Ancillary components that are in perfect working order give drivers a strong feeling of comfort and security.

The V belt is responsible for ensuring that the air conditioning compressor it drives regulates the temperature inside the vehicleto a pleasant level in summer and stops the windows misting over in winter. It also ensures that the power steering assists the driver when steering.

The alternator drive ensures not only that the necessary electrical energy (e.g. for sparking ignition or for the injection system) is supplied to the engine but also that electrical loads such as the heated rear window, lighting, heated seats, the navigation system and the ABS and ESP are supplied with power. The water pump powered by the drive ensures that the coolant circulates in the engine, thereby preventing the inconvenience that would be caused by breaking down due to the engine overheating.
