Engine cooling system with a displacement of 1.6 liters (4A-FE)
The engine cooling system consists of a radiator, coolant pump, thermostat and electric fan.
The cooling system is thermostatically controlled. Until the engine is warmed up, the coolant circulates only in the cylinder block and the heater heat exchanger. As the coolant heats up, the thermostat opens slightly and directs fluid flow through the radiator. The circulation of fluid in the system is provided by a coolant pump driven by the engine through a reinforced V-belt (diesel through toothed belt). The coolant flows through the radiator from top to bottom and is cooled by air blowing over the grille while the car is moving.
Additional cooling of the system is carried out by an electric fan. When the coolant reaches a temperature of +92°C, the thermal switch turns on the fan. When the cooling temperature drops below +82°C, the thermal switch turns off the electric fan.
The expansion tank is used to compensate for fluctuations in the volume of the coolant. Through the expansion tank, the system is filled with coolant.
Note: The electric fan can switch on automatically when the engine is stopped and the ignition is switched on. This is a consequence of the presence of thermal stagnant zones in the engine compartment. This circumstance should be borne in mind when working in the engine compartment. Therefore, when working in the engine compartment, if possible, turn off the ignition.
