The fan is driven by an electric motor, which is installed in the radiator casing and is switched on by a thermal switch.
Warning: The fan may run even when the engine is already off. Disconnect the negative battery cable whenever you work near the fan.
The water pump is mounted on the front of the engine and is driven by a timing belt.
The heater uses the coolant heated by the engine to heat the vehicle interior. The fluid passes through the core of the heater, similar to a radiator, and puts on the air driven through the heater. Through the ducts, warm air enters the cabin. The regulation of the circulation of coolant and air through the core is performed by the driver.
Some models have an air conditioner. The air conditioning system is located in the engine compartment. The compressor is driven from the crankshaft pulley by means of a drive belt.
