General information
- The cooling system is designed to maintain the optimal thermal mode of engine operation under any operating conditions. The engine uses a liquid cooling system with forced circulation of liquid through the cooling jacket of the cylinder block and cylinder head using a centrifugal pump. If the specified coolant temperature is exceeded, the thermostat opens and the coolant begins to circulate through the radiator, dissipating heat into the air.
- When the engine reaches normal operating temperature, the coolant expands and is forced into the expansion tank. As the engine cools, the cooling system is replenished from the expansion tank.
- The centrifugal pump is driven by a timing belt (GDI) or a drive belt (MPI) from the crankshaft pulley.
- The tubular-plate radiator is cooled by an electrically driven fan, which is controlled by the electronic engine control unit in accordance with the engine's thermal conditions.
Warning: When opening the expansion tank cap on a hot engine, care must be taken as hot steam and coolant may cause severe burns. If the radiator filler cap must be removed before the engine and radiator have cooled down completely (although this is not recommended), the pressure in the cooling system must first be reduced.
Warnings
- To avoid getting burned, cover the cap with a thick piece of cloth and slowly unscrew it until you hear a hissing sound. When the hissing stops, indicating that the pressure has decreased, continue to slowly unscrew the cap until it can be removed. If the hissing continues, wait until it completely stops. Always try to keep your face and hands at a safe distance when opening the cap.
- Do not allow antifreeze to come into contact with your skin or the painted surface of your vehicle. Wash off any spilled fluid immediately with water. Never allow antifreeze to sit in an open container or spilled on the driveway or garage floor. If the engine is hot, the electric fan may turn on even when the engine is off.
