Description of the cooling system (Fiesta 2)

The cooling system removes excess heat generated in the engine. A certain portion of the heat removed from the engine is used to heat the car's interior. The design of the cooling system, as well as the regulation of the passage of coolant through heat exchangers and, above all, the radiator, allows the engine to warm up to normal operating temperature fairly quickly.

In the initial phase after starting a cold engine, the thermostat opens the circulation of the coolant through the car's interior heater. After reaching a certain coolant temperature, the thermostat turns on the circulation through the engine radiator, located in the front part of the car. If the temperature of the liquid continues to increase, the radiator fan turns on. The fan is turned on by a thermal switch located in the radiator. The air flow, thus increased, passes through the radiator grille, intensifies heat removal and reduces the temperature of the coolant (Fig. 2.87 and 2.88).





The water pump is mounted at the front of the engine. In the 1.1 engine, the water pump is driven by a V-belt together with the radiator fan. In the 1.4i/1.6i engines, the water pumps are driven by toothed belts, and in the diesel engine, by the alternator drive V-belt.
