Engine Cooling Module
In the Astra-G with petrol engines, the engine cooling module is equipped with either one or two radiator fans, depending on the equipment version (with / without air conditioning). The models with diesel engines are all equipped with two radiator fans. Actuation of the radiator fans is controlled by an additional engine cooling module control unit.
