Cooling system components
Water pump. Centrifugal type water pump circulates coolant through the cooling system
Radiator. All models are made of light metal. The radiator consists of two tanks connected to each other with many thin-walled tubes. To increase the cooled surface, accordion-folded plates are inserted between the tubes, which collect excess heat and give it to the oncoming air flow. The radiator is mounted on the upper and lower crossbars.
Thermostat. This temperature-dependent controller controls the coolant circuits.
At temperatures up to +85°C, the valve on the thermostat blocks access to the radiator, and the coolant circulates in a closed circuit (engine).
At temperatures from +85 to +100°C, the thermostat partially opens the passage of the coolant to the radiator. The passage to the water pump remains more or less open. The cold fluid from the radiator gradually mixes with the warm coolant before entering the engine.
The thermostat valve is fully open at temperatures above 100°C, in which case all the coolant passes through the radiator.
Expansion tank. The required amount of coolant circulating in the cooling system is added to it. The excess pressure created in the expansion tank is equalized by a pressure reducing valve located in the tank cap.
radiator fan. Designed for more efficient air cooling of the radiator. Depending on the type of engine and vehicle equipment, a viscous fan or an electric fan is installed.
