Why is the car hot?

Probably, every motorist has a moment in practice, when he asks himself or the master of the SRT this question: why does the car get warm? An overheated engine is a big problem for the car and your wallet. So, the most famous cases when the car is heated:

  1. Thermostat malfunction. The sticking of the valve assembly leads to the fact that the coolant "chases" in a small circle of circulation, without having time to cool the engine.
  2. Insufficient fluid in the cooling system (water, antifreeze, antifreeze). Perhaps due to defects in the pipes, cracks in the radiator, destruction of pump parts.
  3. Low efficiency of air cooling radiator. Causes: a clogged radiator, poor functionality of the fan drive, a malfunction of the sensor of the electric drive of the fan.
  4. Long engine operation under abnormal conditions. These are downtime in traffic jams, protracted rises of a laden car at low speeds. In this case, the fan’s own power is not enough, and the air flow is absent, as a result of which cooling does not occur, and this is why the machine heats up.
  5. Incorrect adjustment of the ignition and injection system - the end of the combustion of the fuel is displaced by the time the exhaust gases are released. There is a significant increase in exhaust gas temperature, and the engine receives half the heat from the exhaust system.
  6. It should be noted the case when the engine is heated. This is the work on the rolling mode after the overhaul (about 2-4 thousand km. Of run). Here it is necessary to closely monitor the sensors and not to overload the engine more than the running-in rate.

Summing up, remember, a car is a complicated mechanism. And mechanisms like maintenance and constant monitoring, so if the car is warming, do not disregard it. In time, identify the cause and eliminate it.
