It will not be possible to heat the engine up to the working temperature in the severe frosts, not on every car, and often it does not indicate a malfunction. The engine may not be warmed up in a heavy cold while driving along the highway at high speed: the oncoming air streams cooled the radiator and the temperature dropped. But if the engine started to warm up much longer or did not warm up to the right temperature even during the trip, it should be checked.
The first thing to do is check the thermostat. It could have been curled and the coolant fluid began to circulate through a large circle of cooling through the radiator, and began to cool instead of heating. To understand which circular fluid is circulating, you must touch the heater radiator-radiator-they must be hot. The thermostat from the thermostat to the thermostat shall only be a little warm. It is heated only when the coolant starts to circulate through a large circle through the radiator.
Another cause of poorly warmed engine may be the cooling of the cooling system. In this case, the leakproofness of the cooling system should be checked first and try to find out where the air falls into the system. Then the system needs to be pumpsiper.
Many modern machines are equipped with high efficiency engines and small thermal units. This is particularly pronounced in small turbo motors. Such engines may be poorly warmed due to design features. In this case, the problem can only be solved by insulating the engine during the winter period.
