Description of the cooling system (Chevrolet Aveo T250)

The cooling system ensures the proper temperature in all operating modes of the engine.

The cooling system consists of a radiator and circulation system, fans, thermostat, and coolant pump.

The timing belt drives the coolant pump.

The pump circulates the coolant in the system. The coolant passes through the water jacket passages in the engine block, intake manifold and cylinder head. When the coolant reaches the operating temperature of the thermostat, it opens. The coolant then enters the radiator, where it is cooled.

The system directs some coolant to the heater core. The expansion tank is connected to the radiator to compensate for the expansion of the fluid. The expansion tank ensures the required level of coolant in the engine. The cooling system in this vehicle does not have a radiator cap or filler neck. The fluid is added through the expansion tank.
