What is the reason for Jetta's high temperature?

The high temperature of Jetta car may be caused by the damage of temperature sensor and loose fan belt. In addition to the two reasons mentioned above, poor antifreeze circulation, insufficient antifreeze or excessive scale in the engine, and improper closing of the engine throttle will all lead to engine exhaust pipe blockage. When the engine is working, the temperature is reduced by air cooling and water cooling, that is, the cooling fan, coolant and water tank play the role of cooling the engine. Therefore, the temperature rise of the engine can only be caused by the temperature of these two internal components, and the most important device on which these two components depend is the thermostat, that is, the temperature sensor. If the thermostat doesn't open, it will cause the temperature of the vehicle to rise. Million car purchase subsidy
