On the warm part of the engine, the stove is not warm, especially in the LADA Kalina. What's the problem?
If the thermostat is in good condition, this is usually caused by an air traffic jam in the "small" circuit of the exhaust system of the OJ, from which the liquid is attached to the heater radiator. If the covers of the expansion bull are operating normally, the problem shall be solved after the warm-up liquid has been warmed up to the full opening of the thermostat of 101 °C. If the liquid does not clearly warm up to the operating temperature or is warmed up only 15 to 20 minutes, then the thermostat must be changed again.
