There are two types of heating mechanisms: electric and mechanical. The mechanical mechanism of heating looks in the form of an aluminum case with an output and input pipes for coolant. The bimetallic spiral, located on its inner wall, is unclenched when heated, and compressed when cooling, thus acting on air throttle. The electric motor heating system includes a stepping electric engine that affects the lever of the shuttle drive. With a change in the temperature of the motor, the rods of the electric mechanism reduces or increases the engine speed. The step electric motor, as a rule, is installed on cars that are equipped with hydraulic amplifiers for steering. Then check the spark plugs, whether they are suitable according to the operating instructions. Check the spark. If the spark is weak – replace the candles. Unstable engine operation can occur in case of violation of the tightness of flanges in the manifold, adjacent to the head of the cylinder system. To do this, during the operation of the engine, spray the spray for cleaning the carburetor for gaskets of the intake manifold and carburetor. If the shaking of the motor has stopped, then the air penetrating through the gasket impoverishes the working mixture. It should be careful: the liquid for cleaning the carburetor is fire hazardous! The power of the engine can be reduced due to abundant pile forming in the valves and the combustion chamber. Such problems arise with frequent short trips with a small speed. Drivers with experience recommend periodically traveling on a suburban highway to ride with a breeze. At the same time, the carfire lags behind the cylinder wall and goes through the exhaust pipe. You also need to check the pressure in the motor cylinders.
