is one of many possible causes.
forward friction on the tyres from the road..
Lack of or improper maintenance.
In ancient buddhism readings people say it is desire that creates suffering'
it needs a tune up
Liquids in hydraulic brakes help to stop an automobile by creating pressure and moving a set of pistons to generate force. This force is applied outward and causes friction that stops the automobile.
The most common causes of failure of automobile thermostats are rust and debris buildup in the cooling system which can cause binding of the moving mechanism and leakage of the wax cup so that the proper pressure is not exerted to open or close the moving mechanism.
An electrical fire in an automobile is usually caused by a short circuit. For example, If there are exposed wires somewhere, touching metal, that could start a fire.
try changing the coolant temperature sensor that gives the computer it readings , it's located on the thermostat houseing and cost about 10 -15 dollars.
revolution of earth around the sun causes the variation in the temperature..
Technically no. Temperature is effectively the average speed of the particles. If you don't have any particles then you have no temperature. Although an Infra-red detector would work, and Infra-red radiation causes heating, that would not be the temperature. Also, this is all theoretical anyway since total vacuums do not exist.
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
