Alternator VW

Can I drive my VW with a faulty alternator?

The occasional malfunction of the component can cause damage to the battery and other electrical devices in the vehicle. Therefore, faults need to be fixed as soon as they are first detected.

If the device stops working completely, the vehicle cannot be used because the battery won’t be charged. Sometimes the battery charge is only enough to reach the nearest service station. If a situation like this arises, you can take the following steps to reduce energy consumption:

• Keep the engine running if possible. It takes a lot of power to restart it.
• Turn off the car radio, the air conditioner, and other power consumers.
• Try not to use the high beam headlights.

What factors do I need to consider before choosing an alternator?

• Design: the body size and shape, and the number of holes and the distance between them. The product must match the specifications of the factory-installed equipment. Otherwise, it may be difficult to install the device.
• Pulley type. In most modern models, it has six grooves for a V-ribbed belt. However, certain VW commercial vehicles have toothed pulleys designed to be gear-driven.
• The cooling method. Most devices have an impeller. However, some vehicles with large engines feature water-cooled alternators. Antifreeze circulates around the system.
• Power. When additional electrical appliances and a high-capacity battery are installed, it may be necessary to install a more powerful alternator.
• Manufacturer. Reliable products are manufactured by the brands Ridex, Bosch, Alanko, DT, Hella, and Febi Bilstein.

Can I replace the alternator in my VW myself?

Yes, if you have enough experience and the right skills. Refer to the specific repair manual for your vehicle for detailed instruction on how to do this. The devices connected to the engine cooling system should be replaced at a car workshop.
